Abstract

PURPOSE:To eliminate the limitation to the connecting position of a control station, by giving the priority to a group of each transmission station separated into left and right of the control station. CONSTITUTION:Various information devices IDi scattered in a factory are coupled into one transmission line L via a transmission station STi, and a control station CST monitors and controls the transmission start and the transmission state of entire network to each transmission station. By taking the station CST as the base, each station STi is divided into two groups; one is connected to left transmission lines and another is connected to right transmission lines. Two types of transmission start signals representing that the higher transmission priority is given corresponding to each group are provided, and the station CST changes the rate of transmission of the start signal according to the number of times of transmission request of both the groups.
