Run-time Logging Criteria

The Process Log Manager logs tag values to the history database. Logging occurs only when a batch is active for the associated unit or connection. The name of the unit or connection can be found in the first field of the tagname. Batch information is obtained from Information Manager (InfoMngr) application at run time and recorded with the tag value in history.

For example, the ReactorA-Heat-Temp-ACT tag is logged only if there is a batch active in the ReactorA unit.

If a batch is not active within the unit or connection, the value is not logged.
