Perform online backup of the configuration
To perform an online backup of the CPU configuration, proceed as follows:
1. Click the "Create online backup" button in the "PLC backup" area.
2. If the CPU is in RUN mode, the following alarm is output:
"Creation of an online backup requires PLC STOP. Do you want to set the PLC to STOP
mode?"
Acknowledge the alarm output by clicking "OK". The CPU is set to STOP mode and
online backup is performed. (If you click "Cancel", the CPU remains in the current mode
and the online backup is canceled.)
3. Save the backup file to a local directory of your PC.
4. Set the CPU back to RUN mode ("RUN" button in the "CPU operator panel" area of the
start page).
Note
During the execution of the online backup, some data is not available in the web page view
of the web server.
Scope of the backup
The backup includes all data needed to restore a particular state of a CPU, i.e. the specific
combination of the configuration of the CPU with the current values of the user-related
retentive data.
The following data of the configuration of the CPU is backed up:
● The contents of the SIMATIC memory card, e.g. configuration, program code, recipes and
archives, DataLogs
The following user-relevant retentive data is backed up:
● Retentive memory areas of data blocks, bit memories, counters and timers
● Front-panel settings, dynamic IP configuration data, operating hours counters, retentive
Motion Control sensor data
Note:
● Entries in the diagnostic buffer are not included in the backup.
● With a SIMATIC S7-1500 CPU, the current time is not saved.
● The complete content of the SIMATIC memory card is saved, i.e. also any data stored on
the card (e.g. PDF files, GSD files).
● The backup file is assigned the name of the CPU and the project with the time and date
of the backup, e.g. "2015-09-10_11-01_03_online
backup_PLC69_machineControl.s7pbkp".
● The backup file of an F-CPU also contains the collective signature of the safety program
in the file name. Check whether it is the expected F-collective signature.
● You can rename the backup, but you cannot make any changes to the contents of the
backup.
