OpcObjectNode Class

Namespace: Opc.UaFx
Assemblies: Opc.UaFx.Advanced.dll

Defines a logical unit to represent more complex information as a OpcVariableNode. Objects are used to represent systems, system components, real-world objects and software objects.

From a more abstract point of view objects are used to group variables and other objects in the address space. Therefore objects should be used when some common structures/groups of objects and/or variables should be described.

Simple objects only having one value (e.g. a simple heat sensor) can also be modelled as variables. However, extensibility mechanisms should be considered (e.g. a complex heat sensor subtype could have several values) and whether that object should be exposed as an object in the client's GUI or just as a value. Whenever a modeller is in doubt as to which solution to use the object having one variable should be preferred.
