You could sustain an electric shock.
S Turn the backlight off before replacing it. Otherwise you could sustain an elec-
tric shock.
Caution:
S Be sure to switch the power OFF before replacement.
S Do not use the PT touch switch input functions for applications where danger to
human life or serious property damage is possible, or for emergency switch ap-
plications.
S Before inserting or removing the connectors, make sure that the NT620S/
NT620C and the PC are turned OFF.
S During work at the panel, take care to ensure that no metal scraps enter the
unit. Otherwise, the product may malfunction.
S After connecting the communication cable, be sure to lock the connectors with
the screws. Otherwise the cable may disconnect, causing operation to fail.
S The cable’s tensile load is 30 N. Do not subject it to loads greater than this.
Otherwise a discontinuity may occur, causing operation to fail.
xiii
Safety Precautions 3
S When installing the PT in the operation panel, observe the following points.
– Do not install the unit at location where the ambient temperature goes out-
side the range 0 to 45_C in the case of the NT620S and 0 to 40_C in the case
of the NT620C, or where the relative humidity goes outside the range 35 to
85% RH.
If the ambient temperature exceeds the range indicated above, install a fan
or an air conditioner.
– Do not install the unit directly above equipment that generates a lot of heat
(heaters, transformers, large capacity resistors, etc.)
S Do not install the unit in locations where it will be subject to strong vibration or
severe shock.
S To ensure that the unit can be operated and maintained without difficulty, install
it at a distance from high-voltage equipment and power equipment.
S After changing the switch settings, always press the reset switch or turn the
power off and back on.
Otherwise the system will not operate as exported.
S Check that the current capacity of the equipment to be supplied is within 150
mA before using the +5 V output of pin No.6. The +5 V output of NT620S/
NT620C delivers +5 V "5% and 150 mA maximum.
Do not use the +5 V output of the RS-232C interface unit.
S Press touch switches with a force of no greater than 20 N. Applying higher force
may cause glass to break, cause injuries, and prevent operation.
S If touch switches are pressed in rapid succession, their inputs may not be suc-
cessfully received.
xiv
Safety Precautions 3
Confirm that the input of a touch switch has been successfully received before
moving on to the next operation.
S Do not press touch switches carelessly while the backlight is off or while noth-
ing is displayed on the screen. Otherwise the system may operate unpredict-
ably.
Only press touch switches after confirming system safety.
S When the numeral values entered are confirmed, upper/lower limits are
checked. Otherwise the system may operate unpredictably.
S Never short the battery terminals, attempt to charge the battery or take it apart,
heat it, or discard it into fire. In the worst case, explosion may occur.
S Never short the “+” and “–” terminals of the battery. Do not recharge, take apart,
or heat the battery, or discard it into open flame. Attempting any of these will
lead to hazards such as fire, leakage of electrolyte, rupture, etc.
When replacing a battery, ensure that the battery terminal does not touch the
board in the NT620S/NT620C.

Communication Using the Direct Connection Function Section 1-4
The NT620S/620C can be used to refer to the contents necessary for the display
information or to allocate the bits and words used for storing the input data to any
area in the PC. The NT620S/620C can directly write and read such allocated bits
and words so as to change the display elements, control the operating status,
and notify the status.
This function is called the “direct connection function”. The NT620S/620C is de-
signed exclusively for use with the direct connection.
The bits and words allocated by the direct connection function are called “allo-
cated bit” and “allocated word” respectively.
NT620S/620C PC
DM area Internal relay area
S The bits and words referring to operating status and work instruction informa-
tion and those for storing input data can be freely allocated to almost any part of
the PC memory. Bits and words in the PC can be referenced from any memory
table.
S The NT620S/620C can directly refer to PC bit and word data so that it can be
connected to a PC without changing the PC program which controls currently
running production line.
S The area used for control and notification of NT620S/620C statuses, including
displayed screens, whether the screen display is on or off, buzzer output, etc.,
can be freely allocated to any part of the PC memory.
The direct connection function allows the NT620S/620C to directly read and
write almost all bits and words in the PC and to automatically change the
NT620S/620C screen display. This function can reduce the load on the PC so
that the program development efficiency of the PC improves.
11
Communication Using the Direct Connection Function Section 1-4
1-4-2 NT Link
The NT link is a new communication method applied between the NT620S/620C
and a PC.
The PCs that can be connected using the NT link are as follows.
S When using the built-in host link of the CPU unit
CPM1 (RS-232C adapter required), CQM1, C200HS, C200HX/HG/HE,
CVM1/CV series PCs.
S When using a communication board
C200HX/HG/HE
When using the NT620S/NT620C in an NT link, two communications modes are
possible: a single NT620S/NT620C can be connected to one PC (1:1 NT link), or
alternatively, up to eight NT620S/NT620C units can be connected to a single PC
port (1:N NT link).
However, the 1:N connection NT link can be used with C200HX/HG/HE only. In
the following sections, the NT link communication mode in general will be indi-
cated by the term “NT link”, a 1:1 connection NT link will be indicated by “NT link
(1:1)”, and a 1:N connection NT link will be indicated by “NT link (1:N)”.
Features of the NT Link
S High speed communications with specific types of PCs can be executed.
S Writing in units of bits to the PC memory area is possible. (*)
This enables another bit of a word data to which a touch switch has been allo-
cated to be used for other purpose (e.g., to allocate a lamp).
S This can be used even when the PC is in the RUN mode.
When using the host link, the operation mode changes to the monitor mode.
S Provided the PT used is one that supports the NT link (1:N) (i.e., NT30/NT30C/
NT20S/NT600S/NT620S/NT620C), up to eight PTs can be connected to a
single PC port.
S When using C200HX/HG/HE, by installing an expansion communication
board in the option slot of the CPU unit, it is possible to connect up to three NT
link (1:N) systems (comprising a total of 24 NT620S/NT620C units). For de-
tails on communication boards, refer to the “SYSMAC C200HW-COM01 to
06-E Communication Board OPERATION MANUAL” (W304-E1-j).
(*) Except a DM area.
The NT link function is compatible with the host link function with respect to
screen data. The NT620S/620C screen data and the PC programs handled by
the host link direct connection can be used with for the NT link as they are.

Functions of the PT Status Control Area (PC to NT620S/620C)
The “PT status control area” is used to control the NT620S/620C status. When
data is written to this area in the PC, the NT620S/620C reads the contents and
operates according to the contents.

Seen from the perspective of the NT620S/NT620C, when using the memory link
method it makes no difference whether the “object” communicated with in direct
connection is external or internal, and therefore screen data for direct commu-
nication can be used without alteration by merely changing the object of commu-
nication.

Setting the Conditions of Communications with the PC by Using the Memory Switches Section 3-5
Memory Switches The NT620S/620C has the memory areas used to store the PC connection meth-
od, communications conditions, system settings, etc. which can be used as the
switches and called the “memory switches”. Since the memory switches use the
flash memory, the stored data can be held even when the power supply is turned
OFF.
Reference If the memory switch data is not backed up by the built-in battery, it will all be
initialized to the values set with the support tool when the NT620S/620C is
switched OFF.
If the message “Battery Lowered” is displayed while the NT620S/620C is oper-
ating, replace the built-in battery immediately. For details on how to replace the
battery, see “Replacing the Battery” (page 275).
The memory switches can be set easily by using the memory switch menu in the
System Menu.
The memory switches can also be set by selecting “In.Scr” [F8] on the “File
Selection” screen of the support tool. The settings made using the support tool
are written to the NT620S/NT620C on screen data registration. For details, refer
to the NT-series support tool operation manual (V028-E1).
The settings that can be recorded for the memory switches are shown below. For
details on each function, see the next section and 3-8 “Various System Settings”

Registering the Screen Data Section 3-6
The NT620S/620C uses several screens which are switched on its display. The
screen data of one NT620S/620C unit corresponds to the files created by using
the support tool. Select a file which contains the screen data to be transmitted
when selecting the screen data to be transmitted to the NT620S/620C so that the
required screen data can be transmitted to the NT620S/620C.
When screen data is transmitted from the support tool to the NT620S/620C, all
existing screen data in the NT620S/NT620C is deleted.
If an error message and the System Menu are displayed immediately after the
NT620S/620C has been started, the screen data memory needs to be initialized.
To transmit the screen data from the support tool to the NT620S/620C, connect
the NT620S/620C to the computer on which the support tool is being used, and
follow the procedure below.
Reference - When screen data transmission is performed, the NT620S/620C screen data
memory is automatically initialized before the new screen data is transmitted.
There is therefore no need to initialize the screen data memory using menu
operations before transmitting the screen data.
- The NT620S/620C uses the same connector for screen data transmission and
connection to the PC. If the NT620S/620C is currently connected to the PC,
disconnect the PC cable and connect the support tool (personal computer)
cable to this connector before attempting screen data transmission.
77

Note Press the “Abort” touch switch on the NT620S/620C when the screen data
transmission is completed. Unless this touch switch is pressed, the screen data
will not be correctly registered. If the “Abort” touch switch is pressed during
transmission, the screen data will not be correctly registered.
If screen data cannot be transmitted from the support tool properly, check wheth-
er communication between the NT620S/620C and support tool (personal com-
puter) is normal.
To check communication with the support tool, use the “Tool Transmit” function in
the maintenance mode of the NT620S/620C. See “Checking the Communica-
tions with the Support Tool” (page 98).
Precautions to be Observed During the Screen Data Transmission
When any of the following or a system error occurs during the screen data trans-
mission, the transmitted screen data will not be registered correctly to the
NT620S/620C. If an error message is displayed in the System Menu and the
Transmit Mode cannot be selected, the screen data memory needs to be initial-
ized.
S The power to the NT620S/620C is interrupted or the NT620S/620C is reset.
S The power to the computer on which the support tool is running is interrupted or
the computer is reset.
S The cable connecting the NT620S/620C to the computer on which the support
tool is running is disconnected or has a broken wire.
S The “No” touch switch on the NT620S/620C screen is pressed to end the trans-
mission during screen data transfer.
S The “ESC” key on the support tool is pressed to end the transmission.
When the power to the NT620S/620C is turned ON or reset, the screen data is
checked. However, if any of the above occurs during the screen data transmis-
sion, the screen may disappear and other unexpected problems may occur.
In the case of such problems, set DIP SW2-1 to ON to initialize the memory.
79
Starting the Operation Section 3-7
For the memory initialization by using the DIP switch, refer to the “Initialization by
using the DIP switch” (page 65).
Reference The start-up screen is the screen whose screen number is set for the screen
switching specification in the PT status control area. If no screen data has been
registered at screen number, the “Screen not registered.” error message will be
displayed. For the screen number setting, refer to Section 4-3 “Screen Display”
(page 129).
80
Various System Settings Section 3-8
Reference If the memory switch data is not backed up by the built-in battery, it will all be

Screen Management All screens displayed on the NT620S/620C are managed by their screen num-
bers.
A screen number can be assigned at the time of the creation of a screen by the
use of the support tool. Up to 2000 screens can be created, and screen numbers
from 1 to 2000 can be given to each of them as desired. The screen number is
very helpful in switching the screen being displayed to a desired one from the
host, or in specifying the screen to be displayed at the startup of the system (ini-
tial display screen).

screen or drawing them on the screen when creating screen data. All data dis-
played on the entire screen can also be registered as image data.
Image data
Part of another
screen can be
cut and dis-
played.
Image data
An image drawn
on the screen
can be displayed.
Image data of up to 224 images can be registered in a screen data file as code
of FE20 to FEFF.
Basically, image data can be displayed in any position on the screen, however,
the entire image may not be displayed in some specific positions.
• Library data (Ver.3 direct connection or later version)
Library data is image data consisting of plural characters and graphics.
The size can be specified within the following range of rectangular areas.
NT620S : Min. 1 1 dot to Max. 640 400 dots (entire screen)
NT620C : Min. 1 1 dot to Max. 640 480 dots (entire screen)
The creation of library data starts by laying out characters and graphics with
attributes on the screen in the same manner as regular screen data.
Next, specify the area to be registered. Only characters and graphics can be
extracted from other screen data and registered as library data.
Library data cannot be registered as display elements.
Library data
Even complicated
data can be
displayed.
124
Outline of Functions Section 4-2
Basically, library data can be displayed in any position on the screen. But, in a
position where the entire library data cannot be displayed, it automatically
moves to another position. Use care in setting a display position.
• Smoothing
Characters (or marks) enlarged to x4 scales or larger are displayed with the
outline automatically smoothed. This function is called “smoothing”. Image
data and library data cannot be smoothed.

The color of the boundary line surrounding the area to be filled is the outline
color.
Background color
Part of the graphic frame may be invisible because of the combination of the
display (in filling), background and outline colors. This phenomenon is peculiar
to a color LCD, not a failure with the system.
In such a case, change the color combination.
• Reverse and flashing display
Normal display: Only the outline of a graphic is displayed in a
designated color.
Reverse display: A graphic filled in the same color as that of the
graphic outline is displayed.
Flashing display: Normal display alternates with no-display.
Reverse and flashing display: Normal display alternates with reverse dis-
play.
Polylines and arcs cannot be inverted, flashed or inverted and flashed alter-
nately.
Filling can be designated only with normal display.
Note Do not fill graphics to which a flashing display or inverse flashing display attrib-
ute has been set.
If a graphic with a flashing display or inverse flashing display attribute is to be
filled, the area outside the graphic may be filled in the same pattern when the
system operates.

The NT620S/NT620C can communicate with a PC by using the host link/NT link.
Using the host link/NT link, bits and words can be allocated to any area in the PC
memory and data can be written to and read from these bits and words directly.
This makes the following functions possible:
Screen switching
For details on the actual operations required for these functions, refer to Section
5 “Using Host Link/NT Link”.
For details on the actual methods used for these types of control with the
NT620S/NT620C, see Section 5-7 “NT620S/620C Status Control” (page 234).
Numeral setting input: Whether a numerical value has been input with a
numeral setting

% Value can be calculated according to the following equation:
Referred Numeral Memory Table value – 0% Value
% Value = 100
100% Value – 0% Value (or 0% Value – (–100% Value))
Attribute of numeric value displayed is the same as that for character display.

Graphs Section 4-5
For a trend graph, a single graph frame can be shown in a screen and a maxi-
mum of 50 graphs can be registered in the graph frame.
• Reference table
This is the same as for bar graphs. See page 138.
Although it is possible to select either “direct” or “indirect” as the reference
method with the support tool, only the “direct” setting is meaningful when using
an NT620S/NT620C.
It is not possible to use hexadecimal values for trend graphs. If hexadecimal
values are specified in numeral memory tables referenced to obtain graph val-
ues, the graph will not be displayed. The letter “F” may be used to indicate neg-
ative values, but make sure that no hexadecimal values are written.
Trend Graph Attributes When using an NT620S/NT620C, the following attributes can be used when dis-
playing trend graphs.
• Graph frame
This attribute specifies a rectangular area used to display a graph.
This area can occupy the following range:
NT620S: Max. 640 dots horizontally x 400 dots vertically
NT620C: Max. 640 dots horizontally x 480 dots vertically
The following setting can be performed for a graph frame.
- Frame display
With the “Frame Display” specified, 1-dot width frame line is displayed out-
side of the frame area. When using an NT620C, color of a frame line can be
selected out of eight colors.
- Background color in a frame: 8 colors (NT620C only)
141
Graphs Section 4-5
Separate background color can be specified for positive and negative value
display area.
• Displaying method
A graph displaying method can be selected out of two types: normal type and
pen recorder type.
- Normal type
As time goes by, the latest data display position moves toward the direction of
increase. When the displacement increases to the right, a graph varies as
shown below. When a polygonal line reaches the end of a screen, it is
cleared once and the NT610C starts drawing a polygonal line again from the
first.

• Sampling period
Sampling period is the time interval applied when the NT610C samples and
displays the Numeral Memory Table value and is specified in the range of 1 to
65535 in increments of 0.1 second.
Reference Actual drawing timing varies depending on the operating conditions. This does
not accurately coincide with the time interval specified.
• % Data value
The same is also true as the bar graph. Refer to page 139.
• Graph line type
This attribute specifies a graph line type among those as shown below. A
graph width is fixed at one dot. Line color can be selected out of eight colors.

–100%
A value is displayed in a graph in the same way as (2) at the % display posi-
tion depending on the presence of a sign as follows:
• When the graph width is not an integral multiple of the drawing width
In the normal type, when a graph is over the graph frame next time, the
NT610C draws a graph of the latest data at the end of the frame.
< Example: In case the graph width 100-dot and the drawing width 30-dot >
100-dot

Reference If a graph is duplicated by drawing multiple graph lines of the same % value, it is
overwritten and displayed in the order of setting. Similarly, when 0% value
continues in a graph with a sign displayed, a graph line is overwritten and
displayed with respect to the graph frame indicating 0%.

For a broken line graph, a single graph frame can be shown in a screen and a
maximum of 256 graphs can be registered in the graph frame. A single broken
line can display a maximum of 512 Numeral Memory Tables. However, the maxi-
mum number of numeral memory tables that can be displayed on one screen is
also 512.
• Reference table
Specifies the first memory table number of the series of referenced memory
tables.
It is not possible to use hexadecimal values for broken line graphs. If hexadeci-
mal values are specified in numeral memory tables referenced to obtain graph
values, the graph will not be displayed. The letter “F” may be used to indicate
negative values, but make sure that no hexadecimal values are written.
When using an NT620S/NT620C, the following attributes can be used when dis-
playing broken line graphs.
• Graph frame
This attribute specifies a rectangular area used to display a graph. This area
can occupy the following range:
- Frame display
With the “Frame Display” specified, 1-dot width frame line is displayed out-
side of the frame area. Color of a frame line can be selected out of eight col-
ors.
Separate background color can be specified for positive and negative value
display area.

100% position is determined in accordance with the direction of putting the re-
ferring Numeral Memory Table values in order. 100% position falls to the right
when putting those values longitudinally in order and at the upper side when
putting those laterally.
• Sign representation
This attribute can specify whether or not a numeric value less than 0% value is
displayed.

• Number of apexes
This specifies the number of Numeral Memory Tables to be referred to. One
apex indicates a single Memory Table value.
Since a minimum of one dot width is required to display one Memory Table val-
ue as a polygonal line, maximum number of Memory Table capable of referring
in accordance with a graph frame width is determined by the following equa-
tion.

Reference - If a graph is duplicated by drawing multiple graph lines of the same % value, it
is overwritten and displayed in the order of setting. At this time, since the part
that the lines are duplicated is displayed by use of those colors of the Exclusive
OR display (Refer to page 121), the line type and line color are displayed dif-
ferently than that specified.
- Since a graph line is overwritten with respect to the graph frame when 0% value
continues in a graph with a sign displayed, line type and line color are displayed
differently than that specified.
- When creating a graph, apexes of polygon are placed in order at regular inter-
vals within the frame width. Apex interval can be changed freely when correct-
ing a polygonal line.
4-6 LAMP
Lamp is a graphic area capable of changing the displaying state according to an
instruction from the PC. There are two kinds of LAMPs: Normal LAMP that chan-
ges the displaying state (OFF, ON, Flashing) of a graphic fixedly displayed and
Image Library LAMP that displays separate graphics in OFF and ON states.
LAMP is set when creating a screen data with the Support Tool.
A maximum of 256 LAMPs can be set in a screen, and 1024 LAMPs can be regis-
tered in a screen data file.
Contents of the setting differs depending on the LAMP type (Normal LAMP,
Image Library LAMP).

Numerical Values that can be Input and Attributes that can be Set
Numeral values up to 8-digit (up to 7-digit for negative numbers) can be entered
in decimal and hexadecimal notation.
• Entry of decimal number
When the display attribute is set to decimal number display, a numeral value
can be entered in decimal.
- Range of numeral values
Range of numeral values that can be entered differs depending on a sign.
With a sign not displayed: 0 to 99999999 (8-digit)
With a sign displayed: –9999999 to +99999999 (7-digit negative num-
ber, 8-digit positive number)
For a thumb wheel type, numeric values are up to 7-digit for both positive and
negative numbers with signs displayed.
- Decimal point
To the right of the decimal point, a maximum of 7-digit can be entered (up to
6-digit for negative numbers).
• Entry of hexadecimal number
When the display attribute is set to hexadecimal number display, a numeral val-
ue can be entered in hexadecimal.
Range of numeral values
Range of numeral values that can be entered is from 0 to FFFFFFFF (8-digit).
158
Numeral Setting Section 4-8
When the upper limit and lower limit of the input numeral values have been set,
erroneous numeral values outside of the range can be prevented from being
stored in the numeral memory table or notified to the host.
Caution When the numeral values entered are confirmed, upper/lower limits are
checked. Otherwise the system may operate unpredictably.
A maximum of 50 input fields (combined total for both numeric key type and
thumb-wheel type) can be registered on one screen.
Ten-key Type When any numeral value is entered by the ten-key (character key) assigned to
the touch switch, a numeral value just entered is displayed in a screen. When the
RETURN key is pressed after an input operation is completed, the numeral value
entered is written into the numeral memory table and then notified to the PC.
When there are multiple numeral setting input columns, a numeral setting input
column for input operation is also selected by the ten-key.
To use the ten-key type, it is necessary to create not only the numeral setting in-
put column in a screen but also the ten-key for input operation (Refer to page
160).

A numeric value cannot be entered into the thumb wheel type from the ten-key.
• Changing signs
In case of sign display setting, the sign “+” is specified by touching the “+” key of
the digit for which the sign is displayed and the sign “–” by touching the “–” key.
• Checking the upper/lower limits
Upper/lower limits are checked when pressing the increment/decrement (+, –)
keys. If it is found that an input numeral value is in excess of the limit as a result
of checking, the contents of the numeral memory table (previous value before
pressing the increment/decrement (+, –) keys) is displayed again, but this is
not notified to the Host.
However, with thumbwheel type numeral setting, if the situation is such that
with an upper limit of 1n..n, and a lower limit of 0m..m (where n and m are the
values of each digit), n..n < m..m, it is not possible to carry digits upward or
downward.
Example:
When the upper limit value is 1200 and the lower limit value is 201, if the initial
value has three digits the value can be changed within the range 201 to 999,
and if the initial value has four digits it can only be changed within the range
1000 to 1200.
This is because if an attempt is made to change the leftmost digit from 0 to 1, or
from 1 to 0, an upper/lower limit value check is always performed.
In order to avoid this, either set the values so that n..n x m..m, or create anoth-
er touch switch and write values to it when digits are carried up or down.

Reference - By using the pop-up window function (see page 171), it is possible to select
and open a number of windows (keypads), each of which comprises a number
of character keys, thus allowing various types of input.
- Input to character-string setting input fields can be disabled by a system control
(PT status control area) operation.
How to Enter the Character-Strings
An appropriate character-string setting input column is specified to be ready for
an input operation before a character-string is entered by the character key.
• Specifying the character-string setting input column to be entered
The character-string setting input column to be entered is specified by either
ten-key, system key, or touch switch (cursor moving key).
The frame (cursor) around the specified character-string setting input column
and the cursor attributes can be specified.
Concrete specifying method is the same as numeral setting. Refer to the
“Specifying the Numeral Setting Input Column to be Entered” (page 162).
Reference The window opening function can be set for cursor moving keys. For details, see
4-10 “Pop-Up Window Function” (page 171).
• Entering the character-string
The character-strings are displayed in the input column of the character-string
setting in due order of the touch switches being pressed (A character is in-
serted at an input cursor position). At this time, the keyboard screen can also
be switched over halfway.
When entering the character-strings, the following control keys of the touch
switches can be used.
169
Character-String Setting Section 4-9
Reference - It is also possible to use the control keys of the input key function (however, the
four keys used for alarm display cannot be used).
- By switching between windows, a large number of character keys can be used.
It is also possible to create a temporary input field in a window to allow the exist-
ing data to be checked while inputting new data. For details, see 4-10 “Pop-Up
Window Function” (page 171).
- Using copy keys (page 156) allows you to input the value or code (constant)
stored in a character-string memory table into a character-string setting input
field in a one-touch operation.
Example:
- When the “NT620S-” is pressed
NT620S- NT620C-

- Finally, when the Enter ( ) key is pressed, the “NT620S-ST211” being dis-
played in the input column of the character-string setting is confirmed and
written into the character-string memory table and simultaneously notified to
the PC.

Using the pop-up window function, windows can be created in the screens num-
bered 1900 to 1979 (note that a screen for which a window is registered is called
a “window screen”). Screens other than these cannot be opened as windows.
On returning to the “Screen List” screen after creating a window in the screen
number range 1900 to 1979, specify the “window area (display area)” (The win-
dow will then open in a display area of the specified size and at the specified posi-
tion).
- Fixed displays
- Touch switches (but the input notification and screen print functions cannot
be used)
Elements that project beyond the display area will not be displayed when the win-
dow opens. Similarly, display elements on the base screen that overlap even
partly with the window will be deleted when the window opens.
Note - Since the pop-up window function and screen print function share the same
memory area, it is not possible to open a window during screen printing. Con-
versely, a screen cannot be printed while a window is open.
- The display elements in a window cannot be notified to the PC. This means
that the lamp bits of touch switches in windows cannot be controlled.
- While a window is open, display processing may be slightly delayed.

Opening Windows with the Cursor Moving Keys
It is possible to set a window key “open” function for the cursor moving keys used
for numeral/character-string setting, in addition to their cursor moving function.
Doing this makes it possible to specify an input field and also display the window
to be used in a one touch operation.
If another window is open when the cursor moving key is pressed, that window is
closed first before the specified window is opened (the cursor also moves to the
174
Pop-up Window Function Section 4-10
specified input field). If the specified window is already open, the cursor moves to
the relevant input field but nothing else happens.

touch switch.
However, if the temporary input field in the window and the input field on the base
screen are not of the same type, the temporary input field will not be displayed.
Note also that temporary input fields cannot be used for thumb wheel type input
fields.
The temporary input field will also be unusable and not displayed if it has fewer
digits than the actual input field on the base screen (number of integer digits +
number of decimal fraction digits + digit for decimal point + digit for sign).
If it is not possible to use a temporary input field, the data has to be input directly
onto the base screen.

(1) Specify the numeral/character-string input field used for actual input with a
numeric key, system key, or touch switch (cursor moving key).
The actual method used for specification is the same as that for numeral set-
ting. See “Specifying the Numeral Setting Input Column to be Entered”
(page 162).
(2) If the window in which the temporary input field is registered is not displayed,
open it (this could also be done prior to step (1)). For the method for opening
the window, see “Opening and Closing Windows” (page 174).
The temporary input field displays the contents of the actual input field at that
point in time. The display of the temporary input field is governed by the fol-
lowing attributes:
- Attributes determined by the settings for the actual input field on the base
screen:
Numbers of integer and decimal fraction digits, upper limit value, lower
limit value, decimal/hexadecimal, zero suppress, sign display.
(3) Input the numerical value or character-string. The method is the same as
that normally used to input numerical values and character strings. See “En-
tering the Numeral Values” (page 164), or “How to Enter the Character-
Strings” (page 169).
(4) The input numerical value of character-string is written to the input field on
the base screen on confirming it by pressing the ENT key or the return key
( ), and the contents of the corresponding numeral/character-string
memory table are changed accordingly (notification to the PC also takes
place at this time). The cursor moves to the next input field on the base
screen.
If the input value is outside the range delimited by the upper and lower limit
values, the original value is redisplayed.
Note also that if the actual input field on the base screen is changed before
input is confirmed, the input data will be destroyed. The input data will also
be destroyed if the window is closed or the screen is switched before con-
firmation.

Example:
When the contact corresponding to the message being displayed returns to “0”
(OFF), the message and image library is cleared and the next message is dis-
played according to the order of priority.
• Scrolling the message
When the message issued extends more than the number of lines set to mes-
sage display, the message being displayed can be scrolled in unit of line or
page.
When the number of lines for message display is set to four or more, the control
keys for scrolling are automatically created as shown below.

When the number of lines for message display is set to one to three, only line
scrolling keys are automatically created.
The scrolling key can also be set and corrected by the “Control” out of the “Input
Key” functions of the touch switches.
• Scrolling keys shown in reverse video
179
Alarm List & History Display Functions Section 4-11
Since these scrolling keys are automatically shown in reverse video when
there are any messages in front or behind those keys, it is found whether or not
there are any messages that are not displayed.
Switching the Image Library to be Displayed
The message display column also serves as a touch switch. By selecting the
message (touch switch) displayed, corresponding image library can be dis-
played.
Switching over to the Corresponding Screen
To the bit memory table used for the alarm list display function, corresponding
screen number can be set, as well as corresponding character-string memory
table (message) and image library.
When the screen number has been set, by pressing the message once again that
is being selected in the section above “Switching the image library to be dis-
played”, it is possible to switch over to and display that screen.
Example:
Message
Setting the Alarm List Display Function (Setting the Bit Memory Table)
When the alarm list display function is used, it is necessary to set the bit memory
table and screen display function. This paragraph describes the setting of the bit
memory table. For the display setting, refer to NT-series Support Tool
Operation Manual” (V028-E1-01).
In order to set the message to continuous or duplicate screen, only the first sub-
screen is effective.
In one alarm group, the bit memory tables less than continuous 128 can be used
and the state of up to 128 contacts can be monitored. The smaller the bit memory
table number, the higher the order of priority a massage has.
The following settings are done to each bit memory table.
• Recording the alarm history
Setting of whether or not a change of PC contact to which the bit memory table
is assigned is recorded.
• Screen switchover function
Setting of whether or not the screen switchover function is used.
• Character-string memory table number
Character-string memory table number displayed as a message is set.
• Display color (NT620C only)
Character color of a message is set.

Alarm List & History Display Functions Section 4-11
• Image library
Code of image library data displayed together with a message is set.
• Screen switchover
Screen number displayed by the alarm list and history display function is set.
• Contact
Contact on the PC, to which the bit memory table is assigned, is set.
f: OK : NG
The Auxiliary Relay area of CVM1/CV series PC is used exclusively for special

For the alarm history, the following data is recorded in the memory concerning
the contact that turns “1” (ON).
- Contact number
- Message set in the bit memory table (the contents of the character-string
memory table)
Data recorded is backed up by a battery, so it is not lost even when the power
supply is turned OFF.
Reference When the voltage of the battery in the NT620S/NT620C drops, the recorded
data cannot be retained reliably.
How to deal with alarm recording in the order of occurrence when the number of
alarms capable of being recorded is exceeded is determined by the “Alarm First-
in First-out” setting of the “System Memory” of the support tool as follows:
In order to clear (initialize) the alarm history, the memory is initialized (Refer to
page 67).
The alarm history can also be cleared using bit 11 of the “PT status control bits.”
(Refer to page 237.)
The alarm history can be displayed by the NT620S/620C during operation by set-
ting an area and displaying method when creating a screen data with the support
tool.
There are two displaying methods: in the order of occurrence and frequency.
• In the order of occurrence
The alarm history is displayed in the order that a contact becomes “1” (ON). As
more detailed information, date and time of occurrence can be displayed si-
multaneously.
182
Alarm List & History Display Functions Section 4-11
• In order of frequency
The alarm history is displayed in the order of frequency that a contact becomes
“1” (ON). Number of occurrence is displayed simultaneously.
For both order of occurrence and order of frequency, the maximum number of
entries that can be displayed is 16 in the case of the NT620S and 24 in the case of
the NT620C. When the alarm history is set, the scrolling keys are created auto-
matically. Creating and using the scrolling keys are the same as the alarm list
display. Refer to the “Scrolling the message” (page 179). Displaying the image
library and switching over the screen are the same as the alarm list display. Refer
to the “Switching the Image Library to be Displayed” and “Switching over to the
Corresponding Screen” (page 180).
The alarm history can be displayed simultaneously in the order of occurrence
and frequency in one screen, respectively.
The alarm history display function does not automatically update the contents of
display even when the state of contact is changed during displaying operation.
The contents of display is updated when pressing the scrolling keys.

dix L “PC Memory Map” (page 327).
Note Make the allocations so that there is no duplication between the PT status con-
trol area and the PT status notify area.
Notifying the Display Elements by Using Allocated Bits and Words
The NT620S/620C will operate as follows in the display element notification op-
eration.
[NT620S/620C operation]
The NT620S/620C will write any changes in the contents of the numeral or char-
acter-string memory table being displayed or pressing of a touch switch to the
bits and words area in the PC.

Notifying the NT620S/620C Status by Using Allocated Bits and Words ..... PT Status Notify Area (PT to PC)
The PT status notify area (PT to PC) is provided to notify the NT620S/620C sta-
tus changes to the PC. When any NT620S/620C status has changed, such
change is written to this area in the PC, and the PC will read the data from this
area to check the NT620S/620C status.
The PT status notify area is configured as three consecutive words as shown be-
low.
Word 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 Bit

m+2 PT status 0 0 0 0 0 0 0 PT status
The first word (word m) of the PT status notify area must be set with the support
tool.
S Currently displayed screen (refer to page 195)
The screen number displayed on the NT620S/620C is written to this word.
Simultaneously, the PT status screen switch strobe flag is set to ON (1). After
this is notified to the PC, this flag reverts to OFF (0). Checking the status of this
flag will provide a simple method of checking if the NT620S/620C display has
switched.
S Content upgrade memory table (refer to page 220)
The number of the numeral or character-string table is written to the word when
the numeral or character-string memory table contents change due to the
touch switch operation on the NT620S/620C. (The contents of the word to
which the numeral or character-string table has been allocated also change.)
189
Outline of Host Link/NT Link Operation Section 5-1
As the number of the numeral table is written, the PT status numeral or charac-
ter-string setting strobe flag is simultaneously set ON (1). After this is notified to
the PC, this flag reverts to OFF (0). Checking the status of this flag will provide
a simple method of checking if a number or character-string has been input
from the NT620S/620C.
S PT status notify bits (refer to page 240)
The NT620S/620C operation status and other information are written with the
ON or OFF of the bits as shown below.

Since the special auxiliary relays of the CV series PCs are allocated to the sys-
tem, they cannot be used for purposes other than system use.
The range of respective area varies with the type of PC. Refer to Appendix L
“PC Memory Map” (page 327).
Procedure 1. Use the support tool to set the following for the following for a bit memory
table: a screen switching function, the screen number of the screen to be dis-
played, and the area of the PC to which the bit is to be allocated.
2. At the PC, write the program that will switch the allocated bit from OFF to ON
and switch the screen display.
In cases such as that where a warning screen is to be displayed when a par-
ticular bit is turned ON, there is no need to write a program; it is sufficient just
to set the allocated bit.
The NT620S/620C screen switches when the allocated bit of the bit memory
table changes from the “0” (OFF) to “1” (ON) status. However, the display does
not change when the allocated bit returns from the “1” (ON) to the “0” (OFF)
status.

When bit 001000 comes ON, the NT620S/620C displays screen No. 1000.
This processing reads the data from the PC status notify area.
To indicate that the screen has switched, use the screen switch strobe flag.
To display the number of the currently displayed screen, use the currently dis-
played screen word.
When the screen has switched, the NT620S/620C notifies the following to PT

were added to the contents of memory table 20 to give 52, the contents of
memory table 52 would be displayed instead.
The memory tables used for display can also be allocated to areas in the PC, so
that the display can also be changed in response to changes in the data to be
displayed (i.e., the contents of character-string memory table 51 in the example
above).
However, in comparison with direct specification, indirect specification requires
more time for processing.
Setting the Words of the Character-String Memory Table
When creating the screen data by using the support tool, make the following set-
tings for each numbered character-string:
S Initialization setting
Set whether or not the PC words are initialized with the character-string
memory table initial value registered to the screen data memory when the main
power supply is turned ON or reset.
S Number of registration words
Set the number of words within 20 words required for registering the character-
string data. One word can store two characters.
S Setting the words for the character-string memory tables
The character-string memory tables can be allocated to the following PC
words. Set the word type and the first word.
199
Memory Tables and Graphs Section 5-2
There are two methods for referencing numeral memory tables used for numeral
display, as follows:

If the hexadecimal data (A to F) are stored when the decimal display has been
set, the alphabets are displayed.
If the most significant digit is “F” when “decimal with signs” has been set, the
numeral is handled as a negative number. The maximum number of digits of
the negative number becomes smaller than that of the positive number by 1
digit.
Reference - If the number of digits of a numeral is greater than the total of the settings for
the number of digits of the integral portion and the number of digits of the deci-
mal portion, an error will be generated and “:” symbols will be displayed at all
digits. If the number of display digits is not 4 and “:” symbols are displayed,
check that the number of words in the numeral memory table is 1.
The actual display will vary according to the “zero suppress” setting and deci-
mal fraction setting as well as the contents mentioned above. Refer to the “NT-
series Support Tool Operation Manual” (V028-E1-02).

This method is convenient when switching the display at the same location, for
example when monitoring a series of words, or when using unique codes to
specify individual character strings, etc.
Procedure 1. Set the PC area for the numeral memory table to be used for indirect specifi-
cation of numeral/character display using the support tool. Set the number
(i.e., the number of words) of the numeral memory table to 1.
2. When creating the screen data with the support tool, register for the screen
the numeral memory table referenced in indirect specification. Set “Indrct”
for “Ref way”.
For a character-string, specify the numeral memory table by using the “char-
acter display” function of the support tool.
For numerical values, specify the numeral memory table by using the “nu-
meral display” function of the support tool.
3. Using the “table edit” function of the support tool, write the data to be dis-
played to the memory table which is used for display. Use a numeral memory
table to display numerals and use a character-string memory table to display
character-strings.
4. Create a PC program to change the contents of the word allocated to the nu-
meral memory table which is used in indirect specification.
S Important points when writing memory table numbers
When writing the number of the memory table whose contents are to be dis-
played to the numeral memory table to be referenced in indirect specification,
206
Memory Tables and Graphs Section 5-2
always specify this number in BCD format. Also make sure that you do not
specify a number outside the range of memory table numbers that actually ex-
ist (for example by specifying “0500” when the number of character-string
memory tables is set to 256).
If the contents of the memory table used for indirect specification are written in
hexadecimal format, or if the specified memory table number is outside the
available range, the display will not be updated.
S Important points when writing character-strings
The important points when displaying character-strings are the same as those
that apply for indirect specification. See the “Important points when writing
character-strings” when using direct specification (page 204).
Example of Changing a Character-String in Indirect Specification
An example in which the character-strings being displayed are changed by ad-
ding the contents of the word allocated to the numeral memory table which is
used in indirect specification is given below.
S Setting by the support tool
Perform the following setting with the support tool.
Numeral memory table number 51: DM0000 (registration word: 1)
Character-string memory table number 100: NT612G (6 digits)
Character-string memory table number 101: NT610C (6 digits)
Character-string memory table number 102: NT620S (6 digits)
Character-string memory table number 103: NT620C (6 digits)
Contents to be registered for the screen: Numeral memory table number 51
Line 1

S Program operation
(1) Each time contact 00100 comes ON, the display on the NT620S/620C
changes to the next item in the following sequence.
NT612G → NT610C → NT620S → NT620C
(2) Each time contact 00101 comes ON, the display on the PT changes to the
next item in the following sequence.
NT620C → NT620S → NT610C → NT612G
In this example, the contents of numeral memory table 51, which is referenced
using indirect specification, are not checked. When actually using the pro-
gram, make sure that the contents of numeral table No. 51 are not outside the
range 0100 to 0103.
NT620S/620C PC
Write a memory table number etc. to the copy memory table setting area in the
PT status control area in the PC memory. Data will be copied between the
memory tables in the NT620S/620C and the displayed value will change accord-
ingly.
This procedure is convenient to switch predetermined values or character-
strings according to the situation. By preparing several units of contents, various
contents can be displayed by switching them to suit the situation.

S Use of the “copy type”
Copy will not be executed when the “copy type” is other than “0” or “1”. The
memory table copy is executed only when the contents of the area are
changed. To repeat copying of the same copy source and same copy destina-
tion, write a value other than “0” or “1” for the copy type, and then, write a cor-
rect value again.
S Copying a numeral memory table
If the display method or the number of registered words include discrepancies,
a numeral memory table may not be copied and displayed correctly.

To change the lamp display status on the NT620S/620C, turn ON and OFF the
lamp control bit allocated in the PC.
NT620S/620C PC
0 (OFF): Unlit
1 (ON): Lit (reverse display) or flashing
Procedure 1. Use the support tool to set the PC memory area where the lamp control bit is
to be allocated to.
2. Register the lamps to the screen when creating the screen data by using the
support tool.
Use the support tool to set the lamp display attributes whether the lamp is lit
or flashing when the lamp control bit is turned ON.
With the NT620S/620C, it is possible to set lamps that display any required
image or library data in their lit status and in their unlit status. For details, see
“Image Library LAMP Setting” (page 151).

In order to notify the status of a touch switch to the PC, the touch switch must be
allocated to a specified PC bit so that it can be managed. Designate the area and
bit number.
To use touch switches for notification to the PC, the following settings must be
made using the support tool: “touch switch” – “bit setting” – “notify bit”.
S Types of notification operation
When using Ver.2 or a later version of the direct connection function, it is pos-
sible to select one of four types of notification operation that occur when the
touch switch is pressed (with Ver.1 of the direct connection function, the setting
is fixed as “momentary”).
214
Lamps and Touch Switches Section 5-3
- Momentary
When the touch switch is pressed the bit comes ON and when it is released
the bit goes OFF.
- Alternate
When the touch switch is pressed the bit comes ON if it is OFF and goes OFF
if it is ON.
- Set
When the touch switch is pressed the bit comes ON, and it remains ON when
the touch switch is released.
- Reset
When the touch switch is pressed the bit goes OFF, and it remains OFF when
the touch switch is released.
When using touch switch input notification, note the following points.
- In the case of (1) in the table, the other bits in the same word are turned OFF
by notification.
- In the case of (2) in the table, since notification is executed on the basis of the
contents of the word before display, the other bits in the word are not overwrit-
ten. However, if the contents of the word are changed at the PC during dis-
play, they will be rewritten based on the contents before display.
- If the screen is switched while a momentary key is pressed, the touch switch
itself will disappear and the “OFF” status will be notified to the PC. This
means that, in the case of (1) in the table, all the bits in the word will be set to
the “OFF” status.
- When using the host link, or when using the NT link with the DM area, the
notification operation is different for the momentary type and the other types,
and they should not both be specified in the same word.
In the case of (3) and (4), notification has no effect on the other bits in the word.

Touch switch 1
The status of the lamp bit reflects the touch switch status, as follows:
0 (OFF): Unlit
1 (ON): Lit (inverse display) or flashing
Procedure 1. Use the support tool to allocate the touch switch lamp bits to the PC memory.
2. When creating the screen data using the support tool, register the touch
switch for a screen.
3. Create the PC program to switch the lamp bit of the touch switch ON and
OFF.
Set whether a touch switch will be continuously lit or blink when its bit has
been turned ON by setting the support tool touch switch display attributes.
216
Lamps and Touch Switches Section 5-3
The status of the notify bit reflects the touch switch status, as follows:
Momentary: 0 (OFF) . . Not pressed
1 (ON) . . . Pressed
Alternate: The allocated bit is switches to 1 (ON) if currently 0, and to 0
(OFF) if currently 1.
Set: The allocated notify bit is forcibly switched to 1 (ON).
Reset: The allocated notify bit is forcibly switched to 0 (OFF).
The status of a touch switch is determined by checking the ON/OFF status of its
notify bit.
The touch switch notify bits can be allocated to the following areas of the PC
memory.
217
Lamps and Touch Switches Section 5-3
S Important Points
Details on touch switch notification operations are tabled below.
When using touch switch input notification, note the following points.
- In the case of (1) in the table, the other bits in the same word are turned OFF
by notification.
Press the
touch switch
Bit 15 14 1 0 Bit 15 14 1 0
0 1 0 1 0 0 1 0
In the case of (2) in the table, since notification is executed on the basis of the
contents of the word before display, the other bits in the word are not overwrit-
ten. However, if the contents of the word are changed at the PC during dis-
play, they will be rewritten based on the contents before display.
- If the screen is switched while a momentary key is pressed, the touch switch
itself will disappear and the “OFF” status will be notified to the PC. This
means that, in the case of (1) in the table, all the bits in the word will be set to
the “OFF” status.
- When using the host link, or when using the NT link with the DM area, the
notification operation is different for the momentary type and the other types,
and they should not both be specified in the same word.
In the case of (3) and (4), notification has no effect on the other bits in the word.
Application This example uses the touch switches as normal switches (bits) in order to use
the NT620S/620C as an operating panel.

5-5-2 Displaying Alarm Lists (by Using Bit Memory Table Allocation)
This section explains the actual procedure used to display the alarm messages
of the alarm list function on the screen of the NT620S/620C.
In order to display an alarm message, the allocated bit of the bit memory table
allocated to the PC has to be switched ON.
NT620S/620C PC
The relationship between the status of the allocated bit of the bit memory table
and the corresponding alarm message is as follows:
0 (OFF): Deleted
1 (ON): Displayed
Procedure 1. Select “TBL EDIT” from the support tool editing menu, set the allocated bit of
the bit memory table in the PC area, then set the corresponding alarm mes-
sage.
2. When creating screen data with the support tool, register the alarm list speci-
fied by the bit memory table in (1) above for the screen.
3. Create the PC program to switch the allocated bit of the bit memory table ON
and OFF.
S Image/library data corresponding to alarm messages
Apart from alarm messages, image/library data can also be set for bit memory
tables. The alarm list is composed of touch switches and touching (pressing)
an alarm message will display the corresponding image/library data for your

Clock Function Section 5-6
Procedure 1. Allocate the two memory tables that are to be the copy source for the setting
to areas in the PC.
Two words must be allocated for each table.
2. Next, at the PC, specify the date and time that are to be set in numeral
memory tables 254 and 255 in these allocated words.
3. Copy the settings from the copy source numeral memory tables to numeral
memory tables 254 and 255.
For the method for copying memory tables, see “Copying the Memory Table”
(page 208).
S Important points concerning the numeral memory tables used for the clock
function
Do not allocate the numeral memory tables to which the clock function is as-
signed (numbers 247 to 255) to PC words.
Numeral memory tables 247 through 253 are exclusively for display (read
only). Do not attempt to write data to them by using numeral settings or by co-
pying between memory tables.
Numeral memory tables 254 and 255 are exclusively for time setting (write
only). Do not use them for numeral displays or graph displays.
Initial values set with the support tool are invalid in the case of numeral memory
tables 247 through 255.
Date and Time Setting Example
The following is an example of setting the date and time from the PC.
In this example, a C200H (type C200H-CPU11,21,22,23,31) which has a time
function is used. The time function is assigned to words AR 18 to 21 of the
C200H.
S Support tool settings
The following settings are made using the support tool.

S Program operation
When the created screen is displayed on the NT620S/620C and the program is
executed, the operation is as follows.
(1) When bit 00000 comes ON, the date and time (AR 18 to 21) set in the PC are
read, and written to the words (DM0000 to 0003) allocated to numeral
memory tables 264 and 265.
(2) Copy the contents of numeral memory table 264 (day, hour, minute, second)
into numeral memory table 254, which is used for setting the clock function.
(3) After waiting about a second for the memory table copy operation in step (2)
to be completed, copy the contents of numeral memory table 265 (day of the
week, year, month) into numeral memory table 255, which used for setting
the clock function.
The date and time set at the PC will also be set at the NT620S/620C and dis-
played.
232
Clock Function Section 5-6
The method used to notify the date and time is copying between memory tables.
NT620S/620C PC
248 Minute
249 Hour
Procedure 1. Allocate an area in the PC to the numeral memory tables (number corre-
sponding to the data to be read) that are to be made the copy destination.
2. Copy the contents of numeral memory tables 247 to 253 to the numeral
memory tables allocated as the copy destination in step (1).
The copied date and time is notified to the area in the PC.
S Important points concerning numeral memory tables used for the clock func-
tion
Numeral memory tables 247 through 253 store clock data which is updated by
the internal clock of the NT620S/620C. This data cannot be rewritten by the
PC.
Numeral memory tables 247 through 253 are exclusively for display (read
only). Do not attempt to write data to them by using numeral settings or by co-
pying between memory tables.
Do not allocate the numeral memory tables to which the clock function is as-
signed (numbers 247 to 255) to PC words.
This is the procedure for reading the time (hour, minute) set for the
NT620S/620C.

When the program is executed, the operation is as follows.
(1) When bit 00000 comes ON, the contents (“minute”) of numeral memory
table 248, which is used for reading the clock function, are copied to numeral
memory table 258.
(2) After waiting about a second for the memory table copy operation in step (1)
to be completed, copy the contents of numeral memory table 249 (“hour”),
which used for reading the clock function, into numeral memory table 259.
The hour and minute set in the NT620S/620C are stored in DM0000 and
DM0001, which are the words allocated to numeral memory tables 258 and
259.

- If a screen disappears while bit 15 is ON, switch bit 15 OFF and then back ON
again.
S Priority registration for processing (NT link 1:N connections only) (bit 14)
It is possible to register one of the multiple PTs connected by the 1:N NT link
method to have processing priority. The PT for which bit 14 is set ON (1) is
given priority over the other PTs and has a higher response speed for display,

NT620S/620C Status Control Section 5-7
Another way to stop a buzzer sounding is to use a touch switch to which the
buzzer stop attribute function is allocated.
Whether or not the buzzer actually sounds also depends on the setting of the
“buzzer” memory switch of the NT620S/620C. For details on this setting, see
“Using the buzzer” (page 83).
In addition to PT status bit operations, the buzzer status can also be controlled
by using screen attributes. The screen attributes are set with the support tool.
Buzzer attribute: Set whether the screen will sound or not when a screen is
displayed, and, if it sounds, the type of buzzer.
S Display history initialization (bit 11)
“Display history initialization” initializes the display history in the
NT620S/620C.
When bit 11 is switched from “0” (OFF) to “1” (ON), the display history in the
NT620S/620C is initialized.
After initialization, it returns to the “0” (OFF) status.
S Screen printing (bit 7)
Hard copies of the screen can be made by connecting a printer to the
NT620S/620C.
When bit 7 is set from “0” (OFF) to “1” (ON), printing of the screen displayed at
that time starts. Note that it is not possible to stop printing part way through.
Start printing after confirming that bit 7 (printer operating status) of the PT sta-
tus notification area is in the “0” (OFF) status.
When printing starts and bit 7 of the PT status notification area has been set to
the “1” (ON) status, the “screen printing” bit is returned to “0” (OFF).
S Window opening (bit 6)
It is possible to display a partial screen overlying the currently displayed
screen. This partial screen is called a “window”, and control of windows can be
allocated to touch switches. “Window opening” is specified to disable the
opening of windows using touch switches.
When bit 6 is set to “1” (ON), windows will not open even if a window opening
touch switch is pressed, and currently open windows are closed.
S Numeral/character-string input (bit 5)
This bit makes it possible to disable the input and thumb wheel type input of
numerical values and character-strings into numeral/character-string input
fields.
When bit 5 is set to “1” (ON), it will not be possible to input anything into input
fields by pressing touch switches to which numeric keys and character-string
keys are allocated. It will also not be possible to change numerals using thumb
wheel type input.

This bit is set to “1” (ON) when screen printing is executed at a printer con-
nected to the NT620S/620C in accordance with an instruction from a touch
switch (screen print key) or from the PC. On completion of printing the bit is set
back to “0” (OFF). Note that if the NT620S/620C system menu or an error
screen is displayed, the bit will be set to “0” (OFF) even if the printer is printing.
The PT status notify area (PT → PC) can be allocated to the PC memory areas
listed in the following table.
f: OK : NG
Since all the CVM1/CV-series special auxiliary relays are allocated to the sys-
tem, they cannot be used for applications not related to the system.
The range of each memory area differs according to the PC type. See Appen-
dix L “PC Memory Map” (page 327).
Procedure 1. Use the support tool to allocate the PT status notify area (PT → PC) to the PC
memory.
2. Write a PC program to read the “PT status” word of the PT status notify area
and check each bit status.
The information in the PC status notify area (PT → PC) is written to the PC
when the NT620S/620C status is changed during operation.

SECTION 6
Using Memory Link
This section gives an overview of memory link operations and contains explanations centered on communications between
the NT620S/NT620C and host when using the memory link.
243
Operation of the Memory Link Section 6-1
PT Host
6-1-2 PT Memory
The PT memory is a virtual PC area within the NT620S/NT620C. However, there
is no classification of the area as there is with real PC areas: it consists of an I/O
relay area of just 10000 words from 0000 to 9999. Consequently, only I/O relay
words can be designated as allocated words.
Memory link can be treated in exactly the same way as direct connection, except
244
Operation of the Memory Link Section 6-1
that there is no area classification. The specification of bits is also the same.
A diagram of the PT memory is shown below.

Reference - The PT memory is backed up by the battery even while the NT620S/NT620C
power is OFF.
- The explanations in this section concentrate on the memory link
communication method. For details on control and notification between the
NT620S/NT620C display elements and the PT memory, refer to Section 5 “Us-
ing Host Link/NT Link”.
245
Outline of Communications Section 6-2
Notify commands
These commands serve to notify the host of the results of operation at the
NT620S/NT620C. Only these commands are issued by the NT620S/NT620C
and, therefore, there is no response for them.
The following four switches are available.
S Touch switch input notify command Page 259
S Numerical input notify command Page 260
S Character string input notify command Page 261
S PT status notify command Page 262
Re-send command
This command lets the NT620S/NT620C re-send a notify command. It is issued
from the host and the notify command issued last is re-sent from the NT620S/
NT620C.

In the format, parentheses are used to indicate parts that can under some cir-
cumstances be omitted, and ** is used to indicate the ASCII code (two hexadeci-
mal digits) of the specified character.
In the explanations of commands, expressions such as “4 BCD digits” and “2
hexadecimal digits” are used to mean (respectively) “the ASCII character string
for a numerical value expressed as four BCD digits” and “the ASCII character
string for a numerical value expressed as two hexadecimal digits”, etc. Do not
specify BCD and hexadecimal data without alteration: always convert it into an
ASCII character string before transmission.

2. While lightly pressing down on the projection on the upper part of the back-
light connector, pull the connector toward you to remove it from the NT620C
body. While doing this, be careful not to put excessive strain on the backlight
cord.
3. Remove the screws that secure the backlight with a Philips head screwdriv-
er, grip the handle, and pull the backlight out (note that the screws are de-
signed not to come out of the backlight). As shown in the figure below, the
backlight can be removed easily if it is pulled straight out to begin with and
then at a downward angle.
4. Insert the new backlight. Reversing the action in step 3, push the backlight in
at an angle to start with, then, when it contacts something solid, continue by
pushing it in straight. Now make sure that the positions of the screws that
secure the backlight coincide with the positions of the screw holes in the top
of the NT620C PCB.
The backlight has been inserted correctly if it fits snugly in the gap above the
PCB inside the NT620C.
5. After inserting the backlight, secure it well by replacing the screws with a Phil-
ips head screwdriver.
6. Engage the backlight connector with the NT620C connector, ensuring that
the projection on the backlight connector is uppermost. Insert it fully home
and then check that it will not come out if pulled lightly.

7. Fit the CFL case lid and secure it with the screw.
First engage the protrusion at the left end of the lid with the opening in the
NT620C, then close the lid while keeping them engaged. Be careful not to
trap the backlight cord when closing the lid.
8. Switch the power ON and confirm that operation is correct when the tests on
the items indicated below are performed under I/O CHECK in the mainte-
nance mode. Also carry out a test to check communication with the host.

Operation 1. Keep the power ON for at least 1 minute and then turn it OFF.
Note Unless the power is kept ON for at least 1 minute, the memory contents cannot
be retained for more than 5 minutes without a battery.
2. Turn off the power to the NT620S/620C and remove the lid of the CFL case,
located at the upper right part of the rear of the NT620S/620C: remove the
screw with a Philips head screwdriver, then open the CFL case lid.
276
Maintenance of the NT620S/620C Section 7-3
5. Close the CFL case lid and secure it with the screw.
The battery may be replaced while the power is ON. In this case, there are no
restrictions on battery replacement time.
Caution Never short the “+” and “–” terminals of the battery. Do not recharge, take apart,
or heat the battery, or discard it into open flame. Attempting any of these will lead
to hazards such as fire, leakage of electrolyte, rupture, etc.
When replacing a battery, ensure that the battery terminal does not touch the
board in the NT620S/620C.

Caution When installing the PT in the operation panel, observe the following points.
S Do not install the unit in locations directly exposed to chemicals or steam, or locations where
there is excessive dust.
S Do not install the unit at locations where the ambient temperature goes outside the range 0
to 45_C in the case of the NT620S and 0 to 40_C in the case of the NT620C, or where the
relative humidity goes outside the range 35 to 85% RH.
If the ambient temperature exceeds the range indicated above, install a fan or an air condi-
tioner.
S Do not install the unit directly above equipment that generates a lot of heat (heaters, trans-
formers, large capacity resistors, etc.)
Caution S Take the following points into account in order to prevent noise.
(1) Avoid installing the unit in panels in which high-voltage equipment is also installed.
(2) Install the unit at a distance of at least 200 mm from power lines.
(3) If the unit is installed next to equipment that generates a strong electric or magnetic field
(solenoids, etc.), provide a gap of at least 40 mm.
S Provide sufficient space for ventilation
S Do not install the unit in locations where it will be subject to strong vibration or severe shock.
S To ensure that the unit can be operated and maintained without difficulty, install it at a dis-
tance from high-voltage equipment and power equipment.
Note - The view angle of the LCD of NT620C screen is 30_ to the left and 30_ to the right. Install it at a position
and height where operators will be able to see it well.
- Install the unit as far as possible from personal computers, amateur radio equipment, radios, etc. The
radio waves generated by the unit may cause interference that will affect these types of equipment.

Appendix F
NT620S/NT620C Internal Processing
The following processing is executed inside the NT620S/620C. Processing is divided into two types: periodic pro-
cessing and incidental processing.
Periodic Processing
The following processing is executed inside the NT620S/620C to enable high-speed control from the PC.
Usually, the only data read from the PC are the elements used for the currently displayed screen. Even if the con-
tents of the PC words allocated to memory tables are changed, these contents are not updated at the PT unless
the memory table is used for the displayed screen. However, the bit memory tables that can be used with Ver.3 and
later versions of the direct connection function can be set to be read continually.
Initial values written to the memory tables When the values registered in the NT620S/620C are
(PT→PC)
used as the initial values in the memory tables, these
values are written into the allocated words of the PC.
Screen switching
Screen element registration (PT→PC) In order to enable fast batch processing, the elements
used in the displayed screen are registered in the PC
in advance. Approximately 120 words can be
registered per screen.
Reading of registered elements (PT←PC) The statuses of the registered elements are read from
the PC and the display is changed.
Reading of of the elements that could not be The status of the elements that were in excess of the
registered (PT←PC)
number that can be registered and could therefore not be
registered is read from the PC, and the display is
changed. This processing is continued until the statuses
Reading of of the elements that could not be of all the remaining elements has been read.
(PT←PC)
registered
Reading of the PT status control area (PT←PC) If the number of elements that could not be registered is
large, the PT status control area is read after every two
element readings.
Reading of of the elements that could not be
(PT←PC)
registered
297
NT620S/NT620C Internal Processing Appendix F
298
NT620S/NT620C Internal Processing Appendix F
Incidental Processing
When the status of the NT620S/620C changes during operation (ex. touch switch is pressed), the processing for
writing the changed data to the relevant area of the PC memory is executed.
This kind of processing is only executed when statuses change. When changes occur simultaneously, the proces-
sing is executed in accordance with the order of priority.
Writing to numeral memory tables Changing the contents of words allocated to the PC
(PT→PC)
when the value in a numeral memory table has
changed.
Changing the contents of words allocated to the PC
Low Writing to character string memory tables (PT→PC) when the value in a numeral memory table has
changed.
Data is only written to PC bits and numeral/character string memory tables for elements in screens currently being
displayed. If the contents of numeral/character string memory tables that are not being displayed change, the
changed contents are not written to the PC.

S Wiring connections
CVM1/CV-series host link units have two types of connector, which must be wired differently.
The NT620S/620C does not use pin 4 (RS) or pin 5 (CS). Either short the RS and CS pins of the PC connector
together or set the CTS setting selector switch at the rear face of the host link unit to “0V” (see < in the figure).
Connect the cable shielding wire to the connector cover and pin 1 at the host link unit end of the cable only.
