    Archive Value using Next (or next only), giving bogus results (PI Datalink)

    Gates

      Hello all,

       

      i'm fairly new using PI Datalink, but i'd like to know if the result i'm getting is "normal" & hopefully, someone as experienced this before...

       

      On a specific query, i'm asking for Compressed Data on a specific Tag. This is the result

      When i make another query (archive this time), i ask for Next (or next only) using the TimeStamp 19:17:01. The result should be 20:54:50, but nope, it still outputs to 19:17:01.

       

      I have a bunch of line doing so & it works perhaps at 95% of the time...for a few lines though, it seems as though it won't fetch the correct value.

       

      Any tips?

       

      Thank you
