S7-1500 Wrong partner port

putiss · Jul 10, 2019

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?

Thanks in advance

Did you define that the HMI would be connected on that port or the other one?

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.

Topology view is without connections. Switches are non siemens - could it be this problem?

Create a new project and upload from the CPU, and check if there is a topology.

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.

Yes I use some siemens switch to check it...

here is a topology from upload

If you right click the PLC in Topology View and then choose Port Interconnection, is anything shown in the Partner port?

Solved!
I defined profinet topology between plc and hmi to P2 port of cpu and added new direct cable between cpu and hmi.

Thank you all !
