Hello Ben; In Modbus/TCP a client polls one or more servers. So if you want to read and write to various CPUs they must be servers and your CPU must ne a client on Modbus/TCP. The MB_Client and related Modbus/TCP instructions are explained in this manual: STEP 7 Basic V12.0 And you will find a sample program from our friend Pegaia in this thread: Tips and sample program for MODBUS TCP Hope this helps,, Daniel Chartier |
