Precautions
• Check the target model, and download the correct firmware update file from the Mitsubishi Electric FA website. The
firmware will not be updated if the target model does not match.
• Do not change the data (folder and file name) downloaded from the Mitsubishi Electric FA website.
• Before executing the firmware update, enable the CPU module reset setting. (Page 127 Enabling remote RESET) If
the update without enabling the reset setting was performed, do not turn the CPU module power OFF and ON or reset the
module, and re-execute the update after enabling the reset setting.
• Update the firmware after confirming that the intelligent function module to be updated is normally running.
• Update the firmware after confirming that the function using the intelligent function module and SD memory card has
stopped.
• Update the firmware after confirming that other systems connected on the network have stopped. Communication with
other systems may be stopped.
• Back up the various data such as the programs and parameters before executing the firmware update.
• Do not turn the power OFF or reset the CPU module while the firmware update is in progress.
• Do not remove the SD memory card while the firmware update is in progress. If the SD memory card is removed before the
firmware update finishes, the process may end with an error.
• If the automatic reset is disabled, manually turn the power OFF and ON after the completion of the update.
• If the system malfunctions after the completion of the firmware update, downgrade the firmware to the previous version. If
your version is not found on the Mitsubishi Electric FA website, please consult your local Mitsubishi representative.
• If any of the following operations is performed during the period from the start to the end of the firmware update, the
firmware update may complete with an error, or the module may be damaged.
- Turning OFF the power to the system under firmware update, or resetting the system
- Remotely operating from the engineering tool, or changing the operation status with the CPU module switch
- Removing the SD memory card
- Operating the system under firmware update from an external device
- Connecting/disconnecting the communication cable connecting the CPU module and engineering tool
- Connecting/disconnecting the module under firmware update
- Operating the engineering tool to start the firmware update
- Stopping the engineering tool
