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.
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 in each cycle (8) at least one slot (9, 10) is intended for the user data of at least one subscriber (3),
A subscriber (3) which can be connected to a communications medium (2) for the transmission of user data via the communications medium (2) to further subscribers (3) that can be 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), characterized in that at least one of the slots (10) is intended for the transmission of the user data of different subscribers (3) in different cycles (8) and the subscriber (3) in a predefinable cycle (8) transmits user data in the shared slot (10) useable by multiple subscribers (3).
A bus guardian (6), which is assigned to a subscriber (3) connectable to a communications medium (2), wherein the subscriber (3) is designed for the transmission of user data via the communications medium (2) to further subscribers (3) connected to the communications medium (2), and 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), characterized in that at least one slot (9, 10) is provided, via which user data of different subscribers (3) can be transmitted in different cycles (8), wherein the bus guardian (6) determines whether the subscriber (3) may transmit user data in the current slot (10) of the current cycle (8).
A communications system (1) comprising a communications medium (2) and a plurality of subscribers (3) connected thereto, wherein user data are transmitted between the subscribers (3) via the communications medium (2) 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), characterized in that at least one of the slots (10) is intended for the transmission of the user data of different subscribers (3) in different cycles (8).
