Firmware update method
■Preliminary preparations
1. Download the firmware update information for the model to be updated from the Mitsubishi Electric FA website.
2. Decompress the firmware update information (ZIP file).
3. Store the "$MELPRJ$" folder containing the firmware update file and Web page update file into a desired folder.
4. Connect the engineering tool to the CPU module.
5. Stop the CPU module and system for which the firmware update function is to be executed. Turn off the power to other
systems and devices connected to the CPU module. If the power cannot be turned off, disconnect communication
cables.
6. Check that no other function is executed on the CPU module.
7. Check that no file operations such as writing to the programmable controller, online change, and file transfer function are
executed. (If the update is started with a file operation being executed, the operated file may be damaged.)
8. If updating of the firmware is prohibited, cancel the prohibit setting. (Page 97 Canceling the firmware update
prohibited setting)
9. Check that no stop errors have occurred on the CPU module.
10. Before executing the firmware update, back up the various data such as the programs and parameters stored in the CPU
module by using the engineering tool. Also, use the backup/restoration function to hold latch devices. (Page 207
