Communication between a CommandHMI and Omron Sysmac C/CPM/CS/CJ series PLCs

 

The device driver is used for CommandHMI to read and write the data or state of SYSMAC C/CPM/CS/CJ series PLC register.
The serial communication connection is established through the serial port on the HMI and the serial port of PLC.

Wirring from the HMI to the RS232

HMI
COM1 or COM2
PLC
2 RX <> 2 TX
3 TX <> 3 RX
5 GND <> 9 GND
4 <> 5 CTS/RTS

The distance HMI<>PLC must be less than 10 m

HMI-Tool configuration

Choose RS232
