Hi all,
I'm using the M172PDG18R.
If I using a Modbus RTU client, I can see from the M172 side that the client is correctly communicating by using the 'sysMODBUS_msg_received_RS485_1' parameter.
Is there a similar feature, or another method I can use for observing the Modbus TCP interface when the M172 is a server?
Thanks.

HI,
I don't think we have this same Modbus status variable in TCP.
However, as a:
- Client you can use the System Varaible "sysMbMTcpNodeStatus" to have information on the Modbus TCP communictaion Status.
- Server you have the Variables "sysMbSTcp_SocketServerInfo"
