I am stuck at a WinCC Unified Collaboration problem. PC A hosts the runtime for the WinCC Unified interface. I can open the user interface on PC in the browser. On PC B I am trying to access the interface from PC A via the Unified collaboration data. I know that I have to export the collaboration data in TIA Portal on PC A and import them in PC B. However, In the WinCC Unified interface on PC B the UI from the runtime on PC A is not displayed.

I think this has something to do with Certificates and such things, but I am completely lost on how to configure this. In addation, the official Siemens TIA Portal documentation is completely useless again, because there is NOTHING documentated at all about this topic.

Does someone know how to solve this? Or does someone has any helpful guide or PDF where this is explained? Why is everything in TIA Portal so horribly undocumented? How am I supposed to know how one has to set this up without any help document?

Hello,

I believe there is the detail documentation available on how to configure Collaboration devices in the TIA Portal documentation.

You can go through below section in documentation:
