Note
The settings in the Setup Area are reflected here. The default settings will be
used and will be stored here if a setup error occurs.
Error Log EEPROM Error
This bit will be set to 1 if an error occurs in reading or writing the error log
stored in EEPROM on the assumption that the EEPROM has reached its use-
ful life. If a Serial Communications Unit is being used, the ERC indicator will
also light. If a Serial Communications Board is being used, A42411 will turn
ON and the ERR/ALM indicator on the CPU Unit will flash, indicating a non-
fatal error.
Protocol Data Error
This bit will be turned ON if a checksum error is detected in the protocol data
at startup. The checksum is checked for all serial communications modes. If a
Serial Communications Unit is being used, the ERC indicator will also flash. If
a Serial Communications Board is being used, A42409 will turn ON, the ERR/
ALM indicator on the CPU Unit will flash, and the RDY indicator will flash at 1-
second intervals, indicating a non-fatal error.
