PURPOSE:To attain a processor status monitoring means by means of software and to miniaturize the monitoring means by allowing a monitoring program part to monitor the operation ending status of control program in respective functions. CONSTITUTION:This power supply controller 2 controls a power supply device 3 in the monitoring/control of a master controller 1. When the controller 2 detects abnormality such as a runaway state, monitoring program part 5 executes a monitoring program for informing the fault of the device to the controller 1. Thus the program part 5 monitors the operation ending state of a control program 4 for respective functions such as power ON/OFF and power supply abnormality processing to be started at the time-up of a monitoring program timer (not shown). Consequently a processor status monitoring means for the power supply control device 2 can be attained by means of software and hardware can be reduced and miniaturized by functioning the system. |
