When transferring data to the second bus operator unit, local data backup of the
second unit will be overwritten, which means that locally saved settings of the sec-
ond unit will be lost. The date of local backup will be overwritten by the date on which
the data are transferred

To avoid loss of data, the bus operator units involved must not be switched off or
removed during data transfer
•
The bus operator unit cannot be used during the time data are transferred. To avoid
data corruption, simultaneous data backup or data restoration must not be performed
on the second unit
