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
