Hi Dears,

I begin to use the node opc-ua to read tags from a opc-ua server. I would like to know if is possible define a msg.payload tags list to enter in an unique OPC-UA-ITEM and after in an OPC-UA-CLIENT. Reading the node documentation, it seems to me that I have to define one tag per node opc-ua-item, which overloads the flow a lot.

Thanks,

Roberto

If you use client node and subscription you can inject nodeIds to input.
