Abstract

PURPOSE:To prevent the program complication and at the same time to increase the input/output processing speed, by storing the number of a defective input/ output channel into a channel number storing means to compare this number with another input/output channel number whose start is designated. CONSTITUTION:When an input/output channel 4, for example, has a defect while an input/output processor 3 is working, the number of the channel 4 is temporarily stored in a channel number storing means (register 8). Then the start of the channel 4 is instructed again, an input/output channel number comparing means (comparator 9) compares a designated input/output channel number with the stored one. When the coincidence is obtained between both channels, a substitute channel 10 is selected and the channel 4 is separated. Thus the data are transferred between a main memory 2 and an input/output device 6 via the channel 10 in place of the channel 4.
