The invention relates to a bus system (1) that has a control unit (2) and at least one bus subscriber (3.1, 3.2, 3.3). The control unit (2) has at least two associated data communication interfaces (2.1, 2.2) that are each designed to send and receive data. The at least one bus subscriber (3.1, 3.2, 3.3) has a bus coupler having at least two data communication interfaces (3.11, 3.12; 3.21, 3.22; 3.31, 3.32) that are each designed to send and receive data. The control unit (2) and the at least one bus subscriber (3.1, 3.2, 3.3) are connected to one another via their respective data communication interfaces and corresponding two-point connections (8) to form a ring topology. The bus coupler of the at least one bus subscriber is designed to send and hence forward data that are received on one of its at least two data communication interfaces via its other data communication interface directly and without delay. |
