Beckhoff EtherCAT devices are delivered with the latest available firmware version. Compatibility of firmware
and hardware is mandatory; not every combination ensures compatibility. The overview below shows the
hardware versions on which a firmware can be operated.
Note
• It is recommended to use the newest possible firmware for the respective hardware.
• Beckhoff is not under any obligation to provide customers with free firmware updates for delivered
