HasCauseReferenceType | NodeOPCUA reference documentation

HasCause The HasCause ReferenceType is a concrete ReferenceType and can be used directly. It is a subtype of NonHierarchicalReferences.

The semantic of this ReferenceType is to point form a Transition to something that causes the Transition. In this annex we only define Methods as Causes. However, the ReferenceType is not restricted to point to Methods. The referenced Methods can, but do not have to point to a Method of the StateMachineType. For example, it is allowed to point to a server-wide restart Method leading the state machine to go into its initial state.

The SourceNode of this ReferenceType shall be an Object of the ObjectType TransitionType or one of its subtypes. The TargetNode can be of any NodeClass

Readonly isAbstract

isAbstract: boolean

Readonly nodeClass

nodeClass: ReferenceType

Readonly nodeId

nodeId: NodeId

Optional nodeVersion

nodeVersion: UAVariableT<string, String>

NodeVersion (Optional) String The NodeVersion Property is used to indicate the version of a Node. The NodeVersion Property is updated each time a Reference is added or deleted to the Node the Property belongs to. Attribute value changes do not cause the NodeVersion to change. Clients may read the NodeVersion Property or subscribe to it to determine when the structure of a Node has changed.
