Die Erfindung betrifft eine Anordnung zur Zeitsynchronisation von industriellen Anlagen, Gebäudeleitsystemen und/oder vernetzten Bürosystemen, mit einer Zeitsynchronisationseinrichtung gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to an arrangement for time synchronization of industrial systems, building management systems and / or networked office systems, with a time synchronization device according to the preamble of patent claim 1.

In verteilten Systemen, wie industriellen Anlagen, Versorgungs- oder Kommunikationseinrichtungen in Gebäuden oder Büroeinrichtungen ist für bestimmte Prozesse oder zur Fehlerdiagnose eine zeitliche Synchronisation einzelner Anlagenteile oder Einrichtungen wichtig. Bei vernetzten Anlagen wird deshalb z. B. ein Zeitstempel über ein Netzwerk mit übertragen. Bei nicht vernetzten Anlagenteilen werden diese mittels je eines separaten Moduls, das z. B. als Zusatzteil in einer speicherprogrammierbaren Steuerung (SPS) ausgebildet sein kann, synchronisiert. Solche separate Hardwarekonfigurationen sind jedoch vergleichsweise aufwendig und teuer.In distributed systems, such as industrial plants, supply or communication facilities in buildings or office facilities, timing of individual plant parts or facilities is important for certain processes or for fault diagnosis. For networked systems is therefore z. B. transmitted a timestamp over a network. In non-networked system components, these are each using a separate module, the z. B. can be configured as an additional part in a programmable logic controller (PLC), synchronized. However, such separate hardware configurations are comparatively expensive and expensive.

Aus der DE 296 01 332 U1 ist eine Nebenuhrenanlage bekannt, die aus einer zentralen Steuereinheit für die gleichzeitige Ansteuerung mehrerer analoger Nebenuhren vorgesehen ist. Dabei wird ein Datenleitungssystem zur Übermittlung der Zeitinformation verwendet, wobei die Nebenuhren jeweils einen Mikroprozessor zur Datendecodierung und Funktionssteuerung aufweisen. Weiterhin ist aus der DE 38 03 525 A1 eine Vorrichtung zum Betrieb von Echtzeituhren bekannt, bei denen die Echtzeit von einer Zentraluhr vorgegeben und über die vorhandenen Bussysteme an die einzelnen Teilnehmer weitergeleitet wird.From the DE 296 01 332 U1 a slave clock system is known, which is provided from a central control unit for the simultaneous control of several analog slave clocks.

Eine derartige Zeitsynchronisationseinrichtung ist deutlich kostengünstiger als die bekannten Anordnungen mit Zeitsynchronisationseinrichtungen.In the invention, a time synchronization device is used, which synchronizes several parts of the system, wherein the adaptation to the corresponding system parts is carried out by a corresponding parameterization of the time synchronization device.
