Abstract

A bus system includes at least two data buses, the first data bus having a first number of users and the second data bus having a second number of users. At least two TTCAN buses, which are interlinked by users connected simultaneously to both TTCAN buses, are used as the data buses. Fewer users than the sum of the number of users of the first TTCAN bus and the number of users of the second TTCAN bus are connected to the two TTCAN buses at the same time. A generating arrangement is included to generate a scalable fault tolerance in the bus system as a function of the number of users connected to the at least two TTCAN buses at the same time.
