Abstract

PURPOSE:To hold an inspection time unchanged even if the number of stations increases, by providing each station with a function of switching two transmission lines and that of inputting and outputting data from and to both left and right stations. CONSTITUTION:When a looped data way is actuated or troubled, the transfer of signals that a monitoring station 1 sends to independent stations 2, 3, 4... is stopped, so that each station is initialized. Then, the stations 2, 3, 4..., each provided with a function of alternating two transmission lines and that of inputting and outputting data from and to either adjacent station, checks the states of adjacent stations through data interchange on the basis of instructions from the station 1. Consequently, an inspection time in the actuation or fault occurrence of the system is shortened and kept constant without reference to the number of stations.
