1. Overview
1.1 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.
◆With two PLC programming ports. CX3G PLC has one MiniB USB port with faster
downloading speed; one Rs232 programming port with 8 mouse hole
sockets.FX3GC PLC has one MiniB USB port with faster downloading speed; one
Rs422 programming port with 8 mouse hole sockets.
◆Support Mitsubishi programming port protocol/Modbus protocol/Rs protocol/BD
board protocol, PLC communication with each other and other devices is easily
achieved.
CX3G-16M/24M/32M/48M PLC is with 2 com ports. Default is with 2 RS485, or
customized as 1 RS485+1 RS232, or 1RS485+ 1 CAN port, or 1RS232 + 1 CAN port.
CX3G-34M/64M/80M PLC is with 3 com ports. Default is with 2 RS485,or customized
as 1 RS485+1 RS232,CAN port is optional for connecting HMI,VFD and other
equipment.
For FX3GC-30M, 1 Rs485 can be added;
For FX3GC-16M, com ports/ analog can be added, at most 2 Rs485+1 CAN
port+6AD4DA can be added; or 1 Rs485+1 CAN port+8AD4DA can be added; or 1
RS485 +8AD6DA can be added, or 2 RS485 +1 CAN port can be added.
◆High speed counter. For CX3G PLC,regularly single phase 4 channels 60KHz、2
channels

10KHz or double phase 2 -3channels up to 60KHz, and could be customized as single
phase 100khz or 2 channels double phase 60khz+ 1 channel 10khz; For FX3GC PLC,
regularly single phase 1 channels 100KHz、4 channels 20KHz or double phase 1
channels 60KHz、2 channels 10KHz
◆High speed pulse, regular as 8 channels Y0-Y3 in 100KHz,Y4-Y7 in 10KHz, could
be customized as 8 channels 10-100KHz;
Note: High speed counter+High speed pulse should be less 480KHz.
◆Support multiple types analog individually or mixed ones for analog output and
input.
Precision of AD/DA is 12bit.Temperature/current/voltage for input. current/voltage for
output.
For CX3G PLC, at most 16DI/8DO. For FX3GC-16M, com ports/ analog can be added,
at most 2 Rs485+1 CAN port+6AD/4DA can be added; or 1 Rs485+1 CAN
port+8AD/4DA can be added; or 1 RS485+8AD/6DA can be added or 2 RS485+ 1
CAN port can be added.
◆Up to 40DI/40DO for CX3G PLC, up to 16DI/16DO for FX3GC PLC.
Relay/transistor or mixed relay and transistor for output.
◆Convenient for wiring. CX3G adopts 5.00mm pluggable terminals. FX3GC adopts
3.5mm pluggable terminals.
◆Easy installation. DIN-Rail (35mm width) installation and fixed hole installation.
◆Flexible, can be customized accordingly.
