Hello, I am trying to set loging data as property for Trend. In wincc runtime professional its was not problem, basic function. 

I was searching and not found any example how to add logging data as property in faceplate... and make trend without faceplate its very impractical for future editing.  

Its some way with standard option or with using scripting to set logging data as property ? Thank you very much for answer and help. 

I finally solved it using this manual... I found this manual via AI-powered help in TIA V20:

Example: Configuring a Trend Control with Logging Tags in a Faceplate Type (RT Unified). I am happy now. :)

Did you also find how to get the TrendCompanion window to popup in the faceplate (or regular HMI screens for that matter) as soon as you would click on the Calculate statistics button in the TrendControl window.
