I have a problem when use a PLC CPM2A OMRON (as master) to control many Frequency Inverter Schneider (as slaves)?
I can send command to control FI as RUN, STOP, Frequency... and read status as Current in motor, status of FI... but sometimes the status signal respond to PLC from FI not accurate (noised).

Can anybody help me? Give me a program Syswin 3.4 or CX 4.0 to communicate to FI Schneider via Modbus.

Thanks much!
