12.7 Backing up and restoring the CPU configuration
Backup from online device
You may make changes in the operation of your plant. For example, you may add new
devices, replace existing ones or adapt the user program. If these changes result in
undesirable behavior, you can restore the plant to an earlier state. Before you download a
changed configuration to the CPU, first use the option "Backup from online device" to create a
complete backup of the current device state. If you have assigned a password to protect
confidential PLC configuration data, then this password is not saved. You can find more
information on passwords in the section Protection of confidential configuration data
(Page 224).
Upload from device (software)
With the option "Upload from device (software)", you load the software project data from the
CPU to an existing CPU in the project.
Upload device as new station
If you are operating a new PG/PC in the plant, the STEP 7 project that was used to create the
plant configuration might not be available. In this case, you can use the option "Upload
device as new station" to load the data to a project in your PG/PC.
Snapshot of the monitor values
To allow you to restore the actual values at a later date, back up the actual values of the data
blocks using the option "Snapshot of the observed values".
