Zusammenfassung: | PURPOSE:To reduce the kinds of testing devices required for a test and to simplify the constitution of a system inspecting system, by making possible the testing on the controlling program of a system contained in firmware which is operated by a controlling program having an information transmitting mechanism and the unit function of each device. CONSTITUTION:In the control card CCD of a system inspecting system, a peripheral device connecting section PIA which informs a microprocessor MPU of the set condition of a connection changing terminal KT is installed and a testing device TST 3 is connected with an input-output card ICD 2. Moreover, a microprogram for testing is additionally installed to an ROM in the card CCD and, when the terminal KT is set to the system inspecting condition, the testing device TST 3 is operated by the microprogram. Then an input-output card ICD 1 connected to the input-output card ICD 2 and input-output device IO is inspected under the control of a testing processor TPR. Thus testing on the unit function of each device is executed with fewer kinds of inspecting devices. |
