Japanese Patent JP2006525725
Kind Code:
A
Abstract:
The invention relates to a method of transmitting user data via a communications medium ( 2 ) between subscribers ( 3 ) connected to the communications medium ( 2 ), wherein the data are transmitted in recurrent cycles ( 8 ) and at least one slot ( 9, 10 ) in each cycle ( 8 ) is intended for the user data of at least one subscriber ( 3 ). In order to permit a particularly efficient data transmission via the communications medium ( 2 ) at least one of the slots ( 10 ) is used to transmit the user data of different subscribers ( 3 ) (A, C, F) in different cycles ( 8 ). In addition, a bus guardian ( 6 ) of one subscriber ( 3 ) determines whether the subscriber ( 3 ) may transmit user data in the current slot ( 9, 10 ) of the current cycle ( 8 ), the bus guardian ( 6 ) having at least indirect access to a universal condition available throughout the entire communications system ( 1 ). In particular, an internal counter of the bus guardian ( 6 ) is synchronized to a universal cycle counter.
