PURPOSE:To attain an integrated fault processing system by having the sequence discontinuation control when a fault is detected during the data transfer to set a queuing state for reset of data transfer and informing the generation of the fault to attain the retransfer of data. CONSTITUTION:When an A system fault detecting part 2 detects a fault, a fault detecting signal is sent to a fault processing part 5. Then a control signal for sequence interruption is sent to a sequence interruption control part 6. The part 6 give the control so that a transmission sequence under execution is interrupted to sequence control parts 1 and 3 of A and B systems respectively. Then a fault informing signal is sent to a central processor A from a fault informing part 7 with an indication of the part 5. While the processor A transmits a transmission preparatory request signal to an input/output controller C to perform the retransfer of data. |
