Stale data and return-to-normal processing

When the data quality of a monitored point is declared old by the Age Watchdog application, the state of the ageWatchdog point changes to "Stale Data". The Age Watchdog application continues to watch monitored points in this state by checking the timestamp once every minute. If the timestamp of the telemetered point monitored by the ageWatchdog record changes, the ageWatchdog point requires Return-To-Normal processing because the monitored point is considered fresh again.

When the timestamp on a monitored point with a "Stale Data" status changes, the following Return-To-Normal processing occurs for the ageWatchdog point:

• The state is set to "Fresh Data".

• An ageWatchdog related, non-persistent alarm is issued against the point's remote if it is not normal-alarm-inhibited.

• An ageWatchdog related event is issued against the point's remote if it is not normal-logging-inhibited.

• An ageWatchdog related event is issued against the point if it is not normal-logging-inhibited.
