Therefore, since the range of self-diagnosis is expanded and the period of self-diagnosis can be shortened, the effect of improving the safety level can be obtained. [Embodiment] (First Embodiment) Hereinafter, a f 4 322037 201122745 conformation of the dual system control device of the present invention will be described with reference to the drawings. Fig. 1 is a schematic configuration diagram of a dual system control device in a first embodiment of the dual system control device of the present invention. In the figure, the dual system control device is constructed by dualizing the human system for the control system and the B system for the other control system. Each of the control systems a&b has a cpu (emeral processing unit) for performing arithmetic processing and the like, 1B, memory 2A, 2B connected to the cpus, and is connected to each CPU, and is controlled by the control object. The input information is transmitted to the input control units 3A, 3B of these CPUs, and the output control units 4A, 4B that control the output information output to the output control device 7. The input control units 3A and 3B and the output control units 4A and 4B are connected to the switching device 5 that performs system switching by the system switching finger signal, whereby the output information of any of the A system or the B system is passed through the output device. The output is output to an unillustrated control object, and the input information from the control object is input to any of the a system or the B system via the input device 6. Next, the operation of the dual system control device will be described. Fig. 2 is a conceptual view showing the operation of the first embodiment of the dual system control device of the present invention. In Fig. 2, for the sake of convenience, the system is considered to be the actual control system at the start of the time series (hereinafter, referred to as the actual control system j', and the B system is regarded as the self at the beginning of the time series. The system for diagnosis (hereinafter referred to as the self-diagnosis system) performs the actual control or self-diagnosis, respectively. As shown in Fig. 2, in the first embodiment, the switching of the two: is performed at the same time. The figure shows in detail the flow chart of the operation of the two systems.

Control The system is described as a self-diagnosis system at the beginning of the B system. When the A system performs a series of controls as the actual control system (S01), the B system performs self-diagnosis as a self-diagnosis system (S03). When the system confirms the end of the self-diagnosis of its own system (S05), it sends a system switching instruction (S06) to perform system switching (S02 and S04). On the other hand, it is confirmed by the A system of the actual control system. When the system is switched (S07), the switching is performed (S02 and S04), the A system starts self-diagnosis as the self-diagnosis system (S03), and the B system starts the actual control as the actual control system (S01). The actual control system and the self-diagnosis system are interactively switched, and the A and B systems perform self-diagnosis interactively, thereby realizing self-diagnosis of the main memory such as the main memory that can be performed offline only in the overall operation of the system. Therefore, since the range of self-diagnosis is expanded and the period of self-diagnosis can be shortened, the effect of improving the safety level can be obtained.
