PURPOSE:To automatically conduct the test at night or in unattended state by loading a program acting a standby system computer as a data recorder or a program simultating an equipment to be controlled to the standby system computer and using the program to automatically execute the test of a control system computer. CONSTITUTION:The program functioning the standby system computer as a data recorder or a program simultating a device to be controlled by a standby redundancy controller is loaded in the standby system computer 22 and the test of the control system computer is executed automatically by the programs. That is, with an interlock 42 closed, a converter and its scanner are inserted between a process input/output device of the standby system computer 22 and a converter used for the actual control such as a current/voltage converter 24. That is, a voltage/resistor converter 43 converts a voltage signal outputted by an analog output card 20 of the standby system computer 22 into a resistance signal and inserted between the interlock 42 connected to the output card 20 and a resistance/voltage converter 25 together with the scanner 44. |
