Tag Report Tool: OPC Value not appearing

Ignition
1

Within the tag report tool, I am trying to query tags where the tag name = Label and the value is LIKE TT. The tag Label is an OPC Tag.

I have a udt instance which has a Label tag with value 'TT1310B', and here was my query:

with 0 results. As soon as i change the tag to memory, the tag query results have the tag i was searching for.

Is there a problem with reading the Value from an OPC tag within the tag report tool?

Also, if i remove the Value condition, so just the name = 'Label', the tag is in the query results

Yes. The tag report tool only looks at configuration. Only Memory tags have their value as part of persistent configuration.

Thanks for the reply @pturmel !

Is there any reason why it would work for some tags? i.e. one of my tags has a Label value of 'LT1417' and it correctly displays in the results. I even change it to something different in the PLC just to test, 'LT1417B' and that also displays in the query.

Hmm. Not sure.

So i think it is related to this post here:

I basically deleted the value within the tag (Ctrl+A then Delete), and then typed out the value manually. It returns in the query!

So maybe some newline characters or something that we couldn't see.
