Backing up and restoring the CPU configuration

B ac kup from online device
You will make a number of changes to your plant over time, for example, add new devices,
replace existing devices or adapt the user program. If these changes result in undesirable
behavior, you can restore the plant to an earlier state. Before you load a changed
configuration to the CPU, first use the option "Backup from online device" to create a
complete backup of the current device status.
Upload f rom 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 programming device/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 device's data into a project in your PG/PC.

You can use the option "Snapshot of the monitor values" to backup the current values of the
data block, in order to be able to restore the current values if necessary at a later date.
