Abstract
Die Erfindung betrifft ein Bussystem, mit einem Bus, an welchen wenigstens ein Master, ein Ausgangsslave und ein Sicherheitsmonitor angeschlossen sind. Der Ausgangsslave steuert einen Ausgangsschalter. Der Sicherheitsmonitor steuert einen Hauptschalter, welcher mit dem Ausgangsschalter in Reihe geschaltet ist. Über diese Schalter ist ein Verbraucher an eine Stromversorgung angeschlossen. Der Master gibt dem Ausgangsslave per Steuerbefehl den Soll-Schaltzustand des Ausgangsschalters vor. Der Ausgangsslave liest den Steuerbefehl ein und meldet den darin enthaltenen Soll-Schaltzustand auf den Bus zurück. Durch ein Zeitglied wird die Ausführung des Steuerbefehls für eine vorgegebene Wartezeit verzögert. Der Sicherheitsmonitor nimmt entweder eine positive Bewertung vor, wonach der zurückgemeldete Soll-Schaltzustand zulässig ist, oder nimmt eine negative Bewertung vor, wonach der zurückgemeldete Soll-Schaltzustand unzulässig ist. Bei negativer Bewertung wird der Hauptschalter geöffnet und somit der Verbraucher von der Stromversorgung getrennt. Die Wartezeit ist so lang bemessen, dass bei negativer Bewertung der Hauptschalter bereits geöffnet ist, bevor der Ausgangsschalter auf Steuerbefehl anspricht.
