PURPOSE:To make it possible to collect the status of a system at the detection of the abnormality of a central controller by informing the detection of the abnormality of another processor and holding the system status at the detection so as to be read out. CONSTITUTION:The central controller 1 is connected to an emergency control circuit 2 through an operational abnormality detecting signal 4, a stop request signal 5 and a rise request signal 8, the circuit 2 is connected to a maintenance control device 3 through an operational abnormality informing signal 6 and the devices 1, 3 are connected through a system status reading bus 7. When the device 1 detects abnormality, the signal 4 starts the circuit 2 and the circuit 2 makes the circuit 1 hold at its system status by the signal 5 and commands the device 3 to read out said system status through a signal 6. The device 3 reads out the system status of the device 1 through a bus 7, and during the reading, the circuit 2 is held at timing waiting status. After completing the reading, the device 1 is raised by the signal 8.
