Hello

I want to draw a trend from the datas that i read from a csv or text file. (not a real time trend, the data is read from an ODK aplication in advance). How can i realise this? If I use a normal trend, and define a tag for data source that would not possible. If i define a log as data source, then i should be able to log data into this log via a script. In WinCC Advanced this was quite easy. But I cannot see a function for that in WinCC Unified. How should I proceed?

Split from WinCC Unified – Simple Sample - bit triggered Trends.

Thank you so much, last question:

Should i prefer normal trend or function trend?
