NOTE
If you reset the CPU using STEP 7 and you have selected the "Format memory card" option,
you can skip step 1 of the described sequence of steps.
For detailed information on resetting the CPU to factory settings, refer to the section Reset
CPUs to factory settings (Page 338).
Result: All data that was still contained in the data memories of the modules and the SIMATIC
Memory Card has been deleted. You can now dispose of the components.
NOTE
If you no longer plan to use the SIMATIC Memory Card after formatting it, destroy it before
disposing of it.
A secure destruction method is to shred the card to such a degree that it cannot be
reconstructed. For this, you can also use a waste disposal service that specializes in data
storage medium destruction.
