PURPOSE:To minutely segment the fault of a station and to easily specify the fault part of the station by giving microprocessors independent of the station which is the dignosis object. CONSTITUTION:Diagnostic devices 40 and 50 are provided with interface parts 41 and 51 which realize interfaces with the stations 10 and 20 and connect the stations 10 and 20 with the diagnostic devices 40 and 50, and external controllers 42 and 52 which have the microprocessors and diagnoze the online of the stations 10 and 20. Since the devices 40 and 50 executing diagnosis processing and the stations 10 and 20 becoming the diagnosis objects can independently be operated by the different microprocessors, the diagnostic devices can execute a diagnosis program at the spare time of the transaction processing of the station even when the station being the diagnosis object is in the middle of executing an online processing. |
