Abstract

Die Erfindung betrifft ein Verfahren zum Betreiben eines Datennetzwerks (20), welches eine Mehrzahl von Endgeräten (12a, b, c) umfasst, die untereinander Daten austauschen und von wenigstens einem Netzknoten (11) bzw. von wenigstens einem der Endgeräte (13) mit interner Versorgung mit Speiseleistung auf einem vorgegebenen nominalen Spannungspegel versorgt werden. Eine vereinfachte und flexible prioritäts-bestimmte Steuerung des Netzbetriebs wird dadurch erreicht, dass die Endgeräte (12a, b, c) in Klassen mit unterschiedlich hoher Priorität eingeordnet werden, und dass beim Absinken des Spannungspegels unter den Nominalwert mit fallendem Spannungspegel die Endgeräte (12a, b, c) in einer durch ihre Priorität gegebenen Reihenfolge abgeschaltet werden, wobei zuerst die Endgeräte mit der niedrigsten Priorität ausgeschaltet werden.
