Abstract
The invention relates to a bus system (1) comprising a control unit (2) and at least one bus node (3.1, 3.2, 3.3). The control unit (2) is allocated at least two data communication interfaces (2.1, 2.2) which are respectively designed to transmit and receive data. The at least one bus node (3.1, 3.2, 3.3) comprises a bus coupler having at least two data communication interfaces (3.11, 3.12; 3.21, 3.22; 3.31, 3.32) respectively designed to transmit and receive data. The control unit (2) and the at least one bus node (3.1, 3.2, 3.3) are respectively connected together via their data communication interfaces and corresponding two-point connections (8) to form a ring topology. The bus coupler of the at least one bus node is designed to directly and without delay transmit, and thus forward, data received at one of its at least two communication interfaces via its other data communication interface.
