Errors are recorded in an error log table in the Board's RAM, with one record for
each error and a maximum of 39 records.
Serious errors are also recorded in the Board's EEPROM so that when the pow-
er to the Board is turned OFF or reset, a record of the error will remain. (The error
log table in EEPROM automatically reads the Board's RAM when the power is
turned ON again.)

Error code
The time is recorded in BCD with one byte each for the year (the rightmost two
digits), month, day, hour, seconds, and minutes of the time the error occurred.
Note The computer's time information can be read and used in the Controller Link
Support Board. When the time cannot be read from the computer, all error log
times will be 0. When error logs are read from the Controller Link Support Soft-
ware, they will be dated 0 s, 0 min, 0 hr, 0 day, 0 month, 2000.
The following table lists the error codes (in 4-digit hexadecimal) and the contents
of the errors.
