Abstract

PURPOSE: To secure the clear isolation between the fault of the system side and the fault of the support device side, by incorporating the processor PC, self-diagnosis firmware FW and the clock generating circuit each into the system support device.
CONSTITUTION: System support device 2 includes RAM12 which stores the program or the data, control memory 13 which stores the console function and the self- diagnosis FW, and local PC15 which carries out the control within device 2 or for the system 1 side based on the program stored in memory 13. Furthermore, the following parts are provided to device 2: various function control part 16 which includes the mode switch to select the working of the CPU at the system side or PC15, the memory switch to select the memory at the system side or the device side, and others; and clock generator 17 which is necessary for the single working of PC15. As a result, the clear isolation is possible between the fault of the system side and the fault of the support device side in case the system fault is detected, thus increasing the reliability.
