Backup from online device

Full backup of the CPU
With the option "Backup from online device" you create a full backup of the CPU in an
opened project with STEP 7. The following data are backed up:
● Actual values of all DBs
● Blocks of the type OB, FC, FB and DB
● PLC tags
● Technology objects
● Hardware configuration
● Actual values (bit memories, timers, counters)
● Contents of the SIMATIC memory card
● Archives, recipes
Note
Backup of current values
The "Backup from online device" type of backup backs up the current values of the tags that
are set as retentive. To ensure consistency of the retentive data, all write access to retentive
data must be disabled during the backup.
Actual values of the non-retentive data are reset to their start values during a transition for
STOP to RUN mode. When the CPU is backed up only these start values of non-retentive
data are then backed up.
Requirements
The following requirements must be met before you start the backup:
● The CPU has been set up in the project.
● The CPU is connected to the programming device/PC via the PROFINET interface.
Interfaces of CMs/CPs are not supported.
● The CPU must be in STOP mode.
● The hardware configuration and software to be downloaded have to be compatible with
STEP 7.
● You have the password for read access to the CPU or F-CPU, if an access level was
configured for the CPU or F-CPU.
