Abstract
Subject of the invention is a serial bus system with two data lines (10, 12), connected at one end to a central bus subscriber (14) and to an active bus subscriber at the other end (16). The central and the active bus subscriber transmits status messages over the bus (10, 12) whose bus lines are physically passed through in the bus subscribers (18, 20) between the two ends. In case of missing status messages or error in the status messages, the central bus subscriber (14) brings the bus system into a fail-safe state.
