    PrevEvent or PrevVal with manual data entry

    Ervin Tovalino Espinoza

      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
