Abstract
Die Erfindung betrifft eine Anordnung zur Verarbeitung von Zeitbefehlen. Für viele Anwendungen in der Datenverarbeitung, z. B. in speicherprogrammierbaren Steuerungen, benötigt man programmierbare Zeiten zur zeitabhängigen Steuerung von Ab läufen. Eine möglichst schnelle Verfügbarkeit eines aktuellen Zeitwertes nach einer Zeitabfrage wird dadurch erreicht, daß ein Zeitspeicher (ZS) einen ersten Speicher (S1) und einen zweiten Speicher (S2) aufweist und daß eine Bearbeitungslogik (BL), mit einem Taktsignal gesteuert, wechselweise aus dem einen Speicher (S1, S2) gespeicherte Zeitwerte ausliest, be arbeitet und in den anderen Speicher (S2, S1) einschreibt und bei einer Zeitabfrage den jeweils gültigen Zeitwert bereit stellt. The invention relates to an arrangement for processing Time commands. For many applications in data processing, e.g. B. in programmable logic controllers, you need programmable times for time-dependent control of Ab run. The fastest possible availability of a current one Time value after a time query is achieved in that a time memory (ZS), a first memory (S1) and one second memory (S2) and that a processing logic (BL), controlled with a clock signal, alternately from the reads out a stored time value (S1, S2), be works and writes in the other memory (S2, S1) and in the case of a time query, the current time value is ready poses.
Die Erfindung wird angewendet in Datenverarbeitungsanlagen, insbesondere in speicherprogrammierbaren Steuereinheiten. The invention is applied in data processing systems, especially in programmable logic controllers.
