Create triggers to activate other systems

Trigger actions within your Stateflow® chart or other Simulink® subsystems by using events. Trigger external actions by sending events to other charts in your Simulink model. For more information on sending events to the Schedule Editor to schedule the execution of aperiodic partitions, see Events in Schedule Editor (Simulink).
