A method for addressing each of the addressable participants (116.i) of a bus system, the bus system comprising a control unit, a bus coupled to the control unit, and a plurality of addressable participants (116.i) connected to the bus, the method comprising: a) pre-selecting at least a first number of addressable participants (116.i), the pre-selection comprising: - feeding by each of the addressable participants (116.i) not addressed so far of a pre-selection current, wherein all pre-selection currents flow through the bus towards the control unit, - measuring of the pre-selection current flowing through the bus by each of these participants (116.i), and - pre-selecting those participants (116.i) that measure a pre-selection current lower than a first threshold; b) selecting from the pre-selected participants (116.i) a second number of addressable participants (116.i), the second number being at least one, the selection comprising: - feeding by each of the pre-selected participants (116.i) of a selection current, wherein all selection currents flow through the bus towards the control unit; - measuring by each of the pre-selected participants (116.i) of the selection current flowing through the bus; - selecting the second number of participants (116.i) based on at least a second threshold, different from the first threshold; c) assigning a second number of addresses to each of the participants (116.i) selected in step b); d) repeating steps a) to c) without the participants (116.i) already being addressed, until all addressable participants (116.i) are addressed; characterised by: said pre-selection current fed by each addressable participant (116.i) is generated by a first current source providing a current substantially independent of the supply voltage. a) pre-selecting at least a first number of addressable participants (116.i), the pre-selection comprising: - feeding by each of the addressable participants (116.i) not addressed so far of a pre-selection current, wherein all pre-selection currents flow through the bus towards the control unit, - measuring of the pre-selection current flowing through the bus by each of these participants (116.i), and - pre-selecting those participants (116.i) that measure a pre-selection current lower than a first threshold; - feeding by each of the addressable participants (116.i) not addressed so far of a pre-selection current, wherein all pre-selection currents flow through the bus towards the control unit, - measuring of the pre-selection current flowing through the bus by each of these participants (116.i), and - pre-selecting those participants (116.i) that measure a pre-selection current lower than a first threshold; b) selecting from the pre-selected participants (116.i) a second number of addressable participants (116.i), the second number being at least one, the selection comprising: - feeding by each of the pre-selected participants (116.i) of a selection current, wherein all selection currents flow through the bus towards the control unit; - measuring by each of the pre-selected participants (116.i) of the selection current flowing through the bus; - selecting the second number of participants (116.i) based on at least a second threshold, different from the first threshold; - feeding by each of the pre-selected participants (116.i) of a selection current, wherein all selection currents flow through the bus towards the control unit; - measuring by each of the pre-selected participants (116.i) of the selection current flowing through the bus; - selecting the second number of participants (116.i) based on at least a second threshold, different from the first threshold; c) assigning a second number of addresses to each of the participants (116.i) selected in step b); d) repeating steps a) to c) without the participants (116.i) already being addressed, until all addressable participants (116.i) are addressed;
