Abstract

PURPOSE:To enhance the use efficiency of the control information transmission line, by using one control station as a root to constitute the control station and plural controlled stations with tree-form control information transmission lines. CONSTITUTION:In case that control information is transmitted from control station 21 to controlled stations 22-29, 210 and 211 to be controlled, control information where station identification codes peculiar to respective controlled stations are added to control contents for controlled stations requiring control are generated in control station 21, and all control information are transmitted in all directions. Each controlled station monitors always the station identification code in receiving control information; and if this information is control information for the station itself, control information is taken in, and control information is branched in directions other than the direction, from which control information is received from the control station, as it is. As a result, control information from the control station are transmitted to all stations to be controlled. Transmission of control information from stations to be controlled to the control station is performed similarly. For the purpose of realizing this system, buffer memories are provided in controlled stations which are repeating stations.
