Precautions
• Back up the various data such as the programs and parameters before executing the firmware update.
• 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.
• Do not turn the power OFF or reset the CPU module while the firmware update is in progress. Doing so may cause
programs to be deleted.

depending on the serial No. For details on operation, refer to Page 478 Added and Enhanced Functions.
