Abstract

For a digital local communications system in the form of a bus with the logical structure of a loop in which the stations connected to terminal devices are in each case connected to a transmitting line and to a receiving line running in parallel with the former, with data flow directed in the same or in the opposite direction, and transmit their data as data packets provided with a priority flag, the stations feeding their data packets into the transmitting line only, and in which the data packets are transmitted at one point in the network from the transmitting line to the receiving line, it is proposed to allocate a request flag to each data packet in addition to the priority flag. The stations can feed their data packets into the transmitting line even if data packets with a lower priority than the priority of the data packet to be transmitted arrive on the transmitting line. In equal-priority incoming data packets, the request bit of the external data packet is set to "1" by the station wishing to transmit. If heavy data traffic occurs on the receiving line, the transmission protocol causes the data packets to pass through, extensively arranged according to priority, high-priority data packets can be transmitted immediately and access is provided to the data medium in the appropriate order with maximum utilisation of the transmission medium.
