component with the same type number, a restore process is carried out if the
Auto restore
checkbox
is enabled. Otherwise, the restore function can also be started manually with the Start restore
manually button.
7.4.4.1 Sequence of the automatic backup process
If a backup is initiated by reaching of the set time or the Backup PLC signal, the system checks whether
a user is logged on. If a user is logged on, the start of the backup is delayed until the user has logged off.
If a backup is running, the following error message is displayed on logging in at the operating system or
at the TFT display of the CS351: "Automatic backup or restore in progress. This process will be canceled
by logging on. Continue logging on?". If the message is confirmed with "YES", the running backup is
canceled. The old backup data remains changed.
If another backup is initiated while a backup process is already running (e.g. by means of a Backup PLC
signal or logging off of a user), it is not started.
If the tightening cell is switched off at the time a backup is to be started, the backup is not resumed after
the tightening cell is switched on. If the tightening cell is switched off while a backup is running, the
backup is resumed completely on restarting of the tightening system.
If a component is replaced by an incorrect component after previous backup, no backup is created of this
component if the backup is started again. The
BackupF PLC signal is set. A backup is only possible if
the backup on a component was either deleted or a new backup is created by means of the trigger
conditions of
Start auto backup . Alternatively, a backup can also be started with the Start backup
manually button. Afterwards, the BackupF PLC signal is reset.
Start backup manually
If no options are enabled under Start auto backup , the backup can be started with the Start backup
manually button.
7.4.4.2 Sequence of the automatic restore process
If the Auto restore option is enabled, the stored backup is loaded automatically after replacement of a
defective component.
In a multi-channel system, this is controlled by the communication unit. When the system is booting, the
type numbers of the (replaced) components are checked for compliance while the serial number is
deviating. Only in this case, the restore process is initiated for this component. If the type numbers of the
components are deviating, an error (error class 3) is returned.
The backup/restore process may take a few seconds up to several minutes depending on various factors:
• Is saving/backup of the firmware required or has it already been saved or is available?
• How many parameters (e.g. tightening programs, applications, jobs, etc.) are programmed/
configured?
• How often are automatic backups carried out during the tightening process?
To monitor/control the sequence of the automatic backup/restore, we recommend
using the PLC signals for auto backup/restore, see section
PLC signals from page 123 .
The tightening cell is also in operation while the backup is running and tightening processes can be
realized. The backup is running in the background. General impact on the times cannot be excluded even
with a low-priority sequence.
The tightening cell is not in operation while the restore process is running and tightening processes
cannot be realized.
