Dear friends,

I am currently in the process of mapping a set of Newly Created/ Modified Tags for an existing System in a Platform.

Example:

  

OldNew
PI Tag12FT101.PV12FT-101.PV
Instrument TagMTR1/12FT101.PV.CV12FT101.PV.CV
What ChangedOld SystemNew DCS System

 

The Original Tag was in an Old System and was directly linked to PI, it was then migrated to the New DCS System and then re-linked in PI using the newly assigned InstrumentTag in DCS new Tag.
