I am new to vCampus.
I want to program a calculation in PI ACE using VB.NET. Specifically, I would like to retrieve an array of historical (archived)numerical process data and their corresponding timestamps, store them in two arrays and then perform some calculations with the data.
I have not found this information in PI ACE manual.
I only saw functions to retrieve a single value and a single timestamp.
Could anyone point me to some information about how
to retrieve an array of historical data?
