Hi All,
I have UTD for which I have a custom property ‘asset_id’.
I then configured an alarm on a tag withing the UDT which also has a custom property ‘asset_id’ which I want bound to the UDT’s ‘asset_id’.
Is there a way to do this?
In trying to solve my issue in another way, I found that the expression language does not function on tags or tag custom properties the same as if they were on say a vision component. For instance, if I try create a tag within my UDT who’s value is split({PathToParentFolder}, "/")[3, 'parts'] it doesn’t work as expected.
Can you just try putting {asset_id} there?
Yea I tried that - no dice
Okay can you create one memory expression tag linked to the UDTs property and have alarms property referring to that expression tag?
Tried that too - Like I say, I think expressions don’t work exactly like they do in Vision - not sure if this is intended or not
I thought that worked for me but having tested more it doesn’t. @kcollins1, how does one create those videos so I can show my configuration?
If you’re on Windows, ShareX is FOSS and can screen record to GIF.
On MacOS, I like Kap (also FOSS), but others may have more informed opinions.
On Linux, I dunno, use ffmpeg or something

That's exactly what I do.

Hi Guys,
Sorry, wasn’t able to get to this until now. As you can see, the ‘label’ alarm property isn’t coming through to the email notification.

Submitted a ticket to IA support. Keaton Elliott helped me realize the alarm ‘Label’ property and ‘asset_name’ custom property needs to be expression syntax.
Like:
Label property: {asset_name} + ' Error'
asset_name custom property: {[.].asset_name} + '_p' + {InstanceName}
Now works as expected!
Hello everyone!
I'm facing a similar issue. I would like to access a Custom Property value using an Expression Tag. I've tried {asset_name} and {[.].asset_name} to get "CustomTest" text
Nevermind, using {[.]Test.asset_name} worked !
