At least one first component is operable in a sleep operating mode avoiding electromagnetic interference signals. A first component in the sleep operating mode is placed at least temporarily into the normal operating mode upon receiving a communication message via a bus system. The first and second components along at least one communication pathway are each arranged such that all first components are provided at an end of the communication pathway distant from a master component as a bus segment connected directly downstream of at least one of the second components and containing exclusively first components. At least the second component of each communication pathway that is provided directly adjacent to the bus segment in the communication pathway has a switch for temporarily blocking the communication forwarding on the communication line of the line connection assigned to the bus segment and a controller for actuating the switch.
