All that you can do wrote in the documentation — http://oscada.org/wiki/Special:MyLanguage/Modules/OPC_UA
And OPC-UA operates by Nodes, not tags!
And you can easy define the Nodes in attributes for the Standard parameter type.
If you mean direct requesting OPC-UA, like to DAQ.ModBus messIO(string pdu), then the DAQ.OPC_UA module doesn't provide such function.
Learn, learn and learn better than work, work and work.
