Communication between INTOUCH and ABB ACS550

Chandler Chen

I got a ABB ACS550 connected to a COM port in order to control motor revolving speed with Intouch via MODBUS RTU. Values can be read. When i start the motor, the Log Viewer tells these "failed to verify Modbus RTU frame" and "PLC poll message timed out on port xxx" frequently. I would appreciate any help.

Thanks then.
