Historian: At reload an old value is written again / received values with old external timestamp not discarded

Historian: At reload an old value is written again / received values with old external timestamp not discarded

Description

In the Service Engine, data from already closed archives is written to the current, open archive capsule in the Historian.

This problem can occur:

  • By project reload.
  • If the PLC sends variable values with an external timestamp from the past. These values with a possibly very distant timestamp are saved in the current ARX file.


This problem has been fixed. Values that have already been archived and values with an external time stamp from a long time ago are no longer entered in the current ARX file.

To benefit from this fix:

  • Update your zenon Software Platform to the latest build of zenon 12 or higher.
