I am backfilling history data using OPCHDA from Exaquantum server to PI. I constantly received the following error message:
Unable to release itemID xxxx.pv.value for tag xxxx.PV hr = 80004005, PIOPCHDAInt, , PIOPCHDAInt
This normally will report all the tags one by one, then OPCHDA interface exits. No data gets populated from interface. What could it go wrong?
