This problem started today. I have a transaction group that is suppose to run every minute.
It has 3 items:
Line#Counter = OPC to counter in PLC
Line#Previous = Run always script
ORDER BY linerates_ndx DESC LIMIT 1
Line#Count = Triggered Expression
For some reason every other cycle it is not updating the previous count and the difference for one minute is actually 2 minutes.
Any ideas as to where to troubleshoot this?
