Abstract:
1. A method for synchronization in a redundant communication system that includes a central participant and at least one further participant, comprising the steps of: synchronizing the at least one further participant with the central participant including transmitting at least two telegrams containing synchronization information by the central participant to the at least one further participant; based on the synchronization information contained in the at least two telegrams, forming resultant synchronization information; using said at least two telegrams to transmit process data in the form of set point values to said at least one further participant via data fields, wherein a length of each data field depends on an amount and type of data transmitted, wherein each of said at least two telegrams represents data blocks, and wherein a synchronization information field is embedded into each of said data fields; and using the resultant synchronization information to synchronize further participants with the central participant, wherein the communication system is a distributed communication serial real time communication system of an automation system with a plurality of conveying and operating elements harmonized with respect to time, and wherein each of said at least one further participant is a component of said automation system, wherein said components are selected from the group consisting of sensors, actors and drives.
