The ProgramTransitionEventType is a subtype of the TransitionEventType. It is used with Programs to acquire intermediate or final results or other data associated with a state transition. A Program can have a unique ProgramTransitionEventType definition for any transition. Each ProgramTransitionEventType specifies the IntermediateResult data specific to the designated state transition on that ProgramStateMachineType. Each transition can yield different intermediate result data. Table 9 specifies the ProgramTransitionEventType.
Table 10 identifies the ProgramTransitionEventTypes that are specified for ProgramStateMachineTypes.

TransitionNumber identifies the Program transition that triggered the Event.
FromStateNumber identifies the state before the Program transition.
ToStateNumber identifies the state after the Program transition.
The IntermediateResult is an Object that aggregates a set of Variables whose values are relevant for the Program at the instant of the associated transition. The ObjectType for the IntermediateResult specifies the collection of Variables using a set of HasComponent References.
