Firmware Updates are accomplished on the m340 and m580 via a tool called Unity Loader. At the time of writing this, the latest version of Unity Loader is V12.0 . Schneider provides an ISO file on their website which is a disk image file. For more information on mounting an ISO image, see this link.

Connect to the 5 pin USB mini B port with either a BMXXCAUSBH018 (1.8m) or BMXXCAUSBH045 (4.5m). Go to the Schneider Electric website and do a search for the CPU you intend to update. Look for a listing in the search results with a “SV#.##”. Download and save the *.7z (7z is a type of compressed zip file) file
to your local hard drive.
