11-4-2 Error Log Specifications

The error log function records the errors detected in the Serial Communica-
tions Board or Serial Communications Unit together with the time that the
error occurred.
For every error that occurs, one record is logged in the RAM error log table in
the Board or Unit for up to 64 errors.
Records of errors that are particularly serious are logged in both the RAM
error log table and the EEPROM error log table in the Board or Unit when they
occur. The contents of errors logged in the EEPROM error log table remain
even if the power to the Board or Unit is turned OFF or the Board or Unit is
restarted. The contents of the EEPROM error log table is automatically read
to the RAM error log table when the power is turned ON. One record is logged
in the EEPROM error log table for each error that occurs for up to 32 errors
max.
