I have about 19,000 PI tags that I need to check the most recent value for. My goal is to delete any of the tags whose most recent value is "Pt Created". This is because no data has been written to these tags and therefor can be deleted.
I want to know if there is a way to automate this process (or at the very least speed things up).
- I have all the tag names in an Excel spreadsheet
- I don't think using macros or VB will work, I'm not aware of the functions that PI Datalink uses
Appreciate any help that you can provide.
