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.
