how to create a simple PI PE counter

Hi all,

This should be really easy, but I am having a hard time with it. I need to create a Performance Equation to count while a tag has a value = "whatever", then reset to 0 when it doesn't. I have (as a test)


if 'ba:phase.1' = "Phase 1" then '' +1 else '' = 0


where is the name of the tag I created for this.

All I get when I run this is 0,1,0,1,0,1 every minute (I set it to scan class 1 so I could get a minute counter).

I tried to run it with

if tagval('ba:phase.1','*')

but that didn't return any different results.


Any help would be gratefully appreciated.
