3.12 Online backup
Restoring the configuration
To restore the CPU configuration, follow these steps:
1. Enter the password of the currently logged-in user in the "Restore PLC" area.
2. Click the "Select file" button and select the backup file of the configuration that you want
to restore.
3. Click "Restore selected online backup".
4. If the CPU is in RUN mode, the following alarm is output:
"Download online backup to device. The CPU is set to STOP and the contents of the
CPU will be overwritten. Do you want to continue?"
If the CPU is already in STOP mode, the following alarm is output:
"Download online backup to device. The contents of the CPU will be overwritten. Do you
want to continue?"
Acknowledge the alarm output by clicking "OK". The CPU is set to "STOP" mode if
required, and the online backup is downloaded. (If you click "Cancel", the CPU remains in
the current mode and downloading is canceled.)
5. An alarm informs you that you must not leave the web page during the "restore
procedure". Acknowledge the alarm output by clicking "OK".
The restoration of the CPU configuration starts and you will be continuously informed of
the current status:
– "Download of online backup has been started."
– "Checking backup file."
– "Formatting memory card and resetting CPU."
6. If you have started the restoration procedure with a user name and password defined in
the Web server configuration, you will be asked to enter these again after restoration of
the CPU. Enter the required information and click "Login".
If you have started the restoration procedure as the user "Everybody" without a password
(but with appropriate access rights), this prompt is not displayed.
Note
To restore the configuration of an F-CPU whose security program and/or password has
been changed for the F-CPU in the meantime, you also need the access authorization
"Perform changes as F-Admin"; see "Amending user management" in the section
Configuring the Web server (Page 19).

WARNING
The authorization "Perform changes as F-Admin" on the web server without password
protection (user "Everyone") is only for test purposes, commissioning, etc. i.e. only when
the system is in productive operation. In this case, you have to ensure the security of the
plant through other organizational measures, e.g. through spatial protection.
Before the transition to productive operation, you must remove the right "Perform
changes as F-Admin" from the user "Everybody".
The password of the user of the web server with the right "Perform changes as F-
Admin" must only be accessible to authorized persons.
