An Alarm to Normal Delay Time can be specified. It is 0 by default. It specifies the time in Milliseconds for a tag to be in a Normal Condition after an Alarm Condition, before an alarm state is self-acknowledged (returns to normal) without operator intervention. This occurs only if Ack Alarm by Return to Normal is enabled in SCADA Node properties. The maximum value for analog alarm delay time (DELAYA) is a 6,000,000 milliseconds.
