@IHolzinger- did you find an answer for this. I experiencing same issue

 Hello all, 

I am facing the same issue. My tag logs are not showing in trend control. Any idea what could be the reason. I am using unified pc

• MTP1500 Unified Comfort
• Panel simulated on Windows 10 machine

On my side, the error was due to an invalid storage directory in WinCC Unified Configuration for the archive databases. To check your storage directory settings:

1. Open the windows application 'WinCC Unified Configuration'.
2. Navigate to 'Archive Settings'
3. Specify the folder where the tags should be stored. For me, this was set to 'S:\UnfiedArchive' by default. I had to change this to a valid directory (e.g. 'C:\Users\..')
4. Accept and apply settings.
5. You'll have to restart your PC for the settings to take effect.

Hope this will save you all some headaches.

BR,
Wilhelm.
