Beckhoff is not under any obligation to provide customers with free firmware updates for delivered products.

Notice

Risk of damage to the device!

Pay attention to the instructions for firmware updates on the separate page.
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!
