The Alarm Delay property enables you to configure digital, analog, and advanced alarmTriggered when the result of a Cicode expression changes to true. Use advanced alarms only when alarm functionality cannot be obtained with the other alarm types. If you configure too many advanced alarms, your system performance can be affected.s 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 expressionA statement (or group of statements) that returns a value. An expression can be a single variable, a mathematical formula, or a function. 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.
