Hello Experts , I'm using 5 CPU416-3 PN/DP in a Multi-project (Step 7 V5.6+HF1) with WinCC 7.4+SP1+Upd4. I have made S7 Connection with all the PLC and HMI OS Server in NetPro to generate the Tags in "Named Connection" but unfortunately I can't establish the connection between HMI Server and 2 PLCs using "Named Connection", the rest 3 PLCs are communicating although. The 2 PLCs which are not communicating are in "Run" mode and I can read/write the Tags using TCP/IP Protocol in WinCC but Named Connection is not working. I have deleted and rebuilt the Connection many times, downloaded the Entire NetPro in Both the PLCs and also in HMI Server, Compiled all the Tags (also with memory reset) and downloaded the HMI Project but no improvements, I'm always getting the same error. Can you please help? The screenshot from the NetPro Properties and the "S7 Connection Diagnostic" in HMI Server is attached for your reference. Thank you in advance!
