I am trying to detect error(Not connect, No data, Error and Scan Off) and flat lines(constant value) for a tag/trend in a duration of 5 hours in PI processbook. I am trying to code it in VB. I am able to detect it for current values but not during the last 5 hours. What would be the best way to detect all these errors.
