PI Adapter for OPC UA should be able to write outputs to the OPC UA Server
The PI Adapter should be able to create a data pipe listener on certain streams (unsolicited reads) that would trigger the writes back to the OPC UA Server.
This is useful when providing set points to the equipment without the need of establishing a second (DA to UA) data flow in parallel.
Ability to write back is essential, frustrated we are still waiting for this to be actioned.
We need this feature to replace our old OPC DA Interfaces. Otherwise we wont be able to switch to PI Adapters.
