摘要： The invention relates to a method for synchronizing nodes of a communication system comprising the following steps: receipt of a first synchronization message by a first node, whereby the first synchronization message contains a desired receipt time by a first node; correction of a time base of the first node, based on a deviation between an actual receipt time, determined as a result of the base time, and the desired receipt time.

摘要： The present invention is directed to a method of operation and a control program for a central unit (e.g., CPU) in an automation system repeatedly executing a control program that is stored in the central unit and comprises at least two subprograms. A single instance of execution occurs within a cycle time which is stipulated by the control program. The central unit executes only one of the subprograms—the activated subprogram—at a time. The cycle time is independent of the activated subprogram, is shorter than the time required in order to execute all of the subprograms, and is at least as long as the longest time period required in order to execute one of the subprograms once.

摘要： The invention relates to a synchronous, clocked communication system, for example a distributed automation system, the stations of which can be arbitrary automation components which are coupled to one another via a data network (1) for the purpose of mutual data exchange. In this arrangement, all possible bus systems such as, e.g. field bus, professional field bus, Ethernet, industrial Ethernet etc. are available for use as the data network (1) of the communication system. One station of this communication system is designated as timing generator and ensures the distribution and maintenance of the communication clock used to and by all stations. The timing generator can also introduce a relative clock (9) in the entire communication system at all stations via the same mechanism. This station is thus also the master of the relative clock (9) or the applicable relative time (16). All stations of the communication system are, therefore, continuously synchronized to the relative clock (9), which is applicable throughout this system, with the valid relative time (16) and, therefore have the same understanding of time at any time. This distinctly improves or even makes possible, respectively, the implementation of applicative sequences, synchronization of events occurring simultaneously, accuracy in time during the detection of events or, respectively, switching of outputs.
