What is the better way to mask an intermittent alarm where the parameter value changes?

Hello

Have an intermittent alarm from a device fan that I would like to mask.

The problem is that the text that comes in the "parameter description" of the alarm has on it a value that changes (an example: "Fan Alarm critical - RPM 15000, 16000 threshold 7500")

For these situations Dataminer thinks every time the RPM value changes is a new alarm and unmasks the alarm.

Any strategies to deal with these kind of situations that you recommend?

Thank you.

Best regards

Hi Bruno, If these are short bursts in the fan speed, you can probably use hysteresis on your alarm template to prevent the alarm from being generated if it is a momentary spike. If the high rpm lasts for longer than the set hysteresis interval, the alarm will still be generated.

Hello Michiel,

Thank you for the suggestion.

Unfortunately in this case hystereris is not an option though..
