High Low Alarm Deadband in Absolute Value. A deadband is used to minimize nuisance alarms or repeating alarms caused by an oscillation near the Alarm Limit. The deadband comes into effect only after the alarm limit is violated. The deadband specifies the change in the tag's value required to be considered a return to normal or not in alarm. The deadband can be in either engineering units (absolute value) or percentage of span. This field is for ANALOG tags and parameters only.
