The know-how protection protects user blocks against unauthorized access and
modifications.
Copy protection links user blocks to the serial number of the SIMATIC memory card or
to the serial number of the CPU. User programs cannot run without the corresponding
SIMATIC memory card or CPU.
Extended access protection provides high-quality protection against unauthorized
configuration changes. You can use authorization levels to assign separate rights to
different user groups.
The system protects the data transferred to the CPU against manipulation. The CPU
detects erroneous or manipulated engineering data.
