    How to retrieve array of historical process data from PI ACE?

    konspe

      Hello All,

      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?

      Thank you!

       

      Best,
      Konstantinos
