ReadNodeId Method



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.Extensions Namespace > IEasyUAClientExtension2 Class : ReadNodeId Method
Reads a value of NodeId attribute of a node. If successful, the method returns the actual value of OPC attribute requested.

This method also checks whether the returned value is not a reference, and is indeed of the OpcLabs.EasyOpc.UA.AddressSpace.UANodeId type. The returned value is therefore always a valid OpcLabs.EasyOpc.UA.AddressSpace.UANodeId.
