PPROBLEM TO BE SOLVED: To automatically restart program processing even if an error occurs in the program processing when powered on. PSOLUTION: A CPU chip set control IO 12 issues instructions to a CPU in a CPU chip set 11 to execute hardware reset processing, and starts timer operation of WDT 14 when power is turned on or when a rest signal is input from the WDT 14. The CPU in the CPU chip set 11 stops the timer operation of the WDT 14 when start processing normally ends. PCOPYRIGHT: (C)2011,JPO&INPIT
