Note to User
When using the Visual KV Series in the following conditions or environments, be sure to use the Visual KV Series with sufficient margin regarding the rating and functions, take appropriate safety precautions such as fail-safe, and contact our sales personnel if any questions arise. Use in conditions or environments not described in this manual Use for nuclear power control, railway facilities, air service facilities, vehicles, combustion devices, medical equipment, amusement machines, safety equipment, etc. Use for applications where large effects are predicted to be given on human lives and properties and safety is especially requested.

Restriction on Acquiring the CE Marking

Restriction to be compatible with EMC directives When using a relay output type unit (whose model name ends with "R"), connect spark killers having the appropriate withstand voltage against the load to the output terminals in parallel to contacts (because the unit discharges when a relay contact becomes open and noise is generated). In our experiments, we use the following models of spark killers. XEB0101 0.1 F-10 manufactured by OKAYA DENKI SANGYO The following 1-turn ferrite core is added to the AC power input circuit of the KV40AR/T, the KV-24AR/T and to the DC power input circuit of the KV-40DR/T. ZCAT3035-1330 manufactured by TDK Note: The contents above do not by themselves ensure that the entire machine manufactured in accordance with the above contents is compatible with EMC directives. You must judge by yourself whether or not the entire machine is compatible with EMC directives because compatibility may change depending on the component configuration, wiring and location inside of the machine. Restriction on compatibility with low-voltage directives (IEC-1010-1) Use insulated type crimp-style terminals. For wiring materials, use lead wires whose sheath is 0.4 mm or more. The Visual KV Series is allowed to be installed in a vertical position only. (Spacers for expansion units are not available.) Be sure to use the Visual KV Series inside the control panel.

Features of the Visual KV Series

Extremely small The Visual KV Series is the smallest in the world among AC type PLCs equipped with screw terminal blocks, and saves installation space. Extremely fast The minimum scan time is 140 s and minimum instruction execution time is 0.7 s, which is the fastest control in its class. AC power built-in type newly added AC power built-in type units are newly added. This type can be used in small spaces where a switching power supply unit cannot be installed. Excellent Access Window An Access Window with two-color backlight is adopted in all models to facilitate changing and monitoring of device data. Changing between RUN mode and PROGRAM mode, checking the error code when an error has occurred, etc. can be performed in a Visual KV Series unit without the need for any handheld programmer. The analog trimmer, which has been popular in the conventional KV Series, is digitized to enable more detail settings. [Digital trimmers] User message setting function In the Access Window, 256 different user messages can be displayed. This function can be used to give instructions on works on the production line, indicate abnormalities in the units, etc. Program write in RUN mode Ladder programs can be changed even while the system is running. Equipped with two serial ports Visual KV Series basic units are equipped with two serial ports to connect peripheral units, improving the debug environment. (The KV-10xx is equipped with only one serial port.) Easy Ramp-up/down control function The one-axis motor control function is offered separately from high-speed counters so that feedback control is enabled. Equipped with two 24-bit high-speed 30 kHz, two-phase counters The Visual KV Series is equipped with two high-speed counters each with a twopoint comparator output function that enables high-speed encoder input. Specified frequency pulse output function High-speed counters can function as pulse oscillators of 50 kHz maximum with easy setting, without creating a complicated ladder program. Frequency counter function High-speed counters can function as frequency counters with easy setting, without creating complicated ladder programs. Cam switch function High-speed counters can function as cam switches with easy setting, without creating complicated ladder programs.

(3)

 Interrupt function The Visual KV Series is equipped with four high-speed interrupt inputs of 10 s maximum. Input time constant change function The time constant can be set in 7 steps from 10 s to 10 ms. Double memory backup functions In addition to a conventional SRAM battery backup function, the Visual KV Series is also equipped with an EEPROM backup function.

Compatibility with Conventional KV Series Peripheral Units

The Visual KV Series functions as a high-end compatible model of the conventional KV Series. Peripheral units of the conventional KV Series such as the ladder support software "KV IncrediWare (DOS)" and "LADDER BUILDER for KV" and the handheld programmer KV-P3E(01) can be used since they are part of the Visual KV Series. However, it should be noted that the contents have changed as follows. The internal clock cycle of high-speed counters consists of three types: 1 s, 10 s, and 100 s. The time constant for an input relay specified by the HSP instruction is 10 s. The analog trimmer function is set with the Access Window built into the basic unit. The available device setting range of the TMIN instruction is from 0 to 65535. [Handheld programmer KV-P3E(01) can display 0 to 9999 .] The RUN/PROGRAM LED is displayed in the Access Window provided on the front face of the basic unit. Transistor output is not independent, but is common. With the transistor type, the output terminal layout is different. The specifications for output current of transistor outputs Nos. 500 to 502 is 100 mA. Conventional KV Series expansion units are not available as expansion units for the Visual KV Series. The channel setting switch is not provided for expansion units. Channels are determined in connection order. Scans in expansion I/O units are not synchronous with the scan time in Visual KV Series basic units. Assignment of special utility relays has partially changed. Data memory device Nos. DM1000 to DM1999 are assigned as special data memories.

Cautions when using the previous version of ladder support software

Pay strict attention to the following items when using the ladder support software. When using the ladder support software "KV IncrediWare (DOS)" or "LADDER BUILDER for KV Ver. 1.0x", set the model to "KV-300". DM0 to DM1999 are only available.

CAUTION

When the ladder support software "LADDER BUILDER for KV Ver. 1.0x" is used, do not use the monitors Change All function. If the Change All function is used, the basic unit may be damaged. Never use the Change All function.

Peripheral units and other units incompatible with the Visual KV Series
Peripheral units in the conventional KV Series and other units shown below are not compatible with the Visual KV Series. Expansion I/O units for the conventional KV Series: KV-8ER/8ET/8EX/16EX/ 8EYR/8EYT/16EYR/16EYT Analog I/O units for the conventional KV Series: KV-AD4/DA4

Cautions when Using the Serial Port

The KV-16xx/24xx/40xx units are equipped with two RJ-11 modular connectors for serial communication. When using them, pay strict attention to the following contents: Programs can be transferred and monitored using either communication port A or B. However, never connect the ladder software and a handheld programmer to the two ports at the same time. The KV-D20 operator interface panel can be connected to either communication port A or B. However, only one KV-D20 unit can be connected to a single basic unit. Never leave both the KV-D20 operator interface panel and KV-P3E(01) handheld programmer on simultaneously for a long period of time.

1.1 Before Creating Programs

This section describes what you should know before creating programs and operations for the Visual KV Series.

1.1.1 Flow from Introduction to Operation

This section describes an overview of program creation procedures, functions used, and setting items. In the example described below, a latch circuit is created as a program for the Visual KV Series. Introduction Examining contents of operations
Figure 1 shows a latch circuit which operates as follows. Pushbutton switch PB1: ON Pilot lamp (PL) turns on. Pushbutton switch PB2: OFF Pushbutton switch PB1: OFF Pilot lamp (PL) remains lit even if PB1 turns Pushbutton switch PB2: OFF OFF. Pushbutton switch PB1: OFF Pilot lamp (PL) goes out Pushbutton switch PB2: ON when PB2 is set to ON. Time chart PB1 contact PB2 contact
ON OFF ON OFF ON OFF

Fig. 1 PB1 = N.O. contact switch PB2 = N.C. contact switch

PB1 PB2

PL

Next, a program is created that will use the same operation as this circuit to control a PLC.

Program examination
Circuit 1 shows relay symbols for the latch circuit. Examine which contact in the Visual KV Series is used for each pushbutton switch and pilot lamp (Table 1). When many I/O devices are required for control, expansion units should also be considered. Circuit 1

1.1 Before Creating Programs

1.1.2 Scan Time

Scan time
The Visual KV Series repeatedly executes a ladder based on the sequence circuit as follows.
Input processing
Writes the ON/OFF status of all input terminals to the input memory before executing the program. Reads the ON/OFF status of each device (internal utility relay, timer, counter, etc.) based on the instructions, and performs arithmetic operations. Writes the arithmetic operation result to the output memory.

Program execution

Output processing

Outputs the contents of the output memory to output terminals.

The duration of time required to perform one cycle is called the scan time (or cycle time). The scan time varies based on program size and the instructions used in the program.

Input response time delay

In addition to the I/O processing time, there is also an input time delay in the Visual KV Series caused by the scan time. The input time delay is generated because the input status can only be read during the input processing time. If the input status is changed after input processing, the changed contents can only be read during the next scan time. In the figure below, 1 and 2 can be read but 3 cannot be read.

Reference: The maximum and minimum values of the input response time are as follows.
Maximum value: Input time constant + Scan time x 2 + Output response delay time Minimum value: Input time constant + Scan time + Output response delay time

Note 1: When the input time constant is made small by setting the HSP instruction, special utility relay 2813, and data memory DM1940, a signal may not be received if its ON time is shorter than the scan time. Note 2: The INT instruction is independent of the scan time. Note 3: The minimum scan time is 140 s (with the basic unit).

1.2 User Memory

1.2 User Memory

This section describes the allowable size (capacity) of a program which can be created in the Visual KV Series.

1.2.1 Program Capacity

When a user program is created for the Visual KV Series, the maximum number of steps a program can contain using the mnemonic diagram varies based on the byte count of the instructions used. The instruction byte count is determined individually for each instruction.

For more about byte counts for each instruction, refer to "2.1 Instruction List" (p.3-34).

Maximum number of lines in a program

In the KV-10xx/16xx, a program with approximately 2,000 steps can be written. In the KV-24xx/40xx, a program with approximately 4,000 steps can be written. Total byte count of the memory used by instructions 6,000 bytes / 12,000 bytes Total byte count of the memory used by objects of instructions 12,000 bytes / 24,000 bytes * In the description above, a value on the left side indicates the byte count for the KV-10xx/16xx, while a value on the right side indicates the byte count for the KV-24xx/40xx. * The memory occupied by objects indicates the memory required to execute a program when operation is started. For example, the allowable number of steps to be written can be calculated from the memory occupied by the instructions as follows. 12,000 bytes / 3 bytes (average byte count of an instruction) = 4,000 steps Note: If either the memory occupied by the instructions or the memory occupied by objects of a program exceeds the specified memory capacity, the program cannot be written or executed.

Calculating the byte count used

The byte count used in this program can be calculated as shown in the table below.

Contact No.
Contact Nos. are input/output terminal Nos. of basic units, input expansion units, output expansion units, and I/O expansion units. The contact No. is represented as a number 0 to 15.

Example In the KV-E4X, with 4 input terminals, the contact Nos. are 0 to 3. In the KVE16T(P), with 16 input terminals, the contact Nos. are 0 to 15.
In a unit with 16 or more terminals, the contact No. of the 17th terminal returns to 0 and its address No. is increased by 1.

Example In the KV-40AR, with 40 terminals (24 input and 16 output terminals), address No. 0 is assigned to input terminal Nos. 1 to 16 and address No. 1 is assigned to input terminal Nos. 17 to 24

Channel No.
The channel No. is the higher order digit in the contact No.

1.3.4 Input Relays

Input relays receive ON/OFF signals sent from external input equipment. Note 1: Input relays function as contacts in programs. They cannot be used as relay coils (outputs). Note 2: There is no restriction of the contact type (N.O. or N.C.) used, the order the relay Nos. are used, or the number of relays used.

Basic unit
Input relay time constant Though the time constant is usually 10 ms 20%, it can be changed using the following settings. When the HSP instruction is used: 10 s 20% While special utility relay 2813 remains ON, the time constant can be changed in 7 steps by setting data memory DM1940 as follows. When DM1940 is set to 0: 10s 20% 1: 20 s 20% 2: 500 s 20% 3: 1 ms 20% 4: 2.5 ms 20% 5: 5 ms 20% 6: 10 ms 20% Never set a numeric value of 7 or larger.

1 1

For more about changing the input time constant, refer to "1.4.1 Input Time Constant Change Function" (p.3-23).

Hardware input (independent of scan time) High-speed counter When the time constant is set to 10 s using the HSP instruction or data memory DM1940 (only while special utility relay 2813 remains ON), the maximum input response of input relays 0004 and 0005 of CTH0 and CTH1 becomes 30 kHz. INT instruction: 0000 to 0003 This instruction can receive any signal without regard to the scan time as far as the signal ON time is longer than the input time constant.
"HSP instruction" (p.3-86), "INT instruction" (p.3-192), "4.1 High-speed Counter Instructions" (p.3-204)

Note 1: While special utility relay 2813 remains ON, the input time constant can be specified for all input relays in a basic unit. Note 2: Never enter a number of 7 or larger to data memory DM1940. Note 3: The input time constant specified by data memory DM1940 becomes effective at the rising edge of special utility relay 2813. To change the input time constant, first change data memory DM1940, then set special utility relay 2813 to OFF and ON again. Or change the operation mode of a KV basic unit from PROGRAM to RUN. Note 4: If the HSP instruction and special utility relay 2813 are used at the same time, priority is given to the HSP instruction. Note 5: Only when a high-speed counter input or INT instruction is given, available input signals do not depend on the scan time.

1.3.5 Output Relays

Output relays output the program execution results to the outside. There are two types of outputs, relay and transistor.

Note 1: Output relays function as contacts and relay coils in programs. Note 2: There is no restriction of the contact type (N.O. or N.C.) used, the order the relay Nos. are used, or the number of relays used.

1.3.6 Internal Utility Relays

In a relay circuit, when one relay contact is used twice or more inside the circuit, a multi-pole relay with the same number of poles as the number used may be needed. Internal utility relays function only in programs, and eliminate the complexity of relay circuits to facilitate circuit design. Note 1: Internal utility relays function as contacts and relay coils in programs. Note 2: There is no restriction of the contact type (N.O. or N.C.) used, the order the relay Nos. are used, or the number of relays used.

Retentive function of internal utility relays

Except for internal utility relays, all relays turn OFF when the operation mode is changed or when operation is stopped via a power shutdown. When operation is restarted, all relays remain OFF except relays whose input condition is ON. However, internal utility relays can be set using the MEMSW (memory switch) whether or not they are to be retained. (Internal utility relays 2700 to 2715, however, are always retained.) When an internal utility relay is set to be retained, its ON/OFF status is stored even if the power is turned off. By using the retained relay all clear function (FUN65), all relays which are set to be retained can be set to OFF.

For more about setting the memory switch, refer to "MEMSW instruction" (p.3-92).

1 1

Application example of a retentive function: Lift vertical movement control Internal utility relays 1000 and 1001 are set to be retained. When the upper/lower limit switch turns ON, the direction of lift movement is inverted. Even if the power is turned off while the lift is moving up (or down), the lift continues to move up (or down) when the power is turned on again.

1.3.7 Special Utility Relays

Each special utility relay has a unique function. By using special utility relays effectively, programs can be simplified and program control improved. Note 1: A special utility relay can be used as many times as desired in one program. Note 2: Special utility relays dedicated for reading can be used as contacts, but cannot be used as outputs.
For more about relays dedicated for reading, refer to "1.3.8 Special Utility Relay List" (p.3-14).

Description
Relay 2002: Always ON By setting an output relay to ON using relay 2002, the output relay can be used as a "running indicator output".
2002 2002 HSP 0100 00000 LDA DM0000 STA

Set the input time constant of relay 0100 to 10 s. Transfer the ON/OFF status data of channel 0000 to DM0000.

Relay 2003: Always OFF. Opposite that of relay 2002, use relay 2003 where it is not required to be turned on. For example, when using only the up function of an up/down counter, use relay 2003 in the DW (down) input. Relays 2004, 2005 and 2006: Clock pulse For each relay, the time ratio is "ON:OFF = 1:1". (Accordingly, the ON time of relay 2005 is 0.05 sec/pulse.) However, because these relays depend on the scan time, error as much as the scan time is generated. By combining an output relay, an "intermittent output" can be made. By using relay 2006 as input for a counter, the counter can be used as a longterm timer.
1000 C000 #03600 C000 2006 1000

1000 turns ON at every hour.

Relay 2007: Remains OFF during only one scan when operation is started. This relay can be used when a signal needs to be sent after a specific period (equivalent to one scan) after operation is started. This relay can also be used for an initial reset at the start of operation. After one scan, this relay remains ON.
1000 2007 #00100 C005 0000

When operation is started, this relay returns the current value of C005 to 0.

Relay 2008: Remains ON during only one scan when operation is started. This relay can be used for an initial reset at the start of operation. After one scan, this relay remains OFF.
0000 1000 2008 RES SFT D 1100 CLK 1100

When operation is started, this relay sets all internal utility relays used by the SFT instruction to OFF.

2008

#00000 LDA DM0000 STA

When operation is started, this relay returns the current value of DM0000 to 0.

Relay 2813: Sets the input time constant of the CPU. While relay 2813 remains ON, the input time constant of a basic unit can be set using the value of DM1940.

1.3.9 Timers and Counters

Timers and counters can be set in a program, and their outputs can be used as contacts elsewhere in the program. [There is no restriction on the contact type (N.O. or N.C.) and the order of use.] A same number can be assigned to only one timer or counter. For example, T005 and C005 cannot be used in the same program.

Description

Timers When 0.1-s timers (TMR) and high-speed 0.001-s timers (TMS) are used as contacts, the "Tnnn" No. is used for both types. However, the form for setting is different. "TMRnnn#ddddd" is used for 0.1-s timers, "TMHnnn#ddddd" is used for high-speed 0.01-s timers, and "TMSnnn#ddddd" is used for high-speed 1-ms timers (nnn = timer No, ddddd = timer set value). In a single program, different timer Nos. must be assigned to each of TMRnnn, TMHnnn, and TMSnnn. When the PLC is stopped, all timers are reset and their current values become equivalent to set values.

Counters When counters (C) and up/down counters (UDC) are used as contacts, the "Cnnn" No. is used for both types. However, the form for setting is different. "Cnnn#ddddd" is used for counters, while "UDCnnn#ddddd" is used for up/down counters.

In one program, different numbers must be assigned to each of the counters and up/down counters. Even when operation is stopped, each counter stores whatever value it has at that time.
"TMR instruction" (p.3-67), "TMH instruction" (p.3-68), "TMS instruction" (p.3-69), "C instruction" (p.372), "UDC instruction" (p.3-76).

High-speed counters and high-speed counter comparators The Visual KV Se ries is equipped with two high-speed counters (CTH0 and CTH1) and four high-speed counter comparators (CTC0, CTC1, CTC2, and CTC3) with a 30-kHz input response speed (frequency), two phases, and size of 16 or 24 bits. Note: When a high-speed counter or high-speed counter comparator will be used as a 24-bit device, a set value is required to be stored in a data memory using the MEMSW instruction.

For details about high-speed counters and high-speed counter comparators, refer to "Chapter 4 Highspeed Counters" (p.3-203).

1.4 Special Functions

This section describes special functions to set and confirm operations on the Visual KV Series, and useful functions for program debugging and adjustment of external equipment.

1.4.1 Input Time Constant Change Function

The input time constant can be changed when a signal is read from an input contact. When connecting external equipment which has no contact in which chattering such as transistor outputs does not occur, and inputting pulses of short width, the input time constant change function can be used to decrease the input time constant.

Setting the input time constant for basic units using special utility relays
The input time constant for a basic unit can be changed using data memory DM1940 and special utility relay 2813. Though the input time constant is usually 10 ms, it can be changed to a value that corresponds to the number stored in DM1940 by setting special utility relay 2813 to ON. If the HSP instruction and special utility relay 2813 are used at the same time, priority is given to the HSP instruction and the number stored in DM1940 is ignored. Special utility relay 2813 OFF: Sets the input time constant to 10 ms. ON: Refers to the number stored in DM1940, then determines the input time constant.
Number stored in DM1940 0 1 2 3 4 5 6 7 or more Input time constant 10 s 20 s 500 s 1 ms 2.5 ms 5 ms 10 ms Not allowed

1 1

Note 1: Be sure to set the input time constant to 10 s when using the 30-kHz high-speed counter input. Note 2: Never enter a number that is 7 or larger to data memory DM1940. Note 3: The input time constant specified by data memory DM1940 becomes effective at the rising edge of special utility relay 2813. To change the input time constant, first change data memory DM1940, then set special utility relay to OFF and ON again. Or change the operation mode of the KV basic unit from PROGRAM to RUN. Note 4: The input time constant for input relays set by the HSP instruction is 10 s.

For more about the HSP instruction, refer to "HSP instruction" (p.3-86). For more about setting the input time constant for expansion units, refer to "Input time constant for expansion units" (p.1-76). Note 5: Set the special utility relay using the SET/RES instructions.
Note 6: When the input time constant is set to 1 ms or less, connect the output equipment without contacts. If connecting output equipment with contacts, contact bounds may enter. Note 7: Except for interrupts and high-speed counters, signals whose ON time is shorter than the scan time may not be received even if the input time constant is set to a small value.

1.4.3 Constant Scan Time Mode

This function executes a program while keeping the scan time at a constant value which usually changes based on the processing contents. This section describes how to set this function. Though the scan time changes usually depending on the processing contents, it can be kept at a constant value by using this function. This function can be used to acquire data from external equipment at a constant time interval. The set value should be longer than the maximum scan time because the scan time is kept at a constant value until the end of processing. Setting procedure Set the desired scan time to temporary data memory TM29. Set special utility relay 2303 to ON. The scan time is written to TM31. The scan time can be set in 1-ms increments. Enter the desired scan time (ms) to the temporary data memory. Setting example In this example, the scan time is kept at 20 ms.

Setting procedure When special utility relay 2300 turns ON, all outputs from all output relays (0500 to 0915) to the outside are cleared after 1 scan is finished. However, the display in the Access Window and the output indicator lamps are not cleared. Setting example By setting/resetting special utility relay 2300 using the Access Window, the "KV IncrediWare (DOS)" or "LADDER BUILDER for KV" programming support software, or the KV-P3E(01) handheld programmer, the external output prohibition function can be used. External outputs are prohibited while input 0000 is ON. External outputs are permitted, though, while input 0000 is OFF.

1.4.5 Input Refresh Disabled Function

This function disables the update of inputs from each unit triggered by input signals from external equipment. By disabling external input refresh, inputs from each unit can be set to ON/OFF in monitor status without mechanical operations to enable a program check. Setting procedure When special utility relay 2301 turns ON, input refresh (read of input relays) for all input relays (0000 to 0415 used by the QL Series) is skipped. In this status, inputs can be set to ON/OFF from the Access Window, the "KV IncrediWare (DOS)" or "LADDER BUILDER for KV" programming support software, or the KV-P3E(01) handheld programmer. Setting example By setting/resetting special utility relay 2301 using the Access Window, the "KV IncrediWare (DOS)" or "LADDER BUILDER for KV" programming support software, or the KV-P3E(01) handheld programmer, the external input refresh prohibition function can be used. External input refresh is prohibited while input 0000 is ON. External input refresh is permitted, though, while input 0000 is OFF.

Note 1: The set value for the constant scan time must be greater than the actual scan time. Otherwise, special utility relay 2304 turns on during every scan to disable constant scan time mode. Note 2: If the scan time exceeds the set value, special utility relay no. 2304 turns on during the next scan.

Output Disabled Function

During checking of a program, this function clears output from output relays regardless of the program currently running. Setting Turn on special utility relay No. 2300. After one scan is completed, all output relays (00500 to 00503, 07500 to 17915) are cleared.

Example Use the output disabled function by executing FORCED RESET/RESET to special utility relay No. 2300 from the monitor display.

To execute FORCED RESET or RESET, refer to "Chapter 6 Handheld Programmer" (p.1-195).

In a conventional ladder diagram, output instructions can be written only on the right side of a ladder diagram. On the other hand, in an extended ladder diagram, output instructions can be written anywhere except on the left. As the result, the programs shown below can be written.

1.5.2 Advantages of Extended Ladder Diagrams

The number of lines in a ladder diagram can be reduced. Because both output instructions and input instructions can be written side by side, the number of program lines can be reduced. As the result, the contents of the program can be seen at a glance.

In a conventional ladder diagram, operations performed by the program cannot be easily understood. In an extended ladder diagram, operations performed by the program can be understood at a glance.

Processing sequence is clear. Ladder symbols can be laid out in processing sequence, so the program flow is easier to understand. In addition, maintainability is considerably improved.

Example When the start switch is set to ON, a lamp is lit for three seconds, a buzzer is sounded for two seconds, and then the motor starts to rotate.

When the start switch (0000) is set to ON, a lamp (0500) is lit and timer 0 is activated. When timer 0 turns ON three seconds later, the lamp goes out, a buzzer (0501) is sounded, and timer 1 is activated. When timer 1 turns ON two seconds later, the buzzer is stopped and the motor (0502) starts to rotate. When the start switch (0000) is set to OFF, the motor is stopped and all operations are reset.

By using an extended ladder diagram as shown above, the program can be executed in the sequence of the processing to be performed. So even a person who uses a relay sequence for the first time can understand the processing contents. By combining the STG instruction, double coils can also be used.

At the rising edge of input 0001, 1002 turns ON. At the rising edge of input 1003, 1002 turns ON. If input 0000 is ON, 1000 turns ON.

Input 0000 Input 0001 Input 0002 Output 0500 turns ON. turns ON. turns ON. turns ON.

If 1000 is ON, 1001 turns ON.

When 1001 turns ON, output 0500 turns ON.

Because the program can be written in only one line when an extended adder diagram is used, it is easier to look at and understand compared with a program written using a conventional ladder diagram.

Description
Output relay 0500 remains ON after input relay 0000 turns OFF. Output relay 0500 turns OFF when input relay 0001 turns ON. SET instruction sets a latch whereas RES instruction resets it. RES instruction not only turns OFF relay coils but serves as a reset signal when a timer or counter is used as an operand.

Note Describes the notes for the instruction. Tips Describes hands-on techniques for efficient programming. Operand Shows operands (element Nos.) that can be used for the instruction. Key operation Describes the basic key operations on the handheld programmer. Set the mode switch to PROGRAM.

Note: The SET and RES instructions can be entered in any order. Note, however, that priority is given to the instruction that is entered last. In the above example, when both 0000 and 0001 are ON, RES has priority over SET, causing 0500 to remain OFF.

Tips
Differences between SET/RES and KEEP Basically , SET/RES and KEEP ( p. 3-57 and p. 3-71) serve the same purpose. SET and RES can be used separately. Therefore, RES can be placed before SET. Another instruction may be placed between SET and RES. KEEP needs only three lines of program, therefore saving memory space when used a number of times.

Description
Output relay 0500 remains ON after input relay 0000 turns OFF. Output relay 0500 turns OFF when input relay 0001 turns ON. SET instruction sets a latch whereas RES instruction resets it. RES instruction not only turns OFF relay coils but serves as a reset signal when a timer or counter is used as an operand.

Note: The SET and RES instructions can be entered in any order. Note, however, that priority is given to the instruction that is entered last. In the above example, when both 0000 and 0001 are ON, RES has priority over SET, causing 0500 to remain OFF.

Tips
Differences between SET/RES and KEEP Basically , SET/RES and KEEP ( See above and p. 3-80) serve the same purpose. SET and RES can be used separately. Therefore, RES can be placed before SET. Another instruction may be placed between SET and RES. KEEP needs only three lines of program, therefore saving memory space when used a number of times.

0500 and 0501 turn ON 1 second and 3.5 seconds respectively after 0000 turns ON. TMR000 is a subtraction timer. When the current value reaches "#00000", contact T000 turns ON, and then output relay 0500 turns ON. When input relay 0000 turns OFF, contact T000 and T001 turn OFF and the current values of TMR000 and TMR001 are reset.

Note 1: The TMR number cannot be the same as any other TMS, TMH, TMR, C, or UDC instructions in the same program. Note 2: The current value of TMR is not retained but is reset to the preset value if a power failure occurs or if power is turned OFF.

Tips
When the number specified by TMR is used as a contact (T000 in the above example), this contact can be used as many times as desired. It can also be used as both N.O. and N.C. contacts. Timer accuracy = 0.1 sec. + (1 scan time) (max.)

Description
The counter performs one counting at the rising edge of clock pulse. When the current value reaches the preset value, the coil of specified No. turns ON. When a reset input (b [N.C.] contact) turns ON, the current counter value is reset to "00000". Since C is software counter which is set on the program, the response speed depends on the scan time.

Note 1: When a reset input is provided using an a (N.O.) contact, the current counter value is reset at power-off. Note 2: The C number cannot be the same as any other TMS, TMH, TMR, C, or UDC instructions in the same program. Note 3: The current C value is stored more than two months (KV-10xx: More than 20 days) at 25C even when the KV is not in operation or is turned off.

Tips
By entering relay 2007 (which can turn the counter OFF for only the first scan time when the operation is started) using an 'a' (N.O.) contact in series as the input relay for resetting counter, you can reset the current C value whenever the operation is started.

When SET input relay No. 0001 is ON and RESET input relay No. 0002 is OFF, 0500 turns ON. When RES input (0002) is ON, output relay 0500 turns OFF. When both 0001 and 0002 are OFF, the previous status is retained.

Note 1: When 0500 used for KEEP instruction in the above example is changed to 0500 OUT instruction ( ), it forms a double coil. In such a case, priority is given to the instruction that is entered last "Double coil" (p. 3-65) Note 2: When both 0001 and 0002 are ON, RESET (0002) has priority over SET (0001), causing 0500 to turn OFF.

2.4 Instruction Details

Application of KEEP instruction

Detection of chewing gum packs Detects chewing gum packs over the carton using the proximity switch ES series (0001 to 0003). If the switch detects that one or more packs of chewing gum are missing, output relay 0500 turns ON for 1 s. The timing clock is generated from the visible beam photoelectric switch PZ2 (0000). Executes SET when all input relays 0000 to 0003 are ON. Detects presence/absence of chewing gum packs at DOWN edge of 0000. Outputs 1-s one-shot pulse from output relay 0500 when 1000 is OFF.

Description
First relay No. 1000 turns ON (OFF) when the data input relay is ON (OFF) at the rising edge of the clock pulse. Clock pulse A) shifts the ON status of input relay 0001 to relay 1000, and shifts the status of other relays in sequence as shown in A) on the right. When the data input is OFF as for clock pulse E), OFF status is shifted to relay 1000. When the RESET input relay turns ON, all the relays (from the first one to the last one) turn OFF. Several SFT instructions can be used in a program.

Details of W-ON and W-UE Instructions

A combination of W-ON, W-OFF, W-UE, and W-DE instructions is much more effective when used in programs controlling sequential operation where the completion of one operational step starts the next step. This section describes minute differences in the operation of these instructions. Difference between W-ON and W-UE

Note: An input operand relay No. for these instructions can be duplicated in a program, but output operand relay Nos. cannot be duplicated. As shown above, W-UE requires a certain order for turning ON relays 0000 and 0001, but W-ON does not. Therefore, W-UE is suitable for circuits to be executed at every input; W-ON is suitable for circuits that go on to the next operation when a certain condition is satisfied. The operation of W-OFF and W-DE instructions are same as above by the operation which turns relays OFF.

2.4 Instruction Details

Details of STG instruction

STG instruction The STG instruction is suitable for sequential step-by-step processing. The whole process is divided into several operational steps, and one program is assigned to each step. The process to turn on several lamps sequentially can be divided into the following five steps: 1) 2) 3) 4) 5) Wait until the start switch is turned ON. Turn on lamp 1 for 1 second. Turn on lamp 2 for 3 second. Turn on lamp 3 for 5 second. Turn on lamps 1, 2, and 3 simultaneously for 7 seconds.

These five steps are sequentially performed in order as shown in the flowchart below. If a ladder program is written for such sequential processing without any STG instructions, the resulting program may be complicated and difficult to review by others.
Sequential processing Start
Start SW ON?
YES Turn on lamp 1 for 1 second.

NO

Turn on lamp 2 for 3 second. Turn on lamp 3 for 5 second.

Turn on lamps 1, 2, and 3 simultaneously for 7 seconds.

I/O assignments Assign the input and output of the Visual KV Series as follows: 1) 2) 3) 4) Start switch: Turned on when 0000 turns ON. Lamp 1: Lights when 0500 turns ON. Lamp 2: Lights when 0501 turns ON. Lamp 3: Lights when 0502 turns ON.

Note: The double coils in different STG instruction blocks operate properly. However, when several STG instructions turn ON simultaneously, priority is given to the one programmed last. Conditional branching When input relay 0000 (start SW) turns ON, output relay 0500 turns ON. Then, as programmed for conditional branching, output relay 0501 turns on for 1 second when 0001 turns ON, and 0502 turns ON for 2 seconds when 0002 turns ON. After each operation is completed, the program returns to the conditional branch and repeats the same steps.

Description

When 1000 is ON, 0500 turns ON/OFF as soon as 0001 turns ON/OFF. When 1000 is OFF, 0500 remains OFF after 0001 turns ON. When 0001 and 0500 are ON, 0500 remains ON after 0001 turns OFF. The program step specified with STP-STE instructions are executed when the STP operand relay is ON. When the operand relay is OFF, the program execution jumps to STE instruction. (Fig 1). STP-STE instructions can be nested up to 8 levels deep as shown in Fig. 2. When 1000 is OFF, steps 1) through 3) are not executed. Control jumps to the STE instruction just above step 4), then step 4) is executed. When 1000 and 1001 are ON, steps 1) through 3) are executed in that order. When 1000 is ON and 1001 is OFF, steps 1), 3), and 4) are executed in that order, while step 2) is left unexecuted.

Measures pulse-to-pulse interval or pulse width for input relay 0000. ITVL instruction has two functions: Measures pulse-to-pulse interval (cycle) or pulse width. (Minimum unit: 10 ms) Obtains the average of the contents of data memory. Each input has the following functions: PLS Executes measurement. In data memory measurement, however, PLS input is disabled in modes 0006 to 1999. Values are fetched only at the scan when PLS input is ON in modes 10000 to 11999. The measured value is written into the specified data memory (DM). In the above example, the measured value of input relay 0000 is written into DM0004 (DM0000 + 4 addresses). PAUSE Pauses the measurement when turned ON. RES Initializes the contents of data memory (DM) when turned ON. In the above example, DM0004 to DM0015 are reset to "#00000". DM0000 to DM0003 are designated as the area to write the initial setting.

Description
When input relay 0000 turns ON, the subroutine specified by SBN00 and RET is executed. When the subroutine ends, instructions following CALL are executed. When the input relay is ON, the CALL instruction executes the subroutine specified by the operand. A subroutine program must be defined between the SBN and RET instructions. A subroutine must be defined between END and ENDH instructions. Once a CALL instruction has been encountered, program execution transfers to the subroutine specified by the SBN and RET instructions. Once a RET instruction has been encountered, program execution returns to the instruction immediately following the CALL instruction.

Description
Use FOR-NEXT instructions in a subroutine program (between SBN and RET) to initialize data memory (DM0100 through DM0149) when the operation is started. The indirect addressing method is used to change the data memory, so the initialization is completed when the TM02 value becomes "50 + 1" between the FOR and NEXT instructions.

"Indirect addressing" (p. 3-127)

The FOR instruction takes either of the following two types of operands: the number of repetitions or the location (DM No.) of the data memory containing the number of repetitions. Define the program to be repeated between the FOR and NEXT instructions. The FOR instruction repeats the desired sequence by the specified number of times during each scan time.

FOR / NEXT

2.4 Instruction Details

Tips
Note 1: The FOR-NEXT instruction pair repeats the program for a specified time period at each scan. It usually is used in steps or subroutines. Note 2: When a large number of loops or long programs are defined between FOR and NEXT instructions, the processing time for one scan may become too long, resulting in "Cycle time error". In such a case, reduce the number of loops or shorten the ladder program. The FOR-NEXT instruction set can be nested up to 8 levels deep. Nine or more nested levels will result in a FOR-NEXT error.
FOR #05 FOR #02 FOR #05 NEXT NEXT NEXT

1) 2) 3)

After repeating FOR-NEXT 3) five times, program execution transfers to the instructions following the NEXT instruction. FOR-NEXT 2) is repeated twice while FOR-NEXT 3) is executed once. Thus, FOR-NEXT 2) is executed 10 times. FOR-NEXT 1) is repeated 5 times while FOR-NEXT 2) is executed once. Thus, FOR-NEXT 1) is executed up to 50 (5 x 2 x 5) times.

Indirect addressing
Indirect addressing Indirect addressing is used to so you don't have to use fixed data memories or relay Nos. when the contents of data memory or a relay is stored in internal registers, or when the contents of the internal memory is stored in data memory or a relay. Method for indirect addressing Specify the operand for instructions as "#TMxx". The contents of "TMxx" is considered to be the specification No. (indirect addressing).

Example When TM02 value is "0000", "#TM02" represents DM0000. When TM02 value is "10000", "#TM02" represents 0000 (relay).
Any of "02" through "29" can be specified for "xx". Specify the desired decimal number for "xx". Numbers "0000" through "1999" specify DM0000 through DM1999 (data memory). Numbers "10000" through "27915" specify 0000 through 17915 (relay).

Example: LDA #TM15

TM15 value 20 11000 Data entered into internal register DM0020 1000 to 1015

This is the same operation whether "LDA DM0020" or "LDA 1000" is specified. The specified data memory or relay can be changed as desired by changing the value of TM15. Example: STA #TM02
TM02 value 00 13000 Specified destination DM0000 3000 to 3015

1 2

This is the same operation whether "STA DM0000" or "STA 3000" is specified. The specified data memory or relay can be changed as desired by changing the value of TM02. Range of DM and relay Nos. that can be specified by "TMxx"
TMxx value 0000 to 1999 2000 to 9999 10000 to 27915 DM/relay DM0000 to DM1999 Cannot be used. 0000 to 17915

Instructions which can use indirect addressing: Specify "#TMxx" as an operand relay. LDA, @LDA, STA, @STA, CMP, @CMP, ADD, @ADD, SUB, @SUB, MUL, @MUL, DIV, @DIV, ANDA, @ANDA, ORA, @ORA, EORA, @EORA Note 1: "2000" to "9999" cannot be used as a TMxx value.

Description

When input relay 0005 turns ON, the operand hexadecimal key data is read. HKEY instruction employs four inputs and four outputs arranged as shown below.

Pressing two or more keys simultaneously is invalid.

Pressing two or more keys simultaneously is OK. (With diode)

The HKEY instruction employs four input relays and four output relays from the specified number. Inputs are processed on a time-sharing basis, so that input processing requires 8 scan time cycles (approx. 160 msec when the scan time is 20 msec or less). When a hexadecimal key is pressed, the HKEY instruction turns ON the corresponding special utility relay (2900 to 2915).
Relay No. 2900 Hex key 0 2901 1 2902 2 2903 3 2904 4 2905 5 2906 6 2907 7 2908 8 2909 9 2910 A 2911 B 2912 C 2913 D 2914 E 2915 F

The special utility relay status indicates whether two or more keys can be pressed simultaneously or whether a key input read operation has completed, as shown in the following table:
Relay No. Status
R: Reading

2814 R/W ON: Pressing two or more keys simultaneously is not valid.
W: Writing

2815 R ON: Key input read operation has completed.

Note 1: An HKEY instruction can be defined only once in a program. Note 2: The HKEY instruction turns output relays ON/OFF every scan time. Connect the device with transistor output. Note 3: If the scan time is shorter than 8 ms, set the input time constant smaller than the scan time.

Note 4: When two or more keys are pressed simultaneously even once during the scan while relay 2814 is ON, relays 2900 through 2915 keep the current status as soon as relay 2815 turns ON. Note 5: The HKEY instruction does not properly operate if the scan time is longer than 200 ms. Note 6: When the expansion I/O module is used as an operand, the fetch may fail unless the scan time is fixed to 2 ms or longer.

KV executes all arithmetic instructions (i.e. data exchange) by using an internal register, in order to increase the processing speed. This section begins by describing details of the internal register. Internal register An internal register stores 16-digit binary data. That is, the resister uses 16 bits for storing ON-OFF status data (1-0 status data). The internal register is required when the KV performs arithmetic operation. Because this is not an instruction nor operand, it is not necessary to take into consideration how the internal register functions or operates.

Data memory accessed in indirect addressing via temporary memory

1. ON-OFF status of the specified relay and 15 successive relays is stored into the resister. 2. Current T/C value (decimal value = #*****) is automatically converted into a binary value and input to the internal register. 3. Constant (decimal value = #*****, hexadecimal value = $****) is automatically converted into a binary value and input to the internal register. 4. The range of numbers that can be specified is as follows: Decimal #00000 to #65535 Hexadecimal $0000 to $FFFF The constants can be entered by using #,@$ and the corresponding alphanumeric keys. (Pressing #,@$ once allows you to enter decimal values, and pressing twice to enter hexadecimal values.) 5. The contents of the internal register (binary) is automatically converted into a decimal value and (#*****) input to a timer/counter as the preset value. Note 1: The internal structure of the internal register is the same as that of the data memories. Although the data memories can store data when the power is being OFF, the internal register cannot do so. Note 2: Even for running one program, the contents of the internal register is rewritten each time when an instruction is executed. Note 3: The internal register cannot be monitored.

Binary number

The LDA instruction transfers the input (ON/OFF status) of the KV basic unit to the internal register using binary numbers. The STA instruction outputs the binary data in the internal register as the ON/ OFF status from the KV-E16T(P) (output unit).
Refer to "1.3 Device Configuration" (p. 3-5) for relay number assignments.

Note 1: When "LDA 0004" and "STA 0604" are programmed in the above example, the LDA instruction can transfer inputs 0100 through 0103 to the internal register; however, the STA instruction cannot output data across the channels. As a result, the ON/OFF status of inputs 0100 through 0103 cannot be output even if they are fetched by the LDA instruction. Note 2: Relays 0000 through 0415 are assigned as input relays, and 0500 through 0915 are assigned as output relays.

In example a), the LDA instruction reads the ON/OFF status of input relays 0000 through 0015 to the internal register. "ANDA $00FF" instruction is used to leave only the digital switch input (2 digits). BCD data is then converted into BIN (binary) data. (BIN is used in the KV series.) The contents of the internal register is input as the setting value of C001. In example b), the current value of counter C001 is read and output to output relays 0500 through 0515.

Note 1: An LDA instruction can read the current value of a counter or a timer, but cannot read the setting value. Note 2: An STA instruction can change the setting value of a counter or a timer, but cannot change the current value.

Description
The ADD instruction adds the operand value to the contents of the internal register and inputs the result back to the internal register. In the above example, "#00100" is added to the contents of DM0000 and the result is stored in DM0001. When the contents of DM0000 is "#00100", for example, "#00200" is stored in DM0001. DM0000 (#00100) + #00100 DM0001(#00200)

Note 1: An overflow occurs when the operation result exceeds 16 bits ($FFFF, #65535). In such a case, only the data of the low-order 16 bits is input back to the internal register. For example, when the contents of the internal register is "$FFFF" and the operand is "$0001", the result will overflow. Note 2: When an overflow occurs, special utility relay 2009 turns ON.

No change Turns ON when all 32 bits are "0" after a DIV operation. Turns OFF at other times. No change Turns ON when the divisor of a DIV operation is "0" or the DM or relay indirectly addressed with #TM is out of range.

"Indirect addressing" (p. 3-127)

Description
The 32-bit value (binary) consisting of the higher 16 bits from TM00 and lower 16 bits from the internal register is divided by the value specified by the operand. The higher 16 bits of the result is input back to TM00 and lower 16 bits to the same internal register. The remainder is stored in TM01.

The operation result is written into DM0011. The contents of D15 are shifted to carry bit 2009. In the above example, the contents shift to the left by the operand value (10) every scan time while input relay 0001 is ON. Use @SLA, a differentiation type instruction, to execute the instruction only once when input relay 0001 turns ON.

As the example of the INC instruction shows, using different instructions sometimes simplifies the program even for the same control. Simpler programming reduces the time for debugging. It is convenient to use the CMP instruction for comparator outputs. OR instruction Compare the following two programs. With program 1), input relays 0000 through 0004 are individually counted even when they turn ON simultaneously. With program 2), when some input relays 0000 through 0004 turn ON simultaneously, duplicated inputs are ignored. Use the appropriate program according to your application.

Description
Operation with the MPX instruction When input relay 0000 is ON, the ON/OFF status of input relays 0000 through 0015 is transferred to the internal register. The section of the internal register specified by the operand (input relays 0004 through 007: 4 bits) is converted into a hexadecimal number (0 to F). Only the bit at the position specified by the hexadecimal number is set to "1" and other bits are set to "0". The resulting ON/OFF status is input back to the internal register, and then output to inputs 1000 to 1015. In the example, when the value specified by inputs 0004 to 0007 are converted into "A", internal relay 1010 turns ON.

Operation with the DMX instruction When input relay 0001 is ON, the ON/OFF status of input relays 0100 through 0115 is sent to the internal register. Within the 16-bit data of the internal register, the number corresponding to the position of the most significant bit with "1" (0 to F) is converted into 4-bit data and input back to the internal register. The contents of the internal register are then transferred to DM0000. In the example, when input relay 0114 turns ON, "E" is input to DM0000.
Most significant bit with "1"

The DMX instruction is disabled when all bits in the internal register are OFF. In such a case, special utility relay 2012 turns ON.

Application of MPX and DMX instructions

MPX instruction Connect the one-digit data of a BIN digital switch to input relays 0004 through 0007. Connect output relays 0500 through 0515 to lamps 0 to 15. An operator turns on the lamp corresponding to the digital switch using binary numbers.

6 . When the following program is entered with the programming support software and sent to the KV, and then read from the KV with the software, reading is disabled due to a "Reverse Compilation Error". When a return is included in parallel connection in a ladder program, a decompilation (reverse compilation) error is generated as shown below. To prevent this error, change the ladder diagram to eliminate the return, or separate the parallel connection.

Description
When 1000 is ON, execution of interrupt is enabled. When 1000 is OFF, execution of interrupt is disabled. Interrupts are enabled between EI instruction and DI instruction. Once an EI instruction is executed, an interrupt is enabled until a DI instruction is executed. Any interrupt is disabled when the Visual KV Series starts operation. The DI instruction disables execution of an interrupt. Use this instruction to temporarily disable an interrupt. The EI instruction enables execution of an interrupt. Use this instruction to release an interrupt that was disabled by a DI instruction. To execute another interrupt during execution of the previous interrupt, include EI instruction in this first interrupt. EI-DI instruction set can be nested to four levels.

Note 1: When any interrupt occurs between DI and EI instructions (interrupt disabled period), the disabled interrupt is stored (to 8 levels max.). The stored interrupt is executed as soon as an EI instruction is executed. Note 2: If an INT CTC instruction is stored before a RES CTC instruction is executed, the stored INT CTC is deleted.

3.2 Interrupt Processing

This section describes interrupt processing.

Visual KV Series

3.2.1 Interrupt Processing

Outline
Normally, a PLC processes a ladder sequence program by repeating the steps of input processing, program execution, and output processing. Therefore, signals which are shorter than the scan time cannot be received. When the interrupt processing function is used, a process can be executed at the instant of the interrupt, independent of the scan time. When any interrupt occurs, the Visual KV series suspends the currently executed program and executes the interrupt program in accordance with the interrupt factor. When the interrupt program completes, the Visual KV resumes execution of the suspended program.

For more about scan time, refer to "1.1.2 Scan Time" (p. 3-3).

Return to the next line of the interrupt. Output processing

Direct output
(0500 to 0503)

Direct input/output
The direct input/output functions are used during interrupt processing. Direct input allows the KV PLC to fetch the input status of input relays 0000 through 0015 (KV10xx: 0000-0005, KV-16xx: 0000-0009) during execution of the interrupt program. Direct output allows the Visual KV PLC to output the ON/OFF status of output relays 0500 through 0503 during execution of the interrupt program. No special setting is required to use the direct input/output functions. The functions can be used only by using the devices assigned for direct input/output within the interrupt program.

Executing interrupts
The INT (Interrupt) instruction is used to execute an interrupt. Since an interrupt is disabled at the start of operation, it is necessary to execute an EI (Interrupt enable) instruction before using the INT instruction. In addition, the input time constant should be set shorter by using the HSP instruction (to 10 s) or by specifying the desired value in DM1940 and turning ON special utility relay 2813.

For more about the input time constant, refer to "1.4.1 Input Time Constant Change Function" (p. 323).

3.2 Interrupt Processing

3.2.2 Types of Interrupts

Interrupts can be divided into two types: an interrupt by an external input, and an interrupt by the high-speed counter comparator. This section describes both of these interrupt types. Interrupt by an external input This interrupt is executed by input relays 0000 through 0003. Use the special utility relay to specify the polarity of the interrupt factor to a rising or falling edge. Interrupt by the high-speed counter comparator This interrupt is executed when the current value of the high-speed counter (CTH) matches the preset value of the high-speed counter comparator (CTC).

Polarity setting for interrupts by an external input

Turn ON the appropriate special utility relay to specify the interrupt factor to a rising or falling edge. The interrupt polarity can be changed as follows by setting special utility relays 2402/2403 (INT0), 2404/2405 (INT1), 2410/2411 (INT2), and 2412/2413 (INT3).
Interrupt type Relay No. Status OFF INT0 2402 ON OFF ON OFF INT1 2404 ON OFF ON OFF INT2 2410 ON OFF ON OFF INT3 2412 ON OFF ON 2413 2411 2405 2403 Relay No. Status OFF OFF ON ON OFF OFF ON ON OFF OFF ON ON OFF OFF ON ON Description Interrupt occurs at rising edge. Interrupt occurs at falling edge. Interrupt occurs at both rising and falling edges. Interrupt occurs at rising edge. Interrupt occurs at falling edge. Interrupt occurs at both rising and falling edges. Interrupt occurs at rising edge. Interrupt occurs at falling edge. Interrupt occurs at both rising and falling edges. Interrupt occurs at rising edge. Interrupt occurs at falling edge. Interrupt occurs at both rising and falling edges.

CAUTION

Use SET-RES instructions to turn the special utility relays ON/OFF.

Input capture
Each external interrupt factor is provided with the input capture function. This is a function which writes the value of the high-speed counter into the data memory when an interrupt occurs. Without any particular settings, the value of the highspeed counter is automatically transferred to DM1928 through DM1935 when an interrupt occurs.
External interrupt factor Occurrence of INT0 Occurrence of INT1 Occurrence of INT2 Occurrence of INT3 Description Value of CTH0 is written to DM1928 (low-order bits) and DM1929 (high-order bits) Value of CTH0 is written to DM1930 (low-order bits) and DM1931 (high-order bits) Value of CTH1 is written to DM1932 (low-order bits) and DM1933 (high-order bits) Value of CTH1 is written to DM1934 (low-order bits) and DM1935 (high-order bits)

3.2 Interrupt Processing

CAUTION

Use SET-RES instructions to turn the special utility relays ON/OFF. The input capture function stores the high-order bit data only when the 24bit high-speed counter is used. The data is undefined when the 16-bit highspeed counter is used.
"4.4.1 24-bit High-speed Counter" (p. 3-221)

Visual KV Series

Timing of the input capture execution depends on the input polarity setting specified with special utility relays 2402 through 2405 and 2410 through 2413.

3.2.3 Interrupt Priority

When many interrupts occur sequentially, priority is given to the interrupt which occurs earlier. When two or more interrupts occur simultaneously, priority is given in the order of 0000, 0001, 0002, 0003, CTC2, CTC3, CTC0, and CTC1. Note 1: While one interrupt is being executed, other interrupts are disabled. (Multilevel interrupts are possible by placing an EI instruction within an interrupt routine.) Note 2: When other interrupts occur during execution of an interrupt, other interrupts are stored up to 8 levels deep. The stored interrupts are executed after completion of the previous interrupt, according to the priority order. However, an interrupt which uses the same device as a previous interrupt cannot be stored.

3.2.4 Interrupt Program 3

The interrupt program is a program which is executed by an interrupt. It is necessary to execute an EI (Interrupt enabled) instruction before executing an interrupt program. To temporarily disable an interrupt, execute a DI (Interrupt disabled) instruction. When an interrupt is disabled, subsequent interrupts are not executed but stored until the next EI instruction.

"EI instruction", "DI instruction" (p. 3-193)

Example of an interrupt program

2008 EI HSP 0000

An interrupt program is not executed unless an EI instruction is executed. Set the input time constant shorter by using the HSP instruction (to 10 s) or by turning ON special utility relay 2813.

END INT 0000

Write the interrupt program between the END and ENDH instructions.
RETI ENDH

Note 1: To shorten the input time constant, use the HSP instruction (to 10 s) or specify the desired value in DM1940 and turn ON special utility relay 2813. Note 2: For more about the input time constant, refer to "1.4.1 Input Time Constant Change Function" (p. 3-23). Note 3: Use SET-RES instructions instead of OUT-OUTB instructions within interrupt programs. The following instructions cannot be used within interrupt programs: TMR, TMH, TMS, DIFU, DIFD, W-ON, W-OFF, W-UE, W-DE, STG, JMP, ENDS, HKEY, ITVL, @xxxx (differentiation type instructions), C, UDC, SFT

This section describes direct input and output.

3.3.1 Direct Input

The direct input function is used during interrupt processing. Direct input allows the KV PLC to fetch the input status of the input relays during execution of the interrupt program. Direct input is available only with input relays 0000 through 0015 (KV-10xx: 00000005, KV-16xx: 0000-0009). (KV-300: 0000-0005) The input time constant must be set to 10 s by using the HSP instruction or by turning ON special utility relay 2813. The direct input data is effective only within the interrupt program so that the internal utility relay must be provided.

Tips
Unlike software-based counters, the high-speed counter is a hardware-based, program-independent counter. It achieves an input response frequency of 30 kHz without being affected by the scan time. Input relays 0004 and 0005 can independently count the pulses with a 30 kHz input response frequency. Two-phase encoder input can be captured through two channels (30 kHz). CTH0 uses input from relay 0004 as phase A input and input from relay 0006 as phase B input (KV-10xx: 0000). CTH1 uses input from 0005 as phase A input and input from 0007 as phase B input (KV-10xx: 0001).

Note: When phase differential input is used, pulses with a maximum frequency of 30 kHz can be counted, provided the pulses have a duty ratio of 1:1 (50%) and phase difference of 90. Inputting pulses with an irregular duty ratio or phase difference will decrease the allowable input frequency.

4.2.1

High-speed Counters and High-speed Counter Comparators

The high-speed counter is a hardware-based counter that can count high-speed pulses that cannot be counted by counters written in main routines (C or UDC). (Pulses with a maximum frequency of 30 kHz can be counted.). * High-speed counter comparators are hardware-based comparators that compare their preset value with the current value of one of the a high-speed counters. Both counters and comparators perform processing with hardware rather than software programs, enabling high-speed performance independent of the scan time.

Note 1: As with the internal register, the contents of data memory are stored as 16bit binary data. Note 2: The contents of data memory are stored even when the Visual KV is turned off or "ALL DATA MEMORY CLEAR" is executed. It is stored more than 20 days with the KV-10xx, and more than two months with other models.

Specifications of high-speed counters

The high-speed counter is a hardware-based up/down counter that counts from 0 to 65535 with an auto-reset function. The following operands can be specified for count inputs.
High-speed counter CTH0 CTH1 Operand 2100 to 2102, 0004 2200 to 2202, 0005, 0500 Measurement range #00000 to 65535

High-speed counters CTH0 and CTH1 store current values only. When input relays 0004 and 0005 are selected as operands, they can be used as high-speed counters with a response frequency of 30 kHz. When special utility relays 2100 through 2102 and 2200 through 2202 are selected as operands, the high-speed counters can be used as high-speed timers. When relay 0500 is selected as an operand for CTH1, CTH1 can count the clock pulses produced by CTH0. CTH0 and CTH1 can be used as 24-bit high-speed counters when the MEMSW instruction is set.
"MEMSW instruction" (p. 3-92), "4.4.1 24-bit High-speed Counter" (p. 3-221), "4.3.4 Count Input Method" (p. 3-212), "When using comparator output from other counters as count input" (p. 3-213).

3-208

Chapter 4 High-speed Counters

4.2 Outline of High-speed Counters

Note 1: CTH instructions cannot be duplicated in a program. A maximum of two counters, CTH0 and CTH1, can be used in one program. Note 2: The operands for a high-speed counter cannot be changed during program execution. Note 3: When using a high-speed counter with external inputs, the input time constant must be set to 10 s with the HSP instruction or with special utility relay 2813. (Pulses with a maximum frequency of 30 kHz can be counted.) Note 4: When using input 0004 as an operand, use input 0006 (KV-10xx: 0000) for phase B input. Therefore, do not use input 0006 (KV-10xx: 0000) other than for the high-speed counter. Note 5: When selecting no multiplication mode, and you do not want to use input 0006 (KV-10xx: 0000) as phase B input, turn ON special utility relay 2407. Note 6: When using input 0005 as an operand, use input 0007 (KV-10xx: 0001) for phase B input. Therefore, do not use input 0007 (KV-10xx: 0000) other than for the high-speed counter. Note 7: When selecting no multiplication mode, and you do not want to use input 0007 (KV-10xx: 0001) as phase B input, turn ON special utility relay 2415. Note 8: When using the high-speed counter internal connection relay 0500, only single-phase input is available. In this case, external input relays 0005 and 0007 for CTH1 can be used as normal input relays. Note 9: When using phase differential input, pulses with a maximum frequency of 30 kHz can be counted, provided the pulses have a duty ratio of 1:1 (50%) and phase difference of 90. Inputting pulses with an irregular duty ratio or phase difference will decrease the allowable input frequency. Note 10: The current value of the high-speed counter is stored with a built-in, electrical double-layer capacitor for more than two months at 25C (KV-10xx: more than 20 days). The value can also be stored in EEPROM. "3.5 System Mode" (p.1-94).

High-speed counter comparators

The high-speed counter comparator (CTC) compares its preset value with the value of the high-speed counter (CTH). The CTC contact turns ON when the current value of the CTH matches the preset value of the CTC. Among CTC contacts, the ON/OFF status of output relays 0500 and 0501 can be changed with hardware (direct output) or can be used to execute an interrupt. Set special utility relays (2103 to 2112, 2203 to 2212) to change the ON/OFF status of output relays 0500 and 0501. The following table shows the relationship between the high-speed counters and high-speed counter comparators.
High-speed counter CTH0 CTH1 High-speed counter comparator CTC0, CTC1 CTC2, CTC3 Preset value range #1 to 65535 Direct output 0500 0501 Interrupts INT CTC0, INT CTC1 INT CTC2, INT CTC3

Note 1: Once the high-speed counter comparator turns ON, it remains ON until a RES instruction is encountered. Note 2: When a high-speed counter comparator is used as an interrupt, the interrupt is executed as soon as the current value of the high-speed counter reaches the preset value of the comparator. At the same time, the contact for the high-speed counter comparator automatically turns OFF. Note 3: CTC2 or CTC3 cannot be used as comparators for CTH0; CTC0 or CTC1 cannot be used as comparators for CTH1. Note 4: Do not specify "#00000" as the preset value for CTC0 through CTC3.

Resets the counter at the instant the external reset input relay turns ON. The external reset is assigned to input relay 0008 (KV-10xx: 0002) for CTH0, and input relay 0009 (KV-10xx: 0003) for CTH1. The timing of the reset can be changed by setting relays 2400 and 2401 (for CTH0) or 2408 and 2409 (for CTH1) as follows. This reset operation is independent of the scan time.

The current value of CTH can be changed to any desired value by using the external reset function of input relays 0008 (KV-10xx: 0002) (for CTH0) or 0009 (KV-10xx: 0003) (for CTH1) specified with special utility relays 2400 and 2401 (for CTH0) or 2408 and 2409 (for CTH1). (The external reset function sets the value to "0".) Write the desired value of the preset input into the following data memories:
DM No. DM1924 (low-order bits), DM1925 (high-order bits) DM1926 (low-order bits), DM1927 (high-order bits) Description Preset value for CTH0 Preset value for CTH1

Use the STA or DW instruction to write data to the data memory. Note 1: The preset function is available only with the external reset input. The CTH value is reset to "0" with other resetting methods. Note 2: Use the SET, RES instruction pair to set the special utility relays. Note 3: When 16-bit high-speed counter is used, write the preset values into DM1924 and DM1926 only.

4.3.6 Differences with the CTH Instruction between the Conventional and Visual KV Series

0001 CTH0 0004

Input-enable relay

Count input

With the conventional KV Series, the current value of the high-speed counter is reset when the CTH instruction is executed while the input-enable relay is OFF. However, the counter continues counting until the end of the scan time. As a result, when the input-enable relay starts counting again, the counter may already be incremented by the length of the scan time. With the Visual KV Series, the current value of the high-speed counter is reset at the falling edge of the input-enable relay, so that the counter does not continue counting.

High-speed counter (CTH) The conventional KV Series includes high-speed counter CTH0, which is an 8-bit counter. The period of the internal clock is different from that in the new KV Series. The Visual KV Series allows you to reset a high-speed counter with external inputs. Its high-speed counter CTH0 is a 16-bit counter (can also be used as 24bit counter). With the Visual KV Series, when using the high-speed counter, the input time constant must be set shorter by using the HSP instruction or by turning ON special utility relay 2813. Phase differential input The Visual KV Series allows phase differential input for the high-speed counter. Response frequency The Visual KV Series provides a response frequency of 30 kHz. High-speed counter comparator The high-speed counter comparator turns ON the contact when its preset value matches the current value of the high-speed counter. Consequently, the contact may turn ON during the scan time. Be careful when using the contact for one comparator in several points in a program. Special utility relay A portion of the special utility relay assignment is different from that of the conventional KV Series.

"Setting the 24-bit high-speed counter comparator" (below) and "4.4.2 Changing the Current Value of a 24-bit High-speed Counter" (p. 3-223)

Note 1: Use the SET, RES instruction pair to set the special utility relays. Note 2: The 16-bit/24-bit high-speed counter setting with the MEMSW instruction is effective when the Visual KV is in RUN mode. You must change the program to change between 16-bit and 24-bit settings.

Setting the 24-bit high-speed counter comparator

To specify the preset value for the 24-bit high-speed counter comparator, write the value into the write area DM1916 to DM1923 and execute the STA and CTC instructions to specify or change the preset value. When the setting or change is properly performed, the CTC read areas DM1904 through DM1911 are updated with the new values after one scan. Changing the preset value Change the preset value for the 24-bit high-speed counter comparator using the Access Window, programming support software, handheld programmer, or operator panel with the following procedure. 1. Write the desired preset value into data memory. Write the desired preset value to the CTC preset value write areas DM1916 through DM1923.

2. Change the preset value of CTC. (See the notes on the next page.) With the Access Window Call CTC in device mode and change the value. With the "KV IncrediWare (DOS)" programming support software Change the preset value of CTC with the "Edit Device CTC" [F2] option. With the "LADDER BUILDER for KV" programming support software Change the preset value of CTC in the dialog box. With the KV-P3E(01) handheld programmer Change the preset value of CTC with the "TIMER COUNTER SETTING CHANGE" function.
For more about detailed operation, refer to "Chapter 3 Access Window" (p. 1-79), "Chapter 6 Handheld Programmer" (p. 1-195) and "Chapter 2 Instructions" (p. 3-33).

Note 1: When the preset value of a 24-bit CTC is changed with an instruction such as STA CTC0, the value entered as an operand is ignored but the value written in DM1916 through DM1923 is referred to and used as the preset value. Note 2: Be sure to write the desired value to the write area of the high-speed counter comparator preset value (DM1916 through DM1923) before executing the change operation (e.g., STA instruction).

This section describes the specified frequency pulse output function, frequency counter function, and cam switch function.

4.5.1 Specified Frequency Pulse Output Function

With high-speed counter CTH1, output pulses from output relay 0501 with the frequency (Hz) specified in data memory DM1936. To activate this function, write the desired value into DM1936 and turn ON special utility relay 2306. The internal clock of the high-speed counter is automatically set to 1 s. Pulses with duty ratio of 1:1 are output at the preset frequency obtained with the calculation "1,000,000/2/Output frequency". The KV performs the following operations after each scan time during the specified frequency pulse output function. Stops pulse output when special utility relay 2306 is turned OFF. Sets the preset value so that pulses are output at the frequency specified with the DM. (Pulse duty ratio: fixed to 50%) Starts pulse output.

Pulse duty Pulse duty is the ratio of the pulse widths between ON time and OFF time. A pulse duty of 50% means that the pulse widths between ON time and OFF time are the same, as follows.
ON OFF

The ratio between ON and OFF time is 1:1.

Setting method Set the desired output frequency (Hz) into DM1936. The available range is 16 Hz to 50 kHz (16 to 50000). Pulses are output when special utility relay 2306 is ON. The output is stopped when the relay is turned OFF. If an unacceptable frequency is specified, special utility relay 2307 (error relay) turns ON. Special utility relay 2306 is turned OFF and pulse output is stopped. Note 1: The available minimum frequency specified in DM1936 is 16 Hz. Note 2: The output is stopped when a value of 15 or less is specified in DM1936. Note 3: Starts and stops of pulse output or frequency changes are executed after each scan. Note 4: It takes a maximum of 200 s from when the output command is issued until pulses are output. Note 5: CTH1 and special utility relays 2200 through 2215 cannot be used when the specified frequency pulse output function is used.

Operation flow 1. Set the high-speed counter with external input. Use the END instruction and measure how much time has elapsed since the last measurement in units of 10 s. After each scan, pulses are counted within the time specified with the data memory. The frequency is calculated from the count value and written into data memory. 2. When the time specified with DM1404 elapses from the last measurement, the current value of CTH0 is fetched and divided by the elapsed time (Unit: 10 s). The frequency is obtained with the following calculation. Frequency (Hz) = (100,000 x Pulse count)/Elapsed time (Unit: 10 s) 3. The calculation result (Hz) is written into DM1405. Setting method 1. Specify the counting period for the frequency counter (the interval of frequency measurement [Unit: ms]) in data memory DM1404. 2. The preset value must be greater than the scan time. When a value smaller than the scan time is specified, the frequency is measured each scan time. Note 1: To use the frequency counter function, set the input time constant to 10 s with the HSP instruction or the special utility relay. (A maximum frequency of 30 kHz can be measured.). Note 2: The counting start/stop or measurement result is updated after each scan. Therefore, the counting period includes some scan time errors for the time specified with DM1404. Set the counting period so that overflow does not occur at CTH. Note 3: Specify the counting period so that the number of pulse inputs in one period is between 2 and 65535, inclusive. Note 4: Measurement may fail when the pulse period is 5000 ms or more. Note 5: The frequency counter cannot be used when CTH0 is used in the ladder program. Note 6: Special utility relays concerning CTH0, CTC0/1, and the cam switch cannot be used. Note 7: CTH0 and the cam switch function cannot be used when the frequency counter is used.

Description: When start relay 2314 is turned ON, the Visual KV automatically turns OFF start relay 2314 and turns ON in-operation relay 2715 to activate the cam switch function. When in-operation relay 2715 is turned OFF, the cam switch function is stopped.

Cam switch mode

Simulates a cam operation. Connect an encoder to CTH0 to count pulses in double multiplication mode. CTH0 uses input relays 0004 (phase A), 0006 (phase B) (KV-10xx: 0000), and 0008 (phase Z) (KV-10xx: 0002). Relays are turned ON/OFF when the pulse count reaches the specified angle. The cam switch function controls a maximum of 32 successive relays. Specify relay Nos. with the data memory (DM1400). Each relay is turned ON/OFF once every rotation. To turn relays ON/OFF several times in one rotation, use the OR instruction in the ladder program. Devices used in cam switch mode Data memory

Even a single phase incoder can be used by changing a part of the cam switch function. To activate the multi-step comparator mode, write the value to be compared into data memory DM1401 to replace the CTH0 value. This value determines the resolution.

9. Turn OFF special utility relay 2715 to stop the operation. Note 1: When the cam switch function is used, 32 relays from the relay No. specified with DM1400 is occupied for the function regardless of whether they are used or not. As a result, these relays cannot be used for any other purpose. Note 2: To use the cam switch mode, set the input time constant to 10 s with the HSP instruction or the special utility relay. (A maximum frequency of 30 kHz can be measured.) Note 3: When any improper value is set in data memory, the setting error occurs and special utility relay 2315 turns ON. Note 4: CTH0 and the frequency counter function cannot be used while the cam switch function is being used. Note 5: The cam switch function cannot be used when CTH0 is used in the ladder program. Note 6: Special utility relays concerning CHT0, CTC0/1, and the frequency counter function cannot be used. Note 7: The scan time is extended by a maximum of 16 ms when the cam switch function is activated. Note 8: The in-operation relay of the cam switch function (2715) remains ON even when the mode is changed or the power is turned OFF. Note 9: Use the END instruction to change relays or turn them ON/OFF. Note 10: When the encoder is ON in cam switch mode while the KV is OFF, the count may be shifted for the time between the start-up and phase Z input. Note 11: The encoder count is stopped in cam switch mode while the Visual KV is OFF. (While the Visual KV is ON, the count is continued even in PROGRAM mode.) Note 12: When a value of 360 or more is specified as the preset angle for the cam switch function, the value is converted into one within the range of 0 to 360 before the control. Example: When 500 is specified, it is converted to 140.

4.6.1 Outline of Direct Clock Pulse Output

Visual KV Series Only

This section describes the outline and setting method for direct clock pulse output.

Using the high-speed counter (CTH) and high-speed counter comparator (CTC), the KV PLC can output clock pulses directly through output relays 0500 and/or 0501 without any delays caused by the scan time. The period (frequency) and width of the pulses are determined by the period of the internal clock used for the high-speed counter (CTH) and high-speed counter comparator (CTC). The period of the clock pulse (frequency) can be changed with the program within the following ranges.
Output Internal clock 2100 (1.0 s) 0500 2101 (10.0 s) 2102 (100.0 s) 2200 (1.0 s) 0501 2201 (10.0 s) 2202 (100.0 s) Range of pulse period (Frequency) 20 s (50 kHz) to 65.5 ms (15 Hz) 20 s (50 kHz) to 655.3 ms (1.5 Hz) 200 s (5 kHz) to 6553.5 ms (0.15 Hz) 20 s (50 kHz) to 65.5 ms (15 Hz) 20 s (50 kHz) to 655.3 ms (1.5 Hz) 200 s (5 kHz) to 6553.5 ms (0.15 Hz)

Pulses of the internal clock are counted with the high-speed counter (CTH). When the number of current pulses reaches the preset value of the high-speed counter comparator (CTC), the ON/OFF status of output relays 0500 and/or 0501 is toggled to output direct clock pulses. Count value

Note 1: The operation of output relays 0500 and 0501 are determined by setting the special utility relays. Note 2: For more about setting special utility relays, refer to "4.2 Outline of Highspeed Counters" on page 3-206. Note 3: The ON/OFF status when the direct clock pulse output is started is the same as when the last direct clock pulse output is stopped. (Initial status: OFF) Note 4: Output relays 0500 and 0501 cannot be used in a normal program during direct clock pulse output.

4.6.2 Pulse Output Setting with the High-speed Counter Comparator

Changing the pulse period and width

Visual KV Series

By using two high-speed counter comparators, you can change only the pulse width while keeping the pulse period constant, or change only the pulse period while keeping the pulse width constant. The following examples illustrate how the pulse width and period can be selected with the high-speed counter comparator. ON-OFF ratio of 1:1
ON/OFF status is set by special utility relays.

Pulse width

Pulse period

Pulse width (s) = CTC0 preset value x internal clock (s) Pulse period (s) = CTC0 preset value x 2 x internal clock (s) Use the following calculation to obtain the pulse period from the frequency: Pulse period (s) = 1,000,000/Frequency (Hz)

Example:

To output 10-kHz pulses Pulse period = 1,000,000 10,000 = 100 s Preset value for CTC0 = 10 2 1 = 50

Variable pulse width The period and width of the pulse can be changed by changing the preset values of CTC0 and CTC1.
ON/OFF status is set by special utility relays.

Pulse width

Pulse period

Pulse width (s) = CTC1 preset value x internal clock (s) Pulse period (s) = CTC0 preset value x internal clock (s) Change CTC1 preset value to change the pulse width. Change CTC0 preset value to change the pulse period.

Note: The pulse width determined above is the pulse width produced inside the Visual KV PLC. In reality, the output pulse width may vary depending on the response delay of the output circuit and the load connected to this circuit. Be sure to determine the pulse width after monitoring the actual output waveform with an oscilloscope. (Monitor the pulses of variable pulse width.)

Note 1: Set the CTC preset value to 10 or more when the operands for the highspeed counter (CTH) is 2100 and 2200. The clock pulse output may be improper when the preset value is set to less than 10. Note 2: The pulse width may vary depending on the load connected to the circuit. Be sure to determine the pulse width after monitoring actual output waveform with an oscilloscope. Note 3: When CTC0 and CTC1, or CTC2 and CTC3, are used to output the clock pulse, do not specify the same value for the preset values of CTC0 and CTC1, or of CTC2 and CTC3.

Special utility relay setting Set the special utility relay (2103 through 2112) according to the following table.

Obtain the preset value of CTC0 by substituting 1 ms for the pulse period and 10 s for the internal clock (special utility relay 2101). In this case, the preset value of CTC0 is "50". Refer to the following table for the preset value of CTC0 with other internal clocks.

Sets the pulse output from output relay 0500 with special utility relays 2104 through 2107. In this example, turns OFF 2104 to enable direct output from 0500 and turns ON 2107 to reverse the output each time the CTH0 value reaches the CTC0 value.

Visual KV Series

5.1.1 Ramp-up/down Control

The Visual KV Series can directly output clock pulses not affected by the scan time to output relay 0502. If the frequency, the number of output pulses, and the acceleration time of the clock pulses have been preliminarily set to data memories, the Visual KV Series automatically performs ramp-up/down control. The ramp-up/down control output function offers ramp-up/down timing charts of the startup frequency, operating frequency, acceleration time, and deceleration time as shown below. The output frequency can be set within the range of 200 to 50,000 Hz.

5.2 Parameter Setting and Operating Procedures

Visual KV Series
This section describes the parameter setting and operating procedures for positioning control.

5.2.1 Parameter Setting Procedure

Preliminarily set each parameter for positioning control to a corresponding data memory. To operate, special utility relays must be set.

For more about special utility relays, refer to "5.2.2 Operating Procedure" (p. 3-257).

The table below shows the relationship between parameters and data memories. Data memories for ramp-up/down control

Note: When pulse output is started, the scan time is extended by 10 ms maximum (if the acceleration/deceleration time is set to 4 s).

Set value error code (DM1486)

If there is an error in the preset parameters when starting operation, a corresponding error code (11 to 17) is automatically written to DM1486.
Code 11 12 13 14 Description Startup frequency value is smaller than allowable setting range. Operating frequency value is smaller than allowable setting range. Operating (or startup) frequency value is larger than allowable setting range. Startup frequency value is larger than operating frequency value. Acceleration/deceleration time is larger than allowable setting range. System error Number of pulses output within acceleration/deceleration time is too small. Countermeasures Set starting frequency within setting range (200 to 50,000). Set operating frequency within setting range (200 to 50,000). Set operating (or startup) frequency within setting range (200 to 50,000). Set them appropriately so that startup frequency is smaller than operating frequency. Set acceleration/deceleration time within setting range (0 to 4,000). Contact our sales office. Set number of output pulses to 2 or more.

15 16 17

Startup frequency (Hz) (DM1480)

Set the frequency (speed) of the motor at startup in positioning control so that motor rotations start up smoothly. At the set frequency, the Visual KV Series will output clock pulses.

Chapter 5 Positioning Control

5.2 Parameter Setting and Operating Procedures

Operating frequency (Hz) (DM1481)

Set the frequency (speed) of the motor during operation in positioning control. At the set frequency, the Visual KV Series will output clock pulses.

Visual KV Series

Note: If the startup frequency is the same as the operating frequency, the timing chart becomes as shown below.
Operating (startup) frequency
0

In this case, the acceleration/deceleration time is ignored.

Acceleration/deceleration time (ms) (DM1482)

Set the time to accelerate from the starting frequency to the operating frequency after operation is started. When operation is stopped, the deceleration time is equivalent to the acceleration time. In the set time, the Visual KV Series varies the clock pulse frequency from the startup frequency to the operating frequency (in the case of acceleration time). The clock pulse frequency change cycle within the acceleration time is fixed to 5 ms.
Operating frequency

Startup frequency

5ms Acceleration/deceleration time

Number of output pulses (DM1484 and DM1485)

Set the angle of rotation (movement quantity) in positioning control as the number of pulses. The Visual KV Series outputs as many clock pulses as the set value. If the number of output pulses is larger than 65,535, divide it into the upper 16-bit value and the lower 16-bit value using the following equation. The minimum value is 2, and maximum value is 4,294,967,295. (Number of output pulses) 65,536 = A (answer) . . . B (remainder) A = Number of output pulses (upper 16-bit) DM1485 B = Number of output pulses (upper 16-bit) DM1484 Note 1: When the set number of pulses is too small and the target value cannot be achieved, triangular control is performed as shown below.

5.2.2 Operating Procedure

In positioning control, operation is started up, stopped normally, and stopped in emergencies by the ON/OFF status of special utility relays. The table below shows the relationship between operations and the special utility relays used.
Special utility relay No. 2308 2309 2310 R/W* Function W R W W Stop Run RESET Start Description Performs deceleration at rising edge, then stops operation. Remains ON while pulses are output. Stops operation immediately when being reset in an interrupt program. Starts up operation at rising edge.

2310 (START) 2309 (RUN) 2308 (STOP)

When relay 2310 turns ON, clock pulses are output (detection at rising edge). While clock pulses are output, relay 2309 remains ON. While clock pulses are not output, relay 2309 remains OFF. When relay 2308 turns ON, clock pulses are decelerated and stopped (detection at rising edge).

Note 1: If there is no error in the parameter setting when special utility relay 2310 turns ON at startup of the clock pulses, special utility relay 2309 turns ON and clock pulses are output. Note 2: If there is an error in the parameter setting, special utility relay 2309 does not turn ON but a corresponding error code is written to DM1486. Confirm the error code, and change the erroneously set parameter. Note 3: By setting special utility relay 2309 to OFF in an interrupt program, clock pulses can be immediately stopped. Note 4: Rising of special utility relay 2310, falling of special utility relay 2309, and rising of special utility relay 2308 are performed by end processing and RETI. (Special utility relay 2309 turns ON at that time.) Note 5: It takes a maximum of 10 ms from when special utility relay 2310 turns ON until pulses are output. Note 6: Even if special utility relay 2310 is set to ON while special utility relay 2308 or 2309 is ON, it is ignored. Note 7: When pulse output has finished, special utility relay 2309 is immediately set to OFF (without regard to the scan time).

Ladder example of automatic operation (palletizing operation)

A palletizing operation is automatically performed. The machine moves to a target coordinate, then returns to the start position. Next, the machine moves to a position further away than the target coordinate, then again returns to the start position. Such an operation is realized using repetitious and return movements. This type of operation is suitable for, for example, a job where workpieces to be supplied are located in one position and a moving body picks up the workpieces and positions them little by little at a certain interval.

When start signal 0000 is set to ON, a moving body moves to point 1, returns to the start position, moves to point 2, and then returns to the start position again. Afterwards, the moving body moves to point 3, then returns to the start position, output 05000 remains ON for 3 seconds, and then the operation is finished. Program example

Routine program flow is shown by the thick arrow on the left of Fig.1. In this case, input signals can be received only during input processing. Although input time constant can be made shorter by using HSP or by turning ON special utility relay 2813, input signals can be received only if they are longer than the duration of one scan time. When an interrupt initiation input turns ON, the currently running program is suspended to immediately execute the interrupt routine. During execution of interrupt routine, input signals shorter than one scan time can be received by the PLC. Note: To execute INT (interrupt initiation instruction), execute EI first to enable interrupt, then use HSP (time constant: 25 s) or turn ON special utility relay 2813 (time constant: 10 s) to reduce the input time constant.

6.1 Interrupt Instructions

Interrupt priority
If two or more interrupts are generated at different timings, interrupt routines are executed in the order that interrupts are generated. If two or more interrupts are generated simultaneously, interrupt routines are executed according to the priority shown below. CTC0 > CTC1 > CTC2 > CTC3 > 0000 > 0001 > 0002 > 0003 * Note that the above priority differs from that for other KV PLCs (KV-10/16/24/40/ 80). The priority is: 0000 > 0001 > 0002 > 0003 > CTC2 > CTC3 > CTC0 > CTC1.

Note 1: During execution of one interrupt routine, execution of other interrupt routines is inhibited. (One interrupt routine can be executed inside another interrupt routine by inserting EI.) Note 2: If other interrupts are generated during execution of one interrupt routine, the routines of these interrupts are executed after completion of the first interrupt routine in the order that they are generated. Note that generation of up to 8 levels of interrupt nesting or up to 8 individual interrupts can be stored during execution of interrupt routine. However, generation of an interrupt is ignored if generation of the same interrupt has already been stored.

Description
When 1000 is ON, execution of interrupt is enabled. When 1000 is OFF, execution of interrupt is disabled. Interrupts are enabled between EI instruction and DI instruction. Therefore, once EI is executed, interrupt is enabled until it is disabled by DI. With the KV, any interrupt is disabled when the operation is started. DI instruction disables execution of interrupt. Use this instruction to temporarily disable interrupt. EI instruction enables the execution of interrupt. Use this instruction to release interrupt disabled by DI instruction. During execution of an interrupt, any other interrupt is disabled.To execute another interrupt during execution of the previous interrupt, include EI instruction in this first interrupt. Interrupts can be nested up to 8 levels by executing EI in each interrupt routine. Note 1: Generation of up to 8 levels of interrupt nesting or up to 8 individual interrupts can be stored while interrupt is disabled. These interrupts are executed after EI has been executed. Note 2: Generation of INT CTC is erased from the storage when RES CTC is executed.

6.1 Interrupt Instructions

Initial setting When the operation is started, EI instruction enables interrupts. Special utility relays No. 2200 through 2215 are turned OFF. Turning OFF 2203 disables CTC2 from resetting the CTH1 current value to 0. Turning OFF 2206 allows interrupt to be generated at the rising edge of INT0003. The value of DM0000 is reset to "0". Turning ON special utility relay 2813 changes the input time constant to 10 s. 1.0-s internal clock pulses are counted using CTH1. INT instruction with 0003 as the operand allows interrupts to be executed. When interrupt is generated for the first time, 2206 is OFF. Therefore, program in rung (a) is executed. Then, KEEP turns 2206 ON. When interrupt is generated for the second time, 2206 is ON. Therefore, program in rung (b) is executed to calculate the following: (TM30 at 2nd execution) - (TM30 at 1st execution) = pulse width (unit: 1.0 s) The result is stored in DM0000.

Initial setting When the operation is started, EI instruction enables interrupts. Turning ON special utility relay 2203 allows CTC2 to reset the CTH1 current value to 0. The CTH1 current value is reset to 0. The CTC2 preset value is set to 5000. Turning ON special utility relay 2813 changes the input time constant to 10 s. Pulses input to 0005 are counted using CTH1.

INT CTC2 is used to execute the interrupt. (Interrupt routine is executed when the CTH1 current value and CTC2 preset value are equal.) Immediate output to 0501 is performed.

Note 1: When the interrupt is executed, the contact of CTC2 is automatically reset. Note 2: The operand used for INT instruction is not allowed for use with other INT instructions.

6.2 High-speed Counters

High-speed counter and counter comparators High-speed counter (CTH1) CTH1 is a 16-bit hardware counter that counts from 0 to 65535. You can specify the operands listed in the table below as the count input. You can specify one operand from the table below. Operand cannot be modified externally during execution of the program. When the external pulse (0004, 0005) is selected, CTH1 is used as a High-speed counter with a response frequency of 30 kHz.* When one of the internal clocks (2100 to 2102, 2200 to 2202) is selected, CTH1 is used as a High-speed timer. When the external pulse 0500 is selected as input to CTH1, CTH1 can count direct clock pulses generated by CTH0.

At the contact of High-speed counter comparator (CTC), the level of output (0500, 0501) can be changed (directly output) through hardware or an interrupt can be generated. To change the level of output 0500 and 0501, set the desired value (ON/ OFF) to special utility relays 2103 to 2112, 2203 to 2205, and 2207 to 2212.

6.2 High-speed Counters You cannot change operands of the high-speed counters (CTH) during execution of the program. The input time constant of the high-speed counters is usually set to 25 ms. (The HSP instruction is not required.) High-speed pulses can be counted at up to 30 kHz through external inputs (0004 to 0007) by turning ON special utility relay 2813. (Internal pulses can be counted at up to 50 kHz by turning ON 2813.)*

Outline of Pulse Output

The KV PLC can output clock pulses through 0500 and/or 0501 without any delays caused by scan time. (Through CPU only) Direct clock pulses, used with the high-speed counters, are applicable for various types of production control such as for controlling target positions at desired speed. To perform ramp-up/down control, see "Controlling stepping motors" in Chapter 5. A setting of the clock pulse cycle (frequency) can be changed by the program within the allowable range as shown in the table below.

Pulse period and width

Period and width of the pulse is determined by the period of the internal clock (CTH) used and the preset value of the comparator (CTC). When two counter comparators are used, only the pulse width can be changed while a constant period is maintained. The following examples illustrate how pulse width and period can be selected: ON/OFF ratio of 1:1 Pulse width (ms) = CTC0 preset value x internal clock (ms) Pulse period (ms) = CTC0 preset value x 2 x internal clock (ms)

Calculating the pulse cycle and comparator setting value

The KV-300 CPU supports clock pulse output at maximum frequency of 50 kHz. Obtain the pulse cycle for clock pulse output and comparator setting value from the following expressions: Pulse cycle Pulse cycle (s) = 1000 Frequency (kHz) For pulse with 1:1 ON/OFF ratio (using one comparator) CTC setting value = Pulse cycle (s) Internal clock (s) 2
ON OFF

For pulse with variable pulse width (using two comparators) CTC setting value for pulse width = Pulse width (s) Internal clock (s) CTC setting value for pulse cycle = Pulse cycle (s) Internal clock (s)

CAUTION

When setting 2100 or 2200 for the operand of High-speed counter CTH, set 10 or greater value to CTC. Otherwise, clock pulse is not correctly output. The pulse width varies depending on the influence of the connected load. Before setting the pulse width, you should measure the actual waveform using an oscilloscope. When generating clock pulse using CTC0 and CTC1, or CTC2 and CTC3, do not set the same value to CTC0 and CTC1, or CTC2 and CTC3. If setting the same value, clock pulse is output at the double clock cycle.

Although smoother trapezoidal control can be obtained by setting a smaller acceleration rate, the acceleration time is extended. Be sure to turn OFF input relay 0007 (phase B input).

Operation This program sets the parameters as below: DM0000 = 8000 [Hz], DM0001 = 700 [Hz], DM0002 = 400 [Hz/10 ms], DM0003 = 4000 pulses The program performs trapezoidal control as shown above when start switch 0000 is pressed, and stops control when pulse count reaches 4000. The program restarts operation by re-pressing the start switch. It performs reverse operation while reverse switch 0001 is ON.

6.3 Positioning Control

6.3.1 Positioning Control (Ramp-up/down Control)
Outline of positioning control
The KV-300 CPU outputs clock pulses, independent of scan time, directly through output relay 0500 or 0501. When the clock pulse frequency, output pulse count, and acceleration/deceleration time are set to the data memory addresses in advance, the KV-300 CPU automatically performs ramp-up/down control. Output frequency can be set within the range of 153 Hz to 50000 Hz.

Setting and application of parameters

This section describes how to set and apply parameters for positioning control.

Setting parameters
Set the parameters to the assigned data memory addresses. To operate the positioning control function, the special utility relays must be set. Refer to page 3-299. The following table shows the parameters and assigned DM Nos.
DMNo. DM9407 X-axis (0500) DM9408 DM9409 DM9410 DM9411 DM9412 Y-axis (0501) DM9413 DM9414 DM9415 DM9416 DM9417 Parameter Set value error code 0500 Start frequency (Hz) 0500 Run frequency (Hz) 0500 Acceleration/deceleration time (ms) 0500 Output pulse count (high-order 16 bits) 0500 Output pulse count (low-order 16 bits) 0501 Start frequency (Hz) 0501 Run frequency (Hz) 0501 Acceleration/deceleration time (ms) 0501 Output pulse count (high-order 16 bits) 0501 Output pulse count (low-order 16 bits) Allowable setting range Code 11 to 17 or FFFF (-1) is entered when error occurs 153 to 50000 153 to 50000 0 to 4096 0 to 65535 0 to 65535 153 to 50000 153 to 50000 0 to 4096 0 to 65535 0 to 65535

Note: Refer to the following expression to determine the output pulse count. Output pulse count < (65535 x pulse change cycle [ms]) (1000 x run frequency [Hz]) Pulse change cycle (t) The pulse change cycle is the cycle in which the output clock pulse frequency is changed for acceleration or deceleration. The pulse change cycle is obtained from one of the following expressions, whichever produces the smaller solution. However, when the start pulse is less than 500 Hz, the pulse change cycle becomes 14 ms or more. Pulse change cycle (t) [ms] = (acceleration time [ms] + 199) 200 x 4 or Pulse change cycle (t) [ms] = 1000 (run frequency [Hz] 1000)

Corrective action for error code 16 Error code 16 is issued when the output pulse count during acceleration/deceleration time exceeds other values calculated from the preset parameters. To recover from the error, the following corrective actions are available. Change the run frequency and/ or the acceleration/ deceleration time according to the following expression. 65535 Run frequency x Pulse change cycle x 65535 1000

Corrective action for error code FFFF (-1) Reduce run frequency and start frequency. Reduce accelleration/ deccelleration time.

Start frequency (Hz) Sets a start frequency (speed) to start the motor rotation smoothly during positioning control. The KV-300 CPU outputs clock pulses at the specified frequency. Run frequency (Hz) Sets the motor frequency (speed) during positioning control. The KV-300 CPU outputs clock pulses at the specified frequency. Note: When the start frequency equals the run frequency, the system operates as shown in the following chart.
Preset frequency 0

Here, the acceleration/deceleration time is ignored. The output count should be less than 65535.

Chapter 6 Interrupts, High-speed Counters, Positioning Control

6.3 Positioning Control

Acceleration/deceleration time (ms) Sets the time required when the start frequency accelerates to the run frequency at startup. In the same manner, sets the deceleration time required at stop. The KV300 CPU controls the clock pulse frequency from the start frequency to the run frequency within the specified time. The pulse change cycle within the acceleration time is obtained from one of the following expressions, whichever produces the smaller solution. However, the pulse change cycle when the start pulse is less than 500 Hz becomes 14 ms or more. Pulse change cycle (t) ms = (acceleration time ms + 199) 200 x 4 or Pulse change cycle (t) ms = 1000 (run frequency Hz 1000) Output pulse count Sets the positioning control rotation angle (moving distance) with the pulse count. The KV-300 CPU outputs as many clock pulses as specified. If the output pulse count is greater than 65535, set the pulse count separately for high-order 16 bits and low-order 16 bits based on the following expressions. (Output pulse count) 65536 = A (solution) B (remainder) A = Output pulse count (high-order 16 bits) B = Output pulse count (low-order 16 bits) Note: When the specified output pulse count is insufficient and does not reach the target value, the KV-300 CPU performs triangular control.
Run frequency Start frequency 0

The current pulse output value cannot be checked.

Note 1: When special utility relay 2310 (2313) is turned ON at start of clock pulse, 2309 (2312) turns ON and the clock pulse is output, assuming parameter settings are correct. Note 2: If a parameter setting for the X-axis or Y-axis is incorrect, 2309 (2312) does not turn ON and an error code is written into DM9407. Check the error code and adjust the parameter setting. Note 3: By resetting 2309 (2312) within the interrupt program, you can stop the clock pulse immediately. You must reset 2309 within the interrupt program; otherwise, the clock pulse is not stopped. Note 4: Because the clock pulse is output under software control, the pulse width is extended by 10 s to 20 s in the pulse change cycle. Test the clock pulse output on the KV-300 system before using it in practical applications.

7.2 Serial Communication

When the KV is connected to a personal computer, the current value or preset value of timers/counters or contents of data memories in the KV can be loaded to and modified on the computer.

7.2.1 Command Transmission Procedure

Commands are transmitted from a personal computer to the KV base unit as follows:
Transmits a break signal

Initialize the communication buffer and baud rate setting of the KV.

Transmits communications start command (CR)

Transmits a command

Receiving a response

Transmits communications end command (CQ)

Transmitting a break signal A break signal is used to initialize the communication buffer and baud rate setting of the KV. It is necessary to transmit a break signal of 100 ms or longer to the KV before starting communication. Another break signal is unnecessary once the communication is established. A break signal must have the waveform shown below.
+V SD -V
10 ms or longer 100 ms or longer

Note 1: For the first serial communication with a personal computer after the KVP3E(01) handheld programmer is connected to the KV, or after the "KV IncrediWare (DOS)" or "LADDER BUILDER for KV" programming support software is evoked, be sure to transmit a break signal. A break signal is unnecessary at other times. Note 2: If you cannot transmit a break signal, turn OFF the KV once to initialize the communication program. After that, restart communication between the KV and the personal computer. Note 3: Be sure to stop the communication for 10 ms or longer after transmitting a break signal.

Start communications with the KV.

Transmit a command which instructs the KV to perform the required operation.

Receive and check the response to the transmitted command.

End communications with the KV.

Chapter 7 Serial Communication

7.2 Serial Communication

Command/response format "Command" and "response" in communications between the KV and a personal computer are defined as follows: Command: Message transmitted from personal computer to KV Response: Answer to the command (message from KV to personal computer) When a personal computer transmits a command to the KV Series basic unit, the KV sends back a response to the personal computer. When creating a program to control the KV using a personal computer, create it so that the response is checked before the next command is transmitted.

7.2.2 Format of Commands/Responses

The formats of commands and responses are as follows: Command format Use the following format to transmit commands from the personal computer to the KV. [CR] is a delimiter. The KV ignores [LF] and recognizes the next character after [LF] as the next command.
Command Or Command C C R R L F

Response format The KV sends back a response to the received command in the following format. When creating a program using a personal computer, create it so that the personal computer can process the response in this format.
Response C R L F

Note 1: Be sure to transmit a break signal for the first serial communication with a personal computer after the KV-P3E(01) handheld programmer is connected to the KV, or after the "KV IncrediWare (DOS)" or "LADDER BUILDER for KV" programming support software is evoked. A break signal initializes the communication setting for the KV. If you cannot transmit a break signal, turn the KV OFF once to initialize the communication setting. The KV will not receive text data unless its communication setting has been initialized. Note 2: If [ETX] exists at some point in the text data, the KV writes the data before [ETX] into the data memory. The data after [ETX] is not written. Note 3: If KV receives text data while special utility relay 2804 (2809)*1 is ON, the received data is not written into the data memory. In this case, special utility relay 2802 (2807)*2 turns ON for one scan. Note 4: When parity errors or other errors occur during text data reception, the received data is not written into the data memory. In this case, special utility relays 2802 (2807) and 2803 (2808)*3 turn ON for one scan. Note 5: The KV-10xx includes only communication port A.

7.3 Loading Text Data

Special utility relay operation Two special utility relays are assigned for each channel for data transmission. Text data or a break signal is transmitted when the respective relay is turned ON/OFF.
Relay No. (Port A) 2804 2800 Relay No. (Port B) 2809 2805 Relay No. (KV-300/10/80) 2807 2803 Description Starts/stops transmitting text data. ON: Start, OFF: Stop Starts/stops transmitting break signal. ON: Start, OFF: Stop

Note 1: Be sure to transmit a break signal for the first serial communication with a personal computer after the KV-P3E(01) handheld programmer is connected to the KV, or after the "KV IncrediWare (DOS)" or "LADDER BUILDER for KV" programming support software is evoked. A break signal initializes the communication setting for the KV. If you cannot transmit a break signal, turn the KV OFF once to initialize the communication setting. The KV will not transmit/receive text data unless its communication setting has been initialized. Note 2: Turn ON special utility relay 2804 (2809) (SET 2804 [2809])*1 to transmit text data. Special utility relay 2804 (2809)*1 remains ON during text data transmission, and automatically turns OFF when the transmission completes. To forcefully stop the text data transmission, turn OFF special utility relay 2804 (2809) (RES 2804 [2809])*1. Note 3: A break signal is transmitted while special utility relay 2808*2 is turned ON. Use the SET-RES instruction pair or OUT-OUB instruction pair to control a break signal. The communication program of the destination KV is initialized after a break signal has been transmitted.
*1: 2807 with KV-300/10/80 *2: 2803 with KV-300/10/80

CAUTION

The double coil operates normally through different STG instructions. If different STG instructions turn ON simultaneously, the latter programmed instruction has the priority.
Conditional branching When input relay 0000 (start SW) turns ON, output relay 0500 turns ON. Then, as programmed for conditional branching, output 0501 turns ON for 1 s when 0001 turns ON or 0502 turns ON for 2 s when 0002 turns ON. After either one of the processes is completed, the program returns to the conditional branching and repeats the same steps. Ladder diagram
