1. Overview
COOLMAY CX3G PLC has the following advantages：
◆Powerful，compatible with FX3G/FX3U/FX3S PLC, high processing speed.
◆Upper computer programming software compatible with Works 2/GX Developer8.86
◆Military level 32 bit CPU adopted, which is faster and more adapted to industrial
environment of high electromagnetic interference.
◆Special encryption, prevent illegal reading thoroughly. 8-bit encryption, 12345678 as password
can thoroughly prevent reading of ladder logic program.
◆Clock supported, rechargeable battery adopted.
◆Round Rs232 for programming, Mini B-type USB programming port also adoptable.
◆2 Rs485 or 1 Rs232 and 1 Rs485 can be added, canbus optional for connecting HMI、VFD
and other equipment.
◆Support Mitsubishi programming port protocol/Modbus protocol/Rs protocol/BD board
protocol, PLC communication with each other and other devices is easily achieved.
◆At most 8 100KHz high speed pulse. Among which, regularly Y0~Y3 is 100KHz, Y4~Y7 8KHz
(100KHz can be customized).
◆At most 6 60KHz single high speed counter or 2-3 AB(Z). At most 60KHz for double frequency,
24KHz for quadruplicated frequency.
◆Support multiple types analog individually or mixed ones for analog output and input. At
most 20DI/8DO, the precision is 12 bit. Temperature/current/voltage for input. current/voltage for
output.
◆At most 40DI/40DO, relay、transistor or both relay and transistor for output
◆Convenient for wiring. 5.00 pluggable terminals adopted for convenient wiring.
◆Easy installation. DIN-Rail (35mm width) installation and fixed hole installation.

Current Type1 0~20mA 0~4000 5uA 1%
Current Type2 4~20mA 0~4000 4uA 1%

The transmitter which is integrated inside PLC is one of the above table or mixed ones, it is up to
customers.

5.1.2 Analog input reading

5.1.3 Analog input sampling

R23600~R23611 is filtering cycles, defaulted as 0; filtering cycles=( R23600~R23611)* PLC scanning
time, if R23600=1, sample one time each scan circle and change the 1st analog value for one time. The
larger R23600~R23611 value is, the result is more stable. D8073 is smoothing filter coefficients of all analog
input, range: 0~999.

7. Application of high speed pulse

Coolmay CX3G default has 8 channels high speed pulse, Y0-Y3 normally each 100KHz, Y4-Y7 normally
8khz (100KHz can be customized), variable speed supported, the initial/final speed of start/stop is 0,
diagram as below: (take accelerate and decelerate time D8148 as an example). The total of 8 pulses cannot
be 240KHz.

Accelerate and decelerate time: ( target speed-current speed)* accelerate and decelerate time/highest
speed
Such as: target speed=50000, current speed=20000, acceleration time 100(ms), highest speed=100000,
T=30ms.

CX3G: 8 pulse, the latter 4 accelerate and decelerate=D8148, highest speed are all D8146L.
PLSY、PLSR、ZRN、PLSV、DRVI、DRVA、DVIT、DSZR，only Y0-Y3 support DVIT、DSZR.

8. Coolmay CX3G PLC Communication User Manual

CX3G PLC defaulted has a RS232 programming port, and two communication ports ( Rs232 or Rs485)

can be added. Meanwhile, CANbus is also optional.

★ Serial port1： RS232( PLC programming port)--- support Mitsubishi programming port protocol
★ Serial port 2：RS485/RS232--- support Mitsubishi BD board protocol， Rs protocol and MODBUS
protocol (Modbus RTU protocol communication parameters is set in D8120, station number set in D8121,
can be used as host and slave); The difference between Mitsubishi protocol 1 and 4 is end mark 0A 0D( in
D8124 8125), when Modbus D8120=HExxx, Modbus and former Mitsubishi function can start mark: M8125，
M8125=0: Mitsubishi BD protocol function; M8125=1: Modbus. Support RS、WR3A 、RD3A 、ADPRW.
Can also be set in parameter zone, corresponded serial port is 2. Parameter zone is only valid to this

channel setting. Set serial port 3 is void.

PLC as host, support the below functions of Modbus:

0X03： read hold register, get current binary value in one or multiple registers, range:1-32 registers

0X06: put specific binary value into a hold register( write register), range: 1

0X10: Preset multiple registers, put specific binary value into a sequence of hold register( write multiple

register), range: 1-32

Example of read slave data: RD3A D300 D400 D500

RD3A originally is a read instruction of analog module, the original instruction cannot be used. RD3A

correspond to 03# function, read register (4X). D300 stand for station number of the slave device which has

been read, range 1-247; D400 stand for the address number 0000 (Hexadecimal number) in slave devices of

data which has been read. Value in D500 stand for quantity of register which have been read, range 1-32,

the data has been read is stored in D500+1 successively.

Example of read data to slave: WR3A D300 D400 D500

WR3A originally is analog module write instruction, the original instruction cannot be used. WR3A

corresponds to 16 function of MODBUS, write data to each register(4x) of slave devices. If write only one

register, WR3A correspond to 6# function of Modbus, write one data to one register (4X) of slave device.

D300 stand for station of slave device which has been write, range 1-247; D400 stand for the initial address

number 0000 (Hexadecimal number) in slave devices of data which has been read. Value in D500 stand for

quantity of register which have been write, range 1-32.

★ Serial port3: RS485—support Mitsubishi programming port protocol, Rs protocol and Modbus

protocol ( communication parameters of Modbus RTU is set in D8400、station number is set in D8401， can

be used in master or slave, the same with Mitsubishi CH1).

◆ CAN—CAN adopts transparent data process, communication parameters is set in D8420, station

number set in D8421, the same with Mitsubishi CH2.

The 0th ~9th inn D8420 is CAN baud rate, 1K~1023K. Default 500.
Current support baud rate: 5 10 15 20 25 40 50 62 80 100 125 200 250 400 500 666 800 1000。

Support RS2
RS2 finial parameter=1: serial port 3;
=2：CAN。

When RS2 support CAN, multiple channels can communicate with each other, ID(read 29 bit )=D8442；ID
（write 29 bit）=D8440,at most 8 length.
LD M8000 RS2 D600 K8 D800 K8 K2
LD M8002 MOV H10 D8421
LDI M8422 ANI M8424 SET M8422
Support WR3A、RD3A，such as above data format，D499=0：serial port 2；
D499=1：serial port 3；
D499=2：CAN。
ADPRW： D8126=0(power on default) corresponds to optional serial port 2；
D8126=1 corresponds to optional serial port 1；
D8126=2 corresponds to CAN port
Such as CAN port programming of extended board:
LD M8002 MOV H1 D8421：CAN port of this PLC is main station
LD M8000 MOV K2 D8126
LD M8 ADPRW H1 H2 H2000 K16 M100
Means communication through CAN of this PLC with CAN of slave PLC, read S0~S15 of slave PLC to
M100~M115 of master PLC.
Defaulted state is compatible with the original program of Mitsubishi. Each Mitsubishi PLC can support
ADPRW for only one port, D8401、D8421 decide，D8401 priority. All three ports of Coolmay PLC support
ADPRW.
When M8192=1, the optional serial port 3 support the above protocol
When M8192=0 (power on default), the optional serial port 3 is programming port, namely
programming port protocol .

Zone bit special:

M8192（hold during power off supported）。PLC factory default M8192=0；
M8192（hold during power off supported）。PLC factory default M8192=0；

M8192=0，serial port 3 CH1 is programming port protocol；M8192=1，serial port 3CH1 is stated as above.
