4.8 Backup/Restore
Following the exchange of an EL6910, EJ6910 or EK1960, the previous project can be loaded to the new
device using the
Backup/Restore mechanism.
In order to be able to use this functionality, the Backup/Restore mechanism must be enabled in the safety
project, and the terminals must be selected, on which the current CRC of the safety project is to be stored.
For a restore operation the user can specify the minimum number of selected terminals on which the correct
CRC must be stored.
Using the checkbox Restore User Administration the user can specify whether the user administration should
be transferred to the new device via the restore mechanism.
Fig. 128: Backup/Restore
In order to be able to use the Backup/Restore mechanism, create a backup of the current safety project and
store it on the hard disk of the controller, for sample. To carry out a restore, the user can either check when
starting the controller whether the serial number of the EL6910, EJ6910 or EK1960 has changed, or start the
restore manually via a service menu, e.g. in the visualization. Detailed information about the
Backup/Restore
mechanism is available from Beckhoff Support.
