OPC UA in ver 14.3. I would like to replace my PI to PI with OPC UA interface. DeltaV Advanced Continuous Historian to site OSI PI server.

Has anyone used the OPC UA to pass PI information from Advanced Continuous Historian to site PI ?   We are currently using PI to PI for our PI interface node and would like to see if OPC UA could be utilized here.

  Matthew, I've reached out to the factory for clarity on this. According to Books on Line, the Advanced Continuous Historian is compatible with PI Datalink, PI Manual Logger, and PI to PI. BOL explicitly states "other OSIsoft client applications are not compatible". It is my understanding that with Advanced Continuous Historian, you must use PI to PI to move this data up to your PI enterprise server. I don't believe the OPC UA Connector can be used to access the data stored in the Advanced Continuous Historian. This is something I'm trying to confirm with the factory.
  
  OSIsoft have an OPC UA connector which is used to move data from a PI interface to the PI Archives and Asset Frame (AF). The OPC UA connector would access runtime data from the DeltaV OPC UA server. The Connector automatically buffers data so that a loss of network access will not result in loss of Data. Buffered data is processed into the Enterprise server when connection is restored.
  
  This will require the OPC tags be licensed in DeltaV for the OPC UA Connector. The Advanced Continuous Historian licensing is separate.
