Hello all again:


I have got manual data entry in a custom symbol developed by Anna Perry in PI Vision. I am using an analysis to get the last value entry but it looks like it is not working properly because the result is not as expected.


I use PrevVal as PrevVal('tagname','*'). Evaluation every 10 minutes

I use PrevEvent as TagVal('tagname',PrevEvent('tagname','*') Evaluation every 10 minutes with offset: 09 minutes
