Hello Pi Square:
I'm about to embark on a installation that involves a Factory Talk View Data Historian (has a built in Pi archive) and another Pi archive. Rockwell does not allow a connection to it's historian directly so a Pi to Pi interface needs to be setup.
I have setup numerous OPC-DA interfaces and know about setting up a trust first and that data flows in only one direction: in our case it will be from the FTView ("HIST_A") to our Pi archive ("HIST_B").
My question revolves around the tagnames:
1.) Do pipoint names have to be exact on both sides? (I think not but just to be safe)
2.) Does the fieldname for the Instrument tag on HIST_B get the pipoint name from HIST_A?
3.) I have started to read the manual but just looking for landmines before I start the journey.
