Recovery Mode (Calculation Collector)

Recovery logic is activated when the Calculation Collector and Historian Server reestablish connection after a connection loss. Recovery mode allows the collector to recover data when the connection between the collector and the server is reestablished. Recovery mode produces calculated values for time when the Calculation Collector was not running.

When using recovery mode, all referenced tags in an unsolicited calculation must be listed as trigger tags. For more information, refer to About Recovery Mode.
