Transitionsof a FiniteStateMachineare represented as Objectsof the ObjectType TransitionTypeformally defined in Table 9. Each Objectof the TransitionTypeor one of its subtypes shall be referenced from the ObjectType FiniteStateMachineTypeor one of its subtypes using a HasComponent Referenceor a subtype of HasComponentand shall not have a ModellingRuleas they are not applied on the instances.

Each valid Transitionshall have exactly one FromState Referenceand exactly one ToState Reference, each pointing to an Objectof the ObjectType StateType.

Each Transitioncan have one or more HasCause Referencespointing to the cause that triggers the Transition.

Each Transitioncan have one or more HasEffect Referencespointing to the effects that occur when the Transitionwas triggered.
