Abstract

PURPOSE: To enable to diagnose the input and output control unit with separated I/O unit or under operation of I/O as required, by mounting the memory unit for diagnosis.
CONSTITUTION: On the diagnosis memory unit 7 of the input and output control unit 1, the diagnostic dada having the information format corresponding to the memory data recorded to the I/O unit 2 is stored, and if only the diagnosis to the read processing is made, the data having the same format as the said diagnostic data is stored on ROM of the unit 7. Next, at the diagnostic mode, the diagnosis mode instruction is given to the multiplexer 5, the content of ROM is sequentially read, and this read data is transferred to the data separation circuit 4 as if this read data were those read from the unit 2. Since the content of ROM is known in advance, the diagnosis is easily enabled and also diagnosis can be made by writing the data on RAM of the unit 7.
