Abstract

A method for transmitting data from at least one sensor to a control unit via an appropriate two-wire line is described. The method is used to identify any sensor at the control unit and to implement a plurality of logical channels via the appropriate two-wire line. The at least one sensor receives the necessary electrical energy from the control unit via the two-wire line and then transmits the sensor-specific data.
