Abstract

PURPOSE:To simplify a wiring form so as to make it into one system of a loop form, and, at the same time, to reduce the burden of maintenance and inspection by forming a loop-form transmission line by connecting a master station and a plurality of subsidiary stations in series by means of an optical fiber. CONSTITUTION:A general-purpose programmable controller 1 outputs an on/off signal for the load control to a master station 3 in accordance with a sequence programmed in advance by a program loader 2. A plurality of subsidiary stations 4 are provided in the vicinity of motor, heater, solenoid valve, etc., to handle their plurality of loads, and the interstation connection between the master station and each subsidiary station is made in series by an optical fiber 5 so that each subsidiary station fills the role of a signal translator for the station next to it.
