PURPOSE:To spot ill states in functions and operations always checking the safety in functions and operations beforehand, by making an information processor itself control the power source to be supplied thereto with execution of instructions by itself to implement a voltage margin testing automatically and periodically. CONSTITUTION:A processor 3 triggers a program to execute input/output instructions for the control of the power source and changes the output of a power source unit 2 to a level higher 10% than the rated value. Then, a test program is executed for the processor 3 and input/output controllers to implement a voltage margin testing. |
