Hello All,

I have following scenario. I have 2 Node Manager as follows ANodeManager (contains ANode) and BNodeManager. Then how can I access/find ANode from BNodeManager. In the end, I want to link an object from BNodeManager to ANode.

 

In BNodeManager, I tried using Find or FindPredefinedNode as shown below. But the result is null.

NodeId nodeId = new NodeId(Objects.ANode, NamespaceIndexofANodeManager);

BaseObjectState ANode = (BaseObjectState)FindPredefinedNode(nodeId, typeof(BaseObjectState));

 

For checking, I also tried to check whether the FindPredefinedNode method work for in ANodeManager. At that time, it find the node correctly.

As per the boiler example, it should works. Am I missing anything here?

Thanks in advance!

Use a FindNodeInAddressSpace instead of FindPredefinedNode. Also input NodeId with correct Namespace.

You need a reference to ANodeManager in BNodeManager and call a Method on ANodeManager .
