Clarification on how the KT03 firmware upgrade by Bus can fail;
- The upgrade can be stopped by pressing cancel
- there may be an error message to stop the upgrade
These will require the upgrade to be started again
However it is quite unlikelly that the firmware upgrade will fail
If there is a loss of ethernet connection for UCM/ETH02 Comfigurator 3.6.5 will ask \"Do you want to continue from the last address\". If you select OK, the upgrade will continue so this situation is not a problem. This is the more likely scenario
