Abstract
The invention relates to a method for detecting the position of a bus subscriber (2, 2a, 2b, 2n) of a bus system, in which a control device (1) and several bus subscribers (2, 2a, 2b, 2n) are provided. The bus subscribers (2, 2a, 2b, 2n) are respectively in a position (P1, P2, Pn) to be detected and are connected to the control device (1) via at least one line, the line to the respective bus subscriber (2, 2a, 2b, 2n) having a definable line length (L1, L2, Ln), and the position of a bus subscriber (2, 2a, 2b, 2n) is then detected. The control device (1) emits a signal by means of an oscillator (3) via the line to the respective bus subscriber (2, 2a, 2b, 2n) and the bus subscriber (2, 2a, 2b, 2n) responds. The frequency of the oscillator (3) is determined and a ratio of frequency and line length (L1, L2, Ln) is used to detect the position.
