CAUTION!
During the backup process, the USB stick should not be removed and the
power should not be turned off. This can destroy the firmware of the compo-
nents and makes further operation impossible.
To store a backup a service USB stick is needed. The USB stick can be pre-
pared via KeStudio U4 (For further information see onlinehelp of KeStudio
U4).
During backup, the data stored on the CFast card will be saved. The sets of
parameters of the drives are usually on the drive and have to be stored first
on the CFast card. This can only be done at operating mode STOP or RUN.
To store the sets of parameters of the drives proceed as follows:

via Menu-Drv[n] - Drive[n] Menu D[n]-4 Service - D[n]-4 Service

The set of parameters of the desired drive are stored on the CFast card un-
der /appldisk/application/drive. Repeat this for further drives if neces-
sary.
