The relationship between the failure module number and the affected module affected by the failure module number is described in the failure influence point detection database D4, and the module for which 1 is set in the table is affected by the failure module. It means that a module set to 0 is not affected by the faulty module.

In FIG. 10, the failure influence state storage table T4 indicates whether or not each module is affected by a certain failure, and if it is affected, the value 1 is set. If the state is restored from the influence, it is indicated by setting 0.

When it is determined that the module pair is affected by the failure, the module is determined to be affected by setting 1 to the corresponding module in the failure effect state storage table T4 shown in FIG. 10 (step 89).

On the other hand, if the counterpart module to be paired with is not affected, the affected module is set to 0 in the failure influence state storage table T4 to eliminate the influence (step 90).

Further, as a result of the operation of step 86, the failure influence state storage table T4 is also determined when it is determined that the influence is not exerted.
By setting 0 in the corresponding module of No., there is no influence (steps 87, 90).

5) If it is an affected line, the variable i is used as a key to open the failure state storage table T2 described above (step 126). If the module of the variable i is in failure, then FIG. Substitute 1 indicating that there is a line affected by the failure in the column corresponding to that line in the affected line detection state storage table TL4 shown (step 127). On the other hand, the failure state storage table T2 is pulled (step 126), and if the module of the variable i is not in failure, the variable i is used as a key to pull the failure influence state storage table T4 (step 128),
If the module of the variable i indicates the affected module, the column 1 corresponding to that line in the affected line detection state storage table TL4 shown in FIG. Substitute (step 129). If the module corresponding to the line variable i has no failure and is not affected by the failure of another module, the column corresponding to that line in the affected line detection state storage table TL4 is not a line affected by the failure. Is assigned to 0 (step 1
26, 127, 128).

The above processing is repeated for all the modules and lines (steps 131 and 132).

The fault output processing units 3a and 3b change the color of the line affected by the fault based on the affected line detection state storage table TL4 and display it graphically as shown in FIG.
