DEVICE AND METHOD FOR ADDRESSING A SLAVE UNIT

The invention relates to a dynamically addressable slave unit, comprising a bus interface, a release circuit with a switch and two control connections that are connected via the release circuit. The release circuit only releases the slave unit for assigning an address by an address signal provided at the bus interface, when a control signal is provided at one of the control connections and when the switch of the release circuit is open. Otherwise, the release circuit locks the slave unit for assigning an address. Depending on a switching signal provided at the bus interface directed to the address assigned to the slave unit, the switch locks. The invention further relates to a master unit for use with one or more dynamically addressable slave units, to slave units according to the invention and to a method for dynamically addressing slave units according to the invention.
