Hello,

I have same problem. I have 1212C CPU, with one port. I need read data from inverter by modbus TCP/IP, recalculate in program and send data to scada by TCP/IP. I use MB_server with local port 502 and I don't know that port I need for client? Or maybe it not possible? If I use same port for client and server, but not in the same time (disconnecting blocks) program working. But in this situation scada lost connection and we have alarms.

Split from MB_Client and MB_Server in same project.
