Abstract
PURPOSE:To reduce failures caused by unknown causes in a data processing system, by confirming the simultaneity between the operation of a voltage failure detector and the malfunction in a processor, in a monitor device. CONSTITUTION:An AC voltage on an external AC input power supply 22 and a DC voltage on a DC input power supply line 23 are monitored with voltage failure detectors 7, 8 and 9, 10. If the AC input voltage is not within a specified value, the corresponding voltage failure detectors 7 and 8 detect it and output a voltage failure signal to set latches 11 and 12. If the DC input voltage value is not within a specified value, the corresponding voltage failure detectors 9 and 10 detect it to set latches 13 and 14. If the latches 11, 12 and 13, 14 are set, an interrupting signal generating circuit 18 or 19 is started, and the interrupting signal is transmitted to an interruption signal reception section 19 of a monitor device 2.
