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.

Syntax

[OpcNodeType(58)]
public class OpcObjectNode : OpcInstanceNode

<OpcNodeType(58)>
Public Class OpcObjectNode
    Inherits OpcInstanceNode

Inheritance

Object → OpcNode → OpcInstanceNode → OpcObjectNode

Implements

• IOpcNode
• IOpcNodeInfo

Derived types

• OpcAggregateConfigurationNode
• OpcEventNode
• OpcFileNode
• OpcFolderNode
• OpcHistoryConfigurationNode
• OpcOrderedObjectListNode

• OpcTransitionNode

Remarks

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.
