SIMATIC memory card
11.1 SIMATIC memory card - overview
Formatting a SIMATIC memory card
Note
Formatting of a SIMATIC memory card may only be carried out in a CPU; otherwise the
SIMATIC memory card cannot be used in the CPU.
If you want to format the SIMATIC memory card using STEP 7, an online connection to the
relevant CPU must exist. The CPU is in STOP mode.
Proceed as follows to format a SIMATIC memory card:
1. Open the Online and Diagnostics view of the CPU (either from the project context or via
"Accessible devices").
2. In the "Functions" folder, select the "Format memory card" group.
3. Click the "Format" button.
4. Click "Yes" in response to the confirmation prompt.
Result:
● The SIMATIC memory card is formatted for use in the CPU.
● The data on the CPU is deleted with the exception of the IP address.
Service life of a SIMATIC memory card
The service life of a SIMATIC memory card depends essentially on the following factors:
● Number of delete/write cycles
● External influences, such as ambient temperature
At an ambient temperature of up to 60 °C, at least 50,000 delete/write processes are
possible on the SIMATIC memory card (see Technical specifications of the individual SMCs).
