I would like to use the value of a tag to perform calculations. Datalink pulls in the Digital State. Is there any way to get the raw number?
You may use PE expression SteNo instead of passing tagname directly.
I dont think you can use StateNo in PI Datalink compressed data item directly.
Request you to extract raw data for the time period using normal compressed data funtionality. Using Timed Data option you can use expression and get corresponding digital state.
