Hi all,
I have an issue with S7-1512C cpu. Cpu has error Error on partner - Wrong partner port. Project has 1cpu, 1hmi and some tcp connection. Profinet tpology is not defined. DO you have some tips please?
Are you sure there is nothing in Topology View. Only seen this error when something was defined in Topology View, ended up having to add a dummy Ethernet Switch.
Unless it is a big project, maybe backup the project and then create the correct topology. I guess you would use unmanaged Siemens Switches to simulate the non-Siemens stuff. Sorry I can not be much help, not a lot of experience with this stuff.
