Abstract

Eine elektronische Steuereinheit enthält eine serielle Kommunikationsschaltung mit der Fähigkeit zum einfachen Bestätigen des Vorliegens oder Nichtvorliegens eines Kommunikationsfehlers während dem zeitnahen Ausführen eines Regulärübertragungs-/Regulärberichts zwischen einer Master-Station und einer Unterstation. Ein erster und ein zweiter Steuerschaltungsabschnitt (200a, Masterstation und 200b, Unterstation) kommunizieren wechselseitig über Serien/Parallel-Umsetzer (117, 127). Die Masterstation enthält eine Regulär-Übertragungsvorrichtung (201) und eine Irregulär-Übertragungsvorrichtung (211). Die Unterstation enthält eine Regulär-Berichtsvorrichtung (221), eine Bestätigungserwiderungseinrichtung (205) und eine Berichtserwiderungseinrichtung (215) relativ zu Übertragungsdaten von der Masterstation, und eine Tabelle nicht verarbeiteter Daten (204). Die Bestätigungserwiderungseinrichtung (205) und die Berichtserwiderungseinrichtung (215) bestätigen, ob eine Stromabwärts-Kommunikation von der Masterstation zu der Unterstation normal ist oder nicht. Liegt irgendein Fehler in Regulär-Berichtsdaten über eine Stromaufwärts-Kommunikation vor, so wird der Fehler an der Tatsache bestätigt, dass die Irregulär-Übertragungseinrichtung (211) eine Neuübertragungs-Ausleseanforderung ausführt.
