    摘要: In order to register the order of bus subscribers (12) when starting a system without the use of a token line to be specifically laid for his purpose along the two-wire bus (11), the bus master (13) temporarily activates a reflective discontinuity, preferably a bus short circuit, in a respective selectively addressed one of the subscribers (12) after stochastically determining all subscriber addresses (Ki). The echo signal (19) of a voltage jump (18), which is then output onto the bus (11) by the master (13), is superimposed in the master (13) to form a square-wave-like differential signal (20) whose pulse duration which is proportional to the distance between the master (13) and that subscriber (12) along the bus (11) is measured following pulse shaping by analog pulse area integration (25).
