Alarm hierarchy

Ignition

Hello all,

I have a question about alarm hierarchy functionality.

I would like less important alarms to be hidden/disabled/not shown in Alarm Status whenever a more important alarm is present.
Let us imagine that I have a tag for a level in a tank. On this tag, I set 2 alarms. One for “High Level” and another one for “Very High Level”.
The idea is to display (in an Alarm Status Table for example) the “High Level” alarm when it is present but to “hide” it when the “Very High Level” is present.

I guess it is called alarms hierarchy and / or alarms groups but I cannot find anything on the forum.

Is it possible to have such a behavior for the alarms ?

Thank you.

Hi,

if the alarms are on the same tag, then I would suggest you to take advantage of the alarm setpoint condition, i.e., instead of defining:

“High Level” active if level > x
“Very High Level” active if level > y

define:

“High Level” active if level > x and level <= y
“Very High Level” active if level > y

To do this, set the alarm mode as “Between Setpoints”. docs.inductiveautomation.com:84 … m+on+a+Tag

Hope it helps,

Good call when the alarms are on the same tag.

Thank you.
