I have a script that I want to run every time a new alarm is active/cleared. This script updates a bunch of graphics and tags. Currently that script is located in a GW timer Script that runs every 10 seconds. I would prefer if I could trigger this script only when an alarm active/cleared event is triggered. Running the script every 10 seconds will become resource intensive as the project grows.

I was thinking of using the alarm notification module (which we already have) as a way of handling alarm events in a “report by exception” manner instead of a polling manner. But then I would be creating a pipeline that triggers a script and not notify anyone.

Is this the best way to achieve this or am I overcomplicating it by making use of an additional module? Is there a simpler/ best practice approach?

I would mix them as Method 3: Use a tag change script to monitor all of the pressures, and update a single timestamp memory tag when a pressure change yields a color change. Use a timer script (not a tag change) to check the timestamp tag every few seconds (or 10, perhaps) and regenerate the markup when changed.
