Formatting the SIMATIC memory card
Note
You may only format a SIMATIC memory card in the CPU as otherwise the SIMATIC
memory card will be rendered useless for use 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:

"Accessible devices").
2.
In the "Functions" folder, select the "Format memory card" group.
