If you planning to store error codes then would suggest you to create a digital set with all error codes/description and assign it to your PI Point . e.g. You can take a look at "System" digital state. Once mapped to digital tag you can visual the same in visualisation tool like PI Vision /PB. You can use PI Builder to export 600 codes with description into to PI.
Thanks for the prompt reply. Ok I created a digital set with all my error codes...
Then I created a digital tag mapped to the digital set and the source tag from the original tag that displays current error code...
I'm not getting anything from this new tag. When an error occurs nothing happens. I think my whole thinking on this is a little skewed.
Once this tag works how would I cohesively display this in Processbook? Ideally, I'd love to show a list of 10 most frequent error codes.
What is the data type of the source data for the 'error codes' tag?
In other words, what did the values look like before switching to a digital set? Where the values coming in as strings with the actual written out full length error message? or were they coming in as integer codes?
If the values are originally coming in as integer values, you simply need to make the 'error codes' tag a Digital tag mapped to the set you made instead of making it a source tag for a new tag.
