Abstract

PURPOSE: To increase the reliabiltity of system, by providing the electric isolation circuit and the multiplexer between a plurality of master stations forming the data way and the electronic computer and by selecting the master station in failure without hindrance.
CONSTITUTION: A plurality of remote stations 6 forming the data way is connected with coaxial or twist pair cable 5, a pulrality of master stations 41 and 42 controlling the station 6 are provided, and the electric isolation circuits 81 and 82 are connected to the stations 41 and 42 with the cables 31 and 32. Further, the multiplexer 7 is connected to the isolation circuits 81, 82, and the multiplexer 7 is connected to the electronic computer 1 via the direct memory access channel 2 by the cable 3. Further, the function connecting only one of the stations 41, 42 to the computer 1 is given to the multiplexer 7 and if one of the stations 41, 42 is in failure, change-over is made from one to antother by change-over signal of the computer 1.
