Abstract

PURPOSE:To improve the protectiveness and reliability of the whole device without doubling a computer for transmission, by providing a subordinate computer with the functions of the computer for transmission when a host computer discriminates the fault of the computer for transmission. CONSTITUTION:When a host computer 1 judges that a subordinate computer 5A for transmission is abnormal, a device which is less influenced by a shutdown between intelligent computers 8 and 11 which are functioning so far, e.g. 11 is provided with transmitting functions. This is called a substitute computer 11. The computer 5A for transmission when having normal communication with the subordinate computer and R/S stations 13-16 while only the host computer is disabled confirms the stop of the computer for transmission, and starts signal transmission. On the other than, the computer for transmission confirms that the substitute computer 11 is switched to the one for transmission, and stop the transmitting functions. When the computer 5A for transmission becomes normal, the substitute equipment 11 is recovered.
