We have a scheduler in VB.NET using AF SDK v4.0.30319. The objective is to fetch from PI Server the snapshot value and the associated timestamp of a tag. Used the following functions to fetch them.
myPIvalue = myPoint.CurrentValue.Value
myPItime = myPoint.CurrentValue.Timestamp
My code captures the current value and time stamp and stores in SQL DB table, but it does not match with PI-SMT values of same period, the value matches but not the timestamp.
But the associated time stamp for current value as seen in PI-SMT is wrong, it some times less than 3 or 4 hours or 1 hour etc.
Is the AF SDK function of currentvalue not correct?
