On the SD card, in addition to the customer-specific configuration that was compared against that in the flash memory of the PLC upon starting the crane, a separate backup of the customer-specific configuration can be created.

With this function, the current customer-specific crane configuration is saved and stored as a separate backup on the SD card. This backup remains on the SD card until a new backup is carried out. The new backup overwrites the previous backup.

This means that a certain configuration status (e.g. directly after the test before the first commissioning) is saved. This can be restored later (e.g. after unsupervised changes).

For this work step, access from a laptop or tablet computer to KranOS is necessary. The user "Abnahme" (commissioning) (user level ‚[2]) must be logged in.

Log in as user "Abnahme" (commissioning) (user level [2]) in KranOS. See Connecting laptop or tablet computer with ABUControl, page  .
