Do you know coding with C#? You could do a loop and subscribe in that for each loop to all the signal you need.
Yes, im using C#. Thanks for the advise, done for loop to subscribe all nodes.
But then when all nodes using public void NodeChanged(OPCUANodeSubscription sub, object obj), when value change, I can't trace which node is. Can you give us example?
Answer
The OPCUANodeSubscription object includes everything you need, e.g. the NodeID of the node which changed.
