Re: [milo-dev] Unable to subscribe to OPC-UA server node

[Kevin Herron <kevinherron@xxxxxxxxx>]

The NodeId in your screenshot from UaExpert is using a NodeId with an integer identifier and the code sample you've provided is using a String identifier.

Try removing the quotes: new NodeId(2, 6051)

Hi team,

 

I am trying subscribe to opc-ua server Node value change using milo.opc-ua client-examples project, following is the code changed to test it using SubscriptionExample class

 

  ReadValueId readValueId = new ReadValueId( new NodeId(2,"6051"),

  AttributeId.Value.uid(), null, QualifiedName.NULL_VALUE );

 

But, I am getting this error

[main] WARN  o.e.m.e.client.SubscriptionExample - failed to create item for nodeId=NodeId{ns=2, id=5003} (status=StatusCode{name=Bad_NodeIdUnknown, value=0x80340000, quality=bad})

 

 

Its working in opc-ua UaExpert tool

 

Please provide required details/example to subscribe to opc-ua node to capture data on node change

 

Regards,

Pramod
