Software Compatible with GX WORKS 2


◆ Powerful, compatible with FX3G/FX3U/FX3S PLC, high processing speed.(supports Ladder diagram and SFC language, does not support structured programming/labels).

◆ Upper computer programming software compatible with GX 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.

◆ High speed counter, regular as single phase 6 channels 60KHz or AB(Z) phase 2 channels 60KHz+ AB phase 1 channel 10KHz.

◆ High speed pulse, regular as 8 channels Y0-Y3 in 100KHz,Y4-Y7 in 10KHz. 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.

◆ Up to 40DI/40DO. Relay/transistor or mixed relay and transistor for output.

◆ Convenient for wiring. CX3G adopts 5.00mm pluggable terminals.

◆ Easy installation. DIN-Rail (35mm width) installation and fixed hole installation.

◆ Flexible, can be customized accordingly.
