Internode Test Section 9-3
9-3-2 Checking Results
The results of the internode test are stored in the fourth through ninth words of
the portion of the CPU Bus Unit Area allocated to the FL-net Unit. The status
information area stores the test status and numbers of test runs and errors.
Test Status
The result of the test run and descriptions of errors are stored as the test sta-
tus. The test status is stored at the word whose address is calculated by the
following formula:
Stored words = 1,500 + (25
×
unit number) + 3
Error Code If the test is run repeatedly, the code for the latest test results is stored.
Error Flags The bits corresponding to errors are turned ON if errors occur. The flag status
is maintained until the internode test is run again.
Number of Test Runs and Errors
The number of test runs and total errors from the time the test is started until it
is stopped is stored. The configuration of this area is shown in the following
table. Each result is stored at a word relative to the first word the address of
which can be calculated using the following formula:
Stored words = 1500 + (25
×
unit number) + 3 to +5

Note 1. The contents of the test status area and test runs/errors area are main-
tained until the internode test is run again.
2. When the number of tests counts to the maximum value (FF Hex), subse-
quent internode test runs are counted from 0. However, the maximum val-
ue is maintained and further errors are not counted when the number of
errors reaches the maximum value.
