Using alarm delay

The Alarm Delay property enables you to configure digital, analog, and advanced alarms so that they do not activate unless their triggering conditions remain true for a specified period.

For analog alarms, this means the analog variable need to fall within a specified range for the duration of the alarm delay period before an alarm will activate. In the case of digital and advanced alarms, the triggering condition of the digital variable or Cicode expression need to remain true for the delay period.

An example of where alarm delay could be useful is in monitoring temperature. By setting a delay period, you can filter out momentary alarms caused by the temperature moving in and out of different ranges.
