Abstract
In a method for time synchronization of subscribers connected via a cyclically operating communication system, an item of time information is transmitted to the subscribers to be synchronized. It is provided to transmit an item of absolute time information simultaneously to all subscribers to be synchronized, for initialization, and to implement a synchronization by recalculating the local times of the subscribes at least following one or a plurality of cycles having a known cycle time. The item of absolute time information and the known cycle times are used for the recalculation.
Claims10
A method for time synchronization of subscribers connected via a cyclically operating communication system, the method comprising:
- transmitting an item of time information to the subscribers to be synchronized;
- simultaneously transmitting an item of absolute time information for initialization to all of the subscribers to be synchronized;
- and
- carrying out an individual synchronization by recalculating local times of the subscribers from the absolute time information and a cycle time in each case after at least one or a plurality of cycles having a known cycle time.
A subscriber of a cyclically operating communication system, comprising:
- a computing unit which is configured for time synchronization in such a way that, after receipt of an item of absolute time information, a local time of the subscriber is recalculated from the item of absolute time information and a cycle time, at least following one or a plurality of cycles having a known cycle time.
A cyclically operating communication system comprising a subscriber, the subscriber including:
- a computing unit which is configured for time synchronization in such a way that, after receipt of an item of absolute time information, a local time of the subscriber is recalculated from the item of absolute time information and a cycle time, at least following one or a plurality of cycles having a known cycle time.
