Using the serial number for copy protection
You can set up copy protection for CPUs that binds execution of the block to a specific
SIMATIC Memory Card. Configuration is carried out in STEP 7 in the properties of the block
"Bind to serial number of the SIMATIC Memory Card".
You can then only execute the block if it is on the SIMATIC Memory Card with the specified
serial number (see Copy protection (Page 254)).

unauthorized reproduction in the SINAMICS S120 Drive Functions

Removing a SIMATIC Memory Card from the CPU
Note
Do not remove the SIMATIC Memory Card while a write operation is in progress.
If you remove the memory card from the CPU during a write operation, the content of the
memory card may become invalid. The memory areas can then lose their retentivity. You may
need to clear the memory card on the programming device and load the program again.
Proceed as follows to remove the SIMATIC Memory Card:
• Switch off the supply voltage.
Note
If there is no write access over the programming device in progress, you can also remove
the memory card when the supply voltage is on and the system is in STOP. In this case,
first disconnect all communication connections as a precaution.
Inserting the SIMATIC Memory Card in the CPU in STOP state triggers a re-evaluation of the
SIMATIC Memory Card. The CPU compares the content of the configuration on the SIMATIC
Memory Card with the backed-up retentive data. If the backed-up retentive data matches the
data of the configuration on the SIMATIC Memory Card, the retentive data is retained. If the
data differs, the CPU automatically performs a memory reset. A memory reset deletes the
retentive data on the CPU. After the memory reset, the CPU switches to STOP.
