According to you what are the reason, why then AFValue.IsGood property (datareference tablelookup) return false, while yet the AFValue.GetValue is != null ?Thank for helping.
IsGood is a indicator of the data "quality", not whether the data exists or not. If you have a PI Point with numeric point type, then if the event is from the system digital state (No Data, Comm. Fail, etc), then the IsGood property is false. So in this case, if the point type is numeric, I would expect AFValue.Value to be an AFEnumerationValue.
