Mode-firmsafe

Of the two firmware versions saved in the device only one can ever be active. When loading a new firmware version the active firmware version is not overwritten. You can decide which firmware will be activated after the upload:

O 'Immediate': The first option loads the new firmware and activates it immediately. This can result in the following situations:
o The new firmware is loaded successfully and works as desired. Then all is well.
o However, if the new firmware does not operate correctly, it may not be possible to communicate with the device after the restart. If an error occurs during the upload, the previous firmware version will remain active and the device will continue to operate normally.
O 'Login': To prevent problems caused by defective firmware, the second option will load the firmware and start it immediately.
o In contrast to the first option, the firmsafe will wait until it has successfully logged on. The new firmware will only be permanently activated when the login occurs successfully within the time set under 'Timeout firmsafe'.
o If the device no longer responds and it is therefore impossible to log in, the firmware automatically loads the previous firmware version and reboots the device with it.
O 'Manual': The third option allows you to set a period (Timeout firmsafe) beforehand for testing the new firmware. The device will start with the new firmware and wait for the preset period until the loaded firmware is manually activated and therefore becomes permanently effective.
