displayed according to the values set in the Config.
SD additional features mode
If you press the SD CMD button once for more than 0.7 second and less than 2 seconds, the flag (%KX8640) will be
turned On and the PLC update operation will be executed while the SD RD/WR LED and SD additional features are
running.
When the update is completed normally, the flag (%KX8640) is turned Off and the completion flag of SD additional
features (%KX8642) is turned On while the SD RD/WR LED and SD additional features are running.
If an error occurs during operation, the SD additional function error flag (%KX8641) is turned On and the error value
is displayed in the SD additional function error code (%KW542).
(1) When ‘Read-protected from PLC’ is set, even if the update process is normal, reading from the PLC via
XG5000 is prohibited. If the PLC password option is set and the password has not been set in the PLC, the
password will be saved to the PLC along with the project update. In addition, if the password is already set in the
PLC before performing the project update using the SD, the update will be executed only when the password set
as the option matches the password of the PLC.
(2) If ‘Limit PLC usage’ option is set, the PLC update is performed only when the MAC address stored as the
option matches the MAC address of the PLC.
(3) If auto-reset is set after update is completed, the PLC will be reset automatically after updating is done, and the
PLC operation mode will be changed into the PLC status option specified value.
