Hello RIAN Che; The information you are quoting are for the MB_SERVER instruction, which allows for non-redundant connections.If yu have 2 different clients addressing the S7-1500, you need 2 distinct DBs and 2 port numbers, one for each client. If you have a redundant client, you need to think about using a redundant Modbus TCP server, MB_RED_SERVER. Unfortunately, this requires a license... - Where can you find information about the redundant Modbus/TCP instructions for the S7-1200 CPUs and S7-1500 (R/H) CPUs? https://support.industry.siemens.com/cs/ww/en/view/109771501 Hope ths helps, Daniel Chartier |
