PURPOSE:To eliminate the necessity of interface between each processor and a diagnostic processor and collect fault information from each processor without destruction by providing a gate between a system controller and each processor and diagnostic processor. CONSTITUTION:Transmitting registers 22 and 23 which hold transmitting information to each processor 6-1 and 6-2 and receiving registers 32 and 33 which hold information received from the processors 6-1 and 6-2, are installed to a system controller. Moreover, a diagnosis control register 21 which holds diagnostic information from a diagnostic processor 4 and a fault information receiving register 31 which holds the fault information of the processors 6-1 and 6-2 are also provided. Furthermore, gates 101-108 which are selectively connected with the interfaces 71-74 between each register 22, 23, 32, 33, and 31 and the processors 6-1 and 6-2 are also provided. In addition to the above, gates 109-112 and 113- 116 which are selectively connected with the interfaces 71-74 are installed to each processor 6-1 and 6-2, respectively. In such a way, the necessity of any interfaces between each processor 6-1 and 6-2 and diagnostic processor 4 is eliminated and the diagnostic information is collected without destruction. |
