in my opinion the PN/PN coupler should work. It is important that you do not insert the ProfiSafe mappings in the configuration. They are not supported. It is best to test the communication with a simple mapping (e.g. 16Byte In and 16ByteOut). This must be entered on both Profinet masters.
The issue has be solved, it issue was that the pn coupler, won’t setup the ip from automation studio remote. So instead I use the proneta software from siemens. And then i also can see more information on the coupler as well.
