PI Adapter for OPC UA Array Support
As a PI System Administrator, I would like for the PI Adapter for OPC UA to support array data types from the OPC UA Server. A large amount of our data may be contained within arrays on our OPC UA Server, so we would not currently be able to collect that data.
The array support is important in order to store dynamic data data, such as waveforms and FFT, which are then presented as graphs. The array functionality is supported in OPC DA, so it makes sense to have it in OPC UA as well, otherwise we have to add a third-party wrapper.

It would important for Time Array to be supported (one array with Time, one with Value), similar to how this is done in the Time Array Plug In for the OPC DA Interface
It is more efficient to transfer struc or array to reduce the load on the OPC server. The adapter should be able to read the child nodes of struc or array data types, for they are simple data types.
