Formatting a SIMATIC Memory Card
Note
Formatting the SIMATIC Memory Card
Do not format the memory card with Windows tools. Formatting with Windows renders the
memory card initially unusable by a CPU.
You can find information on how to repair an inconsistent or incorrectly formatted card in the
following FAQ on the Internet
(https://support.industry.siemens.com/cs/ww/en/view/69063974).
To free up memory space on your SIMATIC Memory Card, you have the option of formatting
the SIMATIC Memory Card. During formatting, the entire contents of the memory card
including the project data of the SINAMICS Integrated are deleted.
The SIMATIC Memory Card may only be formatted in the CPU. Proceed as follows with the
SIMATIC Memory Card inserted:
Formatting with STEP 7:
• Establish an online connection.
• Open the online and diagnostics view of the CPU (either from the project context or via
"Accessible devices").
• In the dialog window, select "Functions > Format memory card" and then select the
"Format" button.
Results:
• The SIMATIC Memory Card is formatted.
• The CPU is temporarily unavailable.
• The project data on the CPU is deleted with the exception of the IP address.
Replacing the SIMATIC Memory Card without loss of retentive data
You can change the SIMATIC Memory Card or use a larger SIMATIC Memory Card without
losing the retentive data. When you switch off the CPU, the retentive data is backed up in the
retentive memory of the CPU. While the CPU is off, you can remove the memory card and
copy its content to a larger memory card. After the CPU is switched on, the data backed up in
the CPU when the CPU was switched off is restored.
