Abstract

A bus station and a bus system in which two bus stations are connected by at least one bus conductor. Messages are transmitted via a current flowing over the bus conductor. The bus station is supplied with operating current over the bus conductor. For this purpose, an energy storage device stores operating energy. In order to transmit messages, the bus station closes the switch and thus generates a current flow, which discharges the energy storage device of the bus station via the switch and resistor. The station transmits messages by causing the current to flow in the opposite direction by closing the switch. In order to prevent the energy storage device from discharging, the switch is opened.
