Abstract

PURPOSE:To detect a fault position rapidly and accurately by judging accurately which equipment is in trouble by diagnosing the fault of the fault by diagnostic steps of an input-output device or computer. CONSTITUTION:To the closed-loop transmission line, many transmission-line communication device 3 are connected and devices 3 send data and clocks to transmission lines 1 and 2 and also regenerate signals from transmission lines 1 and 2 into data and clocks, thereby performing the conversion of data and the transmission of information according to prescribed programs. Devices 3, and computers 8 and 9 and terminal controller 7 are connected together via bus 4 and computer interfaces 5 and 6 and input-output terminal devices 13 and 14 are connected to interfaces 11 and 12. From either one of devices 13 and 14, diagnostic information in the predetermined format is inputted and decoded by device 7 to generate the diagnostic instruction and diagnostic data and the fault is diagnosed by diagnostic steps of devices 13 and 14 or computers 8 and 9 to quicken the detection of the fault position.
