Communication PLC Modicon M221 to Kepware

3 posts in this topic

I am using PLC Modicon M221, I want to make communication between PLC Modicon M221 to OPC Kepware by modbus tcp/ip ethernet. In PLC, I use software somachine basic, I set digital input and digital output. And in OPC Kepware my address  00001, but when I switch turn On/Off in PLC, value in OPC Kepware doesnt change. Could you please correct me? Thank you   Bujang
