Abstract

PURPOSE: To enable the diagnosis of function without lowering the effect of system, by checking the functions of the input and output circuit based on the check data fed from the computer through the use of vacant time of transferred data.
CONSTITUTION: When the transfer data is fed to the input and output circuit 13 from the peripheral unit 12, the gate signal is outputted to the gate circuit 20 from the detection circuit 28 with a given time delay than the leading of the transfer data. On the other hand, the transfer data serial fed from the peripheral unit 12 is fed to the serial parallel conversion circuit 22 and converted into parallel data. At this time point, when interruption is made from the circuit 13 to the computer 11, the check data is fed from the computer 11 to the register 19. This check data is read out at the gate 20 and stored in the register 25 after conversion into parallel data at the circuit 22. Further, it is compared with the check data of the register 24, and if the content of the registers 24 and 25 is in disagreement, error signal is delivered from the control circuit.
