Abstract

PURPOSE: To increase the overall reliability of system, by providing the multiplexer between a plurality of master stations forming the data way and the electronic computer and by giving the back up function if the master station is in failure.
CONSTITUTION: A plurality of remote stations 6 are connected with coaxial or twist pair cable 5, and a plurality of master stations 41 and 42 controlling the station 6 are provided, and the multiplexer 7 which can connect only one station to the computer 1 is connected between the stations 41 and 42 and the electronic computer 1 via the direct memory access channel 2. Further, if the station 41 or 42 is in failure, selection signal is fed from the computer 1 to the multiplexer 7 and the data way is kept to normal operating condiction by selecting the failed stations 41 or 42 to normal station 42 or 41.
