Alarm Tag That Points to Other Tags

Hello,

Is there a way to make an alarm tag that points to x number of tags and will alarm if any or all of those tags meet the condition?

For example these two tags are set up the same way alarm wise and I have about one hundred more tags that will be set up the same way as these two

I am looking for a way to save some time instead of setting up hundreds of tags with the same alarm structure.

Is there a way to copy and paste the alarm setting in perspective?

Anything helps, let me know if I need to clarify.

Thank you

Create a UDT with parameters. Preset the alarm instance with the common attributes. For those attributes that are unique to each tag, use the defined parameters with {} substitution. As an example, I have a valve UDT with the normal 4 alarms (open, close, both, neither feedbacks). The parameter is the valve ID string. The alarm is “{ID} Open Alarm”.

Then, create your tag instances of type UDT and simply change the parameter for each instance.

I’ll have to try that out. I am experimenting with the script console and see if I can set up the historian and alarm tags all the same way

Definitely a UDT makes sense here.
I set my alarms up differently though. I set the:

  • Name: the alarm name, no context. Eg Failed to Start
  • Label: the equipment name and equip id. Eg Acid Dosing Pump [CRWDP001]
  • Display path: the plant area. Eg Crushers West

This way you can provide as much or as little context as you need in different places.
Eg
Equipment faceplates: Name only
Plant area alarm view: Label and Name only
Site alarm view: All three

Note also, you can change the texts 'Label' and 'Disaply Path' with the translation manager to something more appropriate like Device and Area
