To guarantee assignment of an address to an addressable participant element even in the case of variance in supply voltage, number of participant elements on a bus, etc.
A method for addressing each of a plurality of addressable participant elements 116 in a bus system 110 comprising a control unit 112, a bus 114, and the addressable participant elements 116 connected to the bus comprises: a step a) of pre-selecting at least a first number (N1) of participant elements; a step b) of selecting a second number (N2) of participant elements from the pre-selected participant elements; and a step c) of assigning one or more addresses to them; and a step of repeating the steps a) to c). The selection and pre-selection are performed based on current sources CS1 and CS2, specific threshold values, and measurement error. The bus system 110 and an addressable device 116 are also claimed.
