Well, which of?
OPC DA is, truth to tell, garbage.
OPC UA is under permanent development. It is impossible to say when it
will reach even a semi-standard stage.
Regarding architecture, OPC is barely usable in automation because of
its heavy client/server architecture. Part of our business is to replace
OPC with better middleware architectures. Replacement works smoothly
because in most cases you can throw out the OPC server and communicate
with the hardware directly. E.g. most SPS' support either ITOT or
ModBus, each far superior to OPC.

Cannot comment on it. I am familiar with Softing OPC DA stack and with
Unified Automation OPC UA stack.
