Abstract

PURPOSE:To log out information at the time of a trouble without providing a memory or the like for saving its internal information of a subprocessor, by actuating a trouble processing circuit in a subprocessor when a central processor detects a trouble related to the specified subprocessor, and freezing the trouble as that detected by the subprocessor within its own device. CONSTITUTION:In an electronic device that applies centralized control for plural input/output channel devices 4 with a channel controller 3, while a CPU1 is transferring data in a specified channel devices 4 to the controller 3, if the controller 3 detects 6 a parity error, a main control part 7 sets an error check latch 10 in the devices 4. The output of the latch 10 is ORed with the output of a error check latch 11 that is set when the devices 4 detect a trouble in its own device, is inputted to a main control part 8 and an input/output control part 9. The control part 8 freezes the operation of the devices 4 and the control part 9 freezes the operation of an input/output device 12, respectively, an output 16 is outputted to the controller 3 as a trouble reporting signal.
