tions Board or Serial Communications Unit together with the time that the
error occurred.

RAM Error Log Table 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.

restarted. The contents of the EEPROM error log table is automatically read

in the EEPROM error log table for each error that occurs for up to 32 errors
max.
