Hi
We would like to validate data comming into PI beyond the quality stamps it gets from the OPC interface.
Lets say we have a tag which a range of 0 to 100 and we want to check if the values suddenly has erratic behavior like jumping from 10 to 90 in a timespan not possible in the real world. When that happes I want to be able to mark the value as "bad" or questionable.
I realise I can check this from ace or Abacus, but can I also write to the point marking it bad?
