Abstract
PURPOSE:To prevent disorder of a system in the event of instantanous service interruption, by providing an electric power source separately from an electric power source of an input/output controller, also monitoring the control sequence of the electric power source of the input/output controller, and executing the electric power supply to a storage part from the independent electric power source part in accordance with whether said control sequence is normal or not. CONSTITUTION:An emergency electric power source 8 is connected to an electric power soure V through a relay 9 closed by a READY signal for instructing a start operation when an auxiliary storage device is operated, also closes a relay 10, and connects the electric power source 8 to controllers 3, 4 and a channel. Subsequently, the relay 10 releases a contact of a relay 11 by a NORMAL OFF signal transmitted when the electric power source has been disconnected, and its self-holding is released. In case when the electric power source of the input/output controller is off, the READY signal and a POWER- ON signal are turned off simultaneously, and the NORMAL-OFF signal is not transmitted either. Accordingly, since the relay 10 continues its self-holding at an abnormal time, the electric power supply to the controllers 3, 4 from the electric power source 8 is continued as it is.
