Hi all,

Thanks in advance

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.
 
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 !
