Group Settings

Filters Tab

If the Perform by Server option is checked, any filter configured in this tab is put into the WHERE clause of the query sent to the database to retrieve data for the group. Otherwise, the configured filtering is performed by the reporting engine after the values are returned. It is recommended to leave this setting checked as the performance is much better.

The Alarm Type defines how the alarms are returned from the Proficy Historian.

  • Alarms returns an entire alarm life cycle as a single record.

  • Alarm History returns separate records for every alarm transition.

  • Events returns the simple and tracking events.

For more information, see ihAlarms in the Proficy Historian documentation.
