METHOD FOR OPERATING A RADIO COMMUNICATION SYSTEM FOR AN INDUSTRIAL AUTOMATION SYSTEM, RADIO COMMUNICATION SYSTEM, BASE STATION AND SUBSCRIBER STATION

摘要

In order to operate a radio communication system for an industrial automation system, which comprises at least one base station (100) and a plurality of subscriber stations (101-103), at predefined transmission times (t_P.N) the base station cyclically polls datagrams (20) to be transmitted by the subscriber stations. Within a polling cycle, the base station predefines for the subscriber stations the transmission times (t_P.N) for transmitting the datagrams to be transmitted. In the process, the transmission times (t_P.N) are each determined from a preceding transmission time (t_P.N-1) by adding a polling cycle duration (t_C) and subtracting a delay time (t_W.M), while the at least one datagram to be transmitted prior to the preceding transmission time is already in the corresponding subscriber station and ready for transmission. The subscriber stations transmit information to the base station regarding the corresponding delay time in order to determine the transmission times.
