Abstract
In the case of a data bus for several users, the users have hierarchical transmission authorizations; the users are synchronized by a synchronization signal; and the communication of the user with the highest priority, which can be emitted at regular time intervals by this user, serves as a synchronization signal.
Claims8
Data bus for several users, wherein
- a) the users possess hierarchical transmission authorizations,
- b) the users are synchronized by a synchronization signal, and
- c) the communication of a user with the highest priority, which can be emitted by this user at regular intervals, is used as the synchronization signal.
A method for operating a data bus on which several users are arranged, the method comprising the acts of:
- assigning hierarchical transmission authorization to the several users on the data bus;
- synchronizing hierarchical transmission of the users via a synchronization signal;
- and
- using as the synchronization signal communications of the user assigned a highest priority that is capable of transmitting said communication at regular intervals.
