Please guide me if anybody have tried earlier. Thanks & Regards, Mohsin B ------------------------------------------------------------------------------------------ Split from Modbus TCP communication - using one S7-1500 as a slave, and a central PC as master.

You will need to setup 2 separate TCP connections on the Simatic: 1 to act as client and 1 to act as server. You then use 2 instances of the TCP communication blocks.
