Hello, If I make some change on Archive editor ( PI SMT), I cannot get an error message if an interface is sending data to a PI Tag through buffering ( real -time data) as PI SMT has the full power, right? Thank you
If you are running PI SMT on a Windows client that has buffering enabled to the PI Data Archive, then changes issued in the Archive editor are not sent directly to the data archive. Rather they are sent to client's buffering service, at which point SMT no longer has any control over the values. It is the responsibility of the buffering service to send the data to the data archive. That could be a split second later, or it could be many seconds or minutes.
If there could be an error, it is not triggered by SMT but rather by the buffering service. There is a one noteworthy exception: if the tag is buffered AND you are trying to edit the snapshot, you will get an error returned to SMT.
