Hello,
We are building the SCADA system using Ignition. The system will monitor temperatures and alarm when deviation occurs.
I have a question regarding alarm notification pipelines and shelving/unshelving the active alarms. I have noticed that when the alarm is shelved then it will drop the pipeline (as per pipeline configuration), but when I unshelve it manually or when the time elapses then the alarm won't enter the notification pipeline again. Is it normal? Is there a way to force an alarm to enter the pipeline again when it is unshelved?
Thank you for your help.
Best regards,
Don't let the pipeline exit based on the shelved status. Just have the original pipeline loop based on the shelved status.
I have a few loops in my pipelines that uses an expression block, delay, and notification. In that expression block you can have it check for 'Is Shelved?' have have it go to the delay block again instead of the notification or whatever block you want.
That should solve it, thank you for your help.
