Vermeidung von Fehlalarmen in Not-Aus-Systemen: Ein technischer Leitfaden

  • 〡 von WUPAMBO

In der industriellen Automatisierung ist der Not-Aus-Taster (E-Stop) die letzte Sicherheitslinie. Das Verlassen auf einen einzelnen normalerweise geschlossenen (NC) Kontakt kann jedoch manchmal zu unerwarteten Fehlabschaltungen führen. Als Steuerungssystemingenieur habe ich erlebt, wie diese Störabschaltungen ganze Produktionslinien zum Stillstand brachten und erhebliche Ausfallzeiten verursachten. Zu verstehen, warum diese Komponenten ausfallen und wie man eine robuste Architektur implementiert, ist für jedes zuverlässige DCS- oder SPS-basierte Sicherheitssystem unerlässlich.
