Abstract

A bus system with a master station and a plurality of slave stations is described. The slave stations have a connecting switch, with the downstream slave stations having no electric contact with the master station when the connecting switch of a first slave station is opened. In this phase, the first slave station is initialized. Before closing the connecting switch, a test switch is closed, with the current flow being limited by a current limiter. It is thus possible to check on whether the downstream slave station has a short circuit.
