Ereignisse

Erstellen von Auslösern zur Aktivierung anderer Systeme

Lösen Sie Aktionen innerhalb Ihres Stateflow^®-Diagramms oder anderer Simulink^®-Subsysteme aus, indem Sie Ereignisse verwenden. Lösen Sie externe Aktionen aus, indem Sie Ereignisse an andere Diagramme in Ihrem Simulink-Modell senden. Weitere Informationen zum Senden von Ereignissen an den Schedule Editor, um die Ausführung von aperiodischen Partitionen zu planen, finden Sie unter Events in Schedule Editor (Simulink).

Stateflow Syntax

Operatoren

Generieren von Ereignissen

`send`	Übertragen einer Meldung oder eines Ereignisses
`change`	Erzeugen eines impliziten Ereignisses, wenn Daten ihren Wert ändern
`enter`	Erzeugen eines impliziten Ereignisses, wenn der Zustand aktiv wird
`exit`	Generate implicit event when state becomes inactive

Ereignisbasierte temporale Logik

`after`	Ausführen des Diagramms nach der Übertragung eines Ereignisses oder nach einer bestimmten Zeit
`at`	Execute chart at event broadcast or specified time
`before`	Execute chart before event broadcast or specified time
`every`	Execute chart at regular intervals
`temporalCount`	Number of events, chart executions, or time since state became active
