I have created a Trend screen in RSFactoryTalk to display some temperatures. With the screen displayed, I can see the trace and history building up. If I navigate away from the screen and come back, the previous info. has disappeared and I'm staring at none of the historic data. The new values appear as if it's the first time the screen is displayed.
How can I retain these values such that when I return to the Trend screen the history is still there?
Also, I would like to be able to save this information in a csv file (or similar) on a rolling 7 day basis for future access by excel or similar.
All hints and help appreciated! Many thanks.
