PURPOSE:To simplify the constitution of a power supply controller by deciding a service processor that records the information on a power supply fault based on the received operating state. CONSTITUTION:Both service processors 40 and 50 are connected to the logic devices 10 and 20 via diagnosis interfaces respectively. In a contact connecting operation mode one of these processors is valid and diagnoses both devices 10 and 20. While both processors 40 and 50 diagnose both devices 10 and 20 in a separating operation mode. A power supply controller 60 monitors the overall state of the device power supply via a serial control bus 85 and contains a power supply abnormality information collecting part 63 which collects the power supply abnormality information on plural devices and a power supply abnormality information transmitting part 62 which transmits the power supply abnormality information to the processors. Each of both processors 40 and 50 contains an operation recognizing part 43 which recognizes the present operating state, a power supply abnormality information receiving part 44 which receives the power supply abnormality information from the controller 60, and a power supply abnormality information selecting part 45 which selects the power supply abnormality information based on the operating state. |
