Abstract

PURPOSE: To prevent the system function from being lowered at computer failure, by providing the auxiliary memory storing the content of the main memory of the control computer and the computer monitoring the condition of operation of computer, in the process control system of multi-constitution.
CONSTITUTION: The process control computers COMP-1...COMP-N... control the specified process P. The COMP-B is a back up computer, which monitors the working condition of COMP-1... . From the content of the main memory of each process control computer, the image required for the operating condidion required for leading of the back up operation especially is memorized in the auxiliary memory SM. When the back up computer COMP-B recognizes the occurrence of failure in either of the process control computers, the input and output to the process P of the computer is selected to COMP-B side, from the auxiliary memory SM, the operation image required for the function image of the failed computer and leading is loaded, the function of the failed computer is substituted, thereby preventing the function of the overall system from being lowered.
