9. Turn the CPU module power OFF and remove the SD memory card. Delete the firmware update file from the removed
SD memory card.
*1 The waiting time is as follows.
 FX5S CPU module: Up to 70 seconds
 FX5UJ CPU module: Up to 120 seconds
 FX5U/FX5UC CPU module: Up to 90 seconds
*2 The waiting time is as follows.
 FX5S CPU module: Up to 60 seconds
 FX5UJ/FX5U/FX5UC CPU module: Up to 45 seconds
*3 The waiting time is as follows.
 FX5S CPU module: Up to 30 seconds
 FX5UJ CPU module: Up to 90 seconds
 FX5U/FX5UC CPU module: Up to 90 seconds
*4 For the FX5U/FX5UC CPU modules, this operation is required when the firmware version is "1.045" and later.
• Communication with other modules and communication with the engineering tool or external devices is not
possible while the firmware update is being executed.
• During firmware update, the data memory will be backed up
*5
to the SD memory card.
* 7
• If the firmware is updated correctly, the data memory will be restored
*5
from the SD memory card to the
CPU built-in memory.
* 7
After the data memory is restored, the data memory backup file in the SD memory
card will be deleted.
• If the data memory fails to be restored, restart or reset the CPU module, and a recovery retry
*6
will be
executed.
* 7
While the data memory is being restored by recovery retry, the RUN LED and ERR LED blink
slowly (five seconds or more). The LED will turn OFF when the file is correctly recovered. If the recovery
fails again, the ERR LED will blink.
• The firmware version can also be confirmed with the special register (SD8001).
• After the firmware is updated, if a firmware update file that differs from the CPU module's firmware version is
stored in the "$MELPRJ$" folder of the SD memory card, the firmware will be updated.
*5 Refer to Page 942 Added and Enhanced Functions for the versions that support data memory save/recovery of FX5U/FX5UC CPU
module.
*6 Refer to Page 942 Added and Enhanced Functions for the versions that support data memory recovery retry of FX5U/FX5UC CPU
module.
*7 For the FX5S CPU module, the firmware update can be executed without save/recovery, no save/recovery is executed.
