The present invention aims at obtaining a fault-tolerant system of low cost and high reliability which system permits a smooth change-over of processing in the event of occurrence of a fault. The fault-tolerant system is provided with a plurality of processors each having a program area and a data area in which is set information indicating a portion of an input/output section required in the program in the program area, and is also provided with a control station for controlling those processors. Upon detection of a non-executable state of a module in a certain processor, the control station supplies to another processor the program in that module as well as information which indicates a required portion of the input/output section, and instructs the another processor to continue the execution of that module. <IMAGE> |
