PURPOSE:To reduce the load of an operator with a system power supply control system of an electronic computer by cancelling the alarm display of a service processor device after detecting the cancel of an alarm. CONSTITUTION:The alarm state ''1'' of the state signal of a certain device is cancelled, and the state signal is set at ''0''. Then an alarm cancel detecting circuit 15 differentiates a fact that the state signal is changed to 0 from 1 to produce an alarm cancel signal and supplies with interruption this signal to a service processor device 2. Receiving this interruption input, the device 2 confirms again that the alarm latch of an alarm latch circuit 12 of a system power supply controller 1 is cancelled automatically by the prescribed sequence and then cancels the alarm display of the device 2. |
