Firmware compatibility
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
products.
Risk of damage to the device!
Pay attention to the instructions for firmware updates on the separate page [} 172]. If a device is placed in
BOOTSTRAP mode for a firmware update, it does not check when downloading whether the new firmware
is suitable. This can result in damage to the device! Therefore, always make sure that the firmware is
suitable for the hardware version!
