Verfahren zum Betreiben eines Datenübertragungssystems

摘要

The invention concerns a process for operating a data transmission system with a plurality of stations (1, 2, 3, 4) connected to one another via a common bus line, only one subscriber (1) at any given time having right of access to the bus line and controlling data transmission over the bus line with polling messages (5) sent to several other stations (2, 3, 4) simultaneously. The response times (7, 8, 9) of the called stations (2, 3, 4) are determined. The called stations (2, 3, 4) are so parameterized that they acknowledge or answer the polling message (5) in order of their response times with reply messages (13, 14, 15). The invention is applicable to field buses in automation technology.
