Prepare Variables for Historian Integration

To allow variables to be automatically configured in Historian, you initially need to identify the variables you would like included in this process within Plant SCADA. This involves adjusting the Historize property for each required variable to "true".

The following variable types are supported:

• Variable tags

• Trend tags

• Digital alarms

• Time-stamped alarms

• Analog alarms

• Advanced alarms

• Multi-digital alarms

• Time-stamped digital alarms

• Time-stamped analog alarms

For each variable you would like to be automatically configured in Historian, you need to set the Historize field to "true".

Note: If a variable has the Historian field set to "false", it will still be added to the Historian data sources directory when an import schema is run. You will still be able to manually historize and publish the variable within the Historian environment.
