PI interface for OPC .. UA
it would be useful to have an interface that can connect and retrieve data from OPC UA server. it will help to avoid using any additional software for "downgrading" the protocol to OPC at client side.

What downgrading is there?
If you need to get data from an OPC DA server into PI, then use the PI Interface For OPC DA.
If you need to get data from an OPC UA server into PI, then use the PI Connector For OPC UA or the PI Adapter For OPC UA.
