PURPOSE:To prevent the impact of signals on a bus, by assigning successively bus occupying right by using addresses in a bus transmission system. CONSTITUTION:In a frame transmitted from each terminal, normal data are transmitted from SA (sending address) to DA (destination address) by F (frame pattern), DA, SA, C (control signal), DATA (data), and CRC2 (check code) parts. TA is an address of a station to occupy a transmission line subsequently, and CRC1 is a check code for the TA. Each station monitors the TA always, and when a frame including the TA for the self-station is transmitted, transmits the transmission data of the self-station on a bus after completing said frame. |
