Here is my scenario. I am trying to find the best and easiest solution. Currently we do not have any ACE calculations in our environment.

tagA - Digital ON/OFF

tagB - Process flow

so my current PE is: IF STATENO(tagA) = 1 THEN NOOUTPUT() ELSE TAGVAL(tagB)

I am basically trying to filter out a zero/span operation of an instrument. I have noticed that even though tagA = 0 that tagB still hasn't 'levelled' off to its normal operating range. Lets says it takes ~30 mins for the zero/span operation to complete and see tagB return to normal, but tagA only shows it is running the zero/span function for 20 minutes. What I would like to do is once tagA = 1 then do NoOutput() for 30 minutes. Is that possible with PE or am I getting into the ACE world with that?

If it is possible, what kind of code am I looking at for a PE?

Hello Randy,

What you like to achieve is possible with PE. Simply set your PE tag up for natural scheduling with tagA as source. This means that each time there's snapshot change for tagA a calculation will be performed.
