Feedback welcome (broken links, improvements or additions needed).
Note - M580S V3.20 FW is are not yet available. Expected later this month.
The new EcoStruxure Automation Device Maintenance (EADM) tool is now available (link in the spreadsheet). At the moment there is no cloud connectivity for firmware updates so the spreadsheet is still a useful source. Follow the instructions to place the FW files into the correct location for EADM to use.
EADM is mandatory for BMENUA and BMENOR module FW upgrades.
