ABSTRACT:
To determine the network topology of a bus system having a number of bus users positioned on bus segments of a bus line interconnected by at least one diagnosis repeater, an initiating measuring telegram is first sent to each bus user. This telegram is answered by the diagnosis repeater with a data telegram having a segment code and by other bus users with a response telegram. The diagnosis repeater then sends a measuring signal to each responding bus user, which reflects the signal. The distance of the responding bus user from the diagnosis repeater is determined from the time interval between the sending of the measuring signal and the arrival of the reflection signal.
