Re: [milo-dev] How to differentiate while subscribing nodes with the sam

[J Dhanasekar <jdhanasekar@xxxxxxxxxxxxxxxxxx>]

I am seeing string values for NodeID, instead of Numeric value,

How to point out particular dummy nodes(when two dummy nodes exist with the same name) while subscribing a node ?

Nodes are identified by their NodeId, not their Browse Name, and are guaranteed to be unique within a server.

If you are connecting to multiple servers, you will have multiple instances of OpcUaClient (one per server), and your application would be responsible for doing the bookkeeping of which set of NodeIds belong to which server connection.

Hi Milo,

I am running two ProsysSimulationServer in two different systems. For demo purposes, I am subscribing to the same set of nodes from both Simulation Server.

I have created dummy node like this,

For ProsysSimulationServer2, When I run subscription.java, I am not getting any error but values from actually ProsysSimulationServer are not reflected in the dummy node. 

For ProsysSimulationServer_ReadOnly, I am getting error like this, 

16:29:33.655 [main] WARN  o.e.m.e.c.ProsysSimulationServer - failed to create item for nodeId=NodeId{ns=1, id=1002} (status=StatusCode{name=Bad_NodeIdUnknown, value=0x80340000, quality=bad})

How to differentiate these two sets of dummy nodes if only subscription works properly?

How to differentiate while subscribing nodes with the same Name?

Thanks,

Dhanasekar
