Good day, I have successfully used the "ChangeConnection" function of WinCC Flexible before, to change an MP377 HMI's target PLC IP address when connected to an S7-300 PLC.

ie. If the S7 PLC IP address changes, I can change the IP address that the MP377 looks for from the screen to re-establish a connection.

However, the "ChangeConnection" function does not work with non-Siemens PLCs. Is there a known method to change the MP377's target PLC IP Address for non-Siemens PLCs? I am using a SCADAPack with the Modbus TCP/IP driver from WinCC Flexible. Everything works great, and I have communication etc. I just want to be able to add the ability for the MP377 to be able to change the target PLC IP Address, in case the IP address of the SCADAPack changes.

Any input would be greatly appreciated.
