Historian: SQL evacuation fails with certain archive files

Description

An error occurs in the Historian during the SQL evacuation of archive data. The evacuation fails for certain archive files. This occurs when the last value of a variable is "NaN". In this case, this value is expected to be skipped and reported. However, this does not work if it is the last value.

This error has been fixed. Archive files containing "NaN" entries are successfully evacuated. Invalid lines are skipped and all data - except the "NaN" entries - is sent to the database.

To benefit from this fix:

  • Update your zenon Software Platform to the latest build of zenon 11 or higher.
