PURPOSE: To accelerate fault processing by providing specified connection memories in respective parallelly connected cards, reporting fault generation to a diagnostic processor(DGP) at such a time and parallelly performing diagnostic control inside the cards corresponding to an instruction from the DGP for each card. CONSTITUTION: Respective CPU cards are composed of CPUs 2-1 to 2-4, system control parts 2-5 and diagnostic control parts 2-6 equipped with control memories 2-7 and the control memory 2-7 stores the respective routines of reset processing, initializing processing, constitution control processing, fault processing and diagnostic processing. When any fault is generated at the CPU inside the CPU card during ordinary operation, the fault processing routine in the control memory 2-7 is started and the generation of the fault is reported to a DGP 1-6. The DGP 1-6 discriminates the degree of that fault and outputs the instruction corresponding to this degree, and the control memory 2-7 parallelly performs diagnostic control inside the card for each card based on the instruction from the DGP 1-6. |
