I have an installation where two computers, both with openPDC, are sending data to the same PI server, and both are set to create tags in PI. Both openPDC configurations were based on the same computer image and simply have a change in tag names for the devices they are connect to.
Depending on which PI historian instance is initialized first, the PI tag names are being replaced by the second historian instance instead of creating new tags. If the second instance is then disabled, the first instance will start updating the PI tags which now have the second instance’s tag names.
Is there a parameter I need to make sure doesn’t match between computers that could be causing this? Like I mentioned the only difference in openPDC configuration is tag names and descriptions.
