ChainedTransitions

This model shows how Ptolemy II handles the "chained" transitions.

By chained transitions, it means that when a state is entered through an incoming transition, at least one of its outgoing transitions is enabled, and the enabled transition is taken immediately without advancing the time. The state is called a "transient" state.

Note, the actions associated with both the incoming and outgoing transitions are executed.

The block diagram for the model was constructed using the Ptolemy II schematic editor called Vergil.
