Protection of confidential CPU configuration data
Integrity protection The CPUs feature an integrity protection function by default. This helps detect any manipula
tions:
• To the engineering data on the SIMATIC memory card
• To the engineering data during data transfer between TIA Portal and CPU
• To the engineering data during data transfer between HMI system and CPU
• To the synchronization data during data transfer between primary and backup CPU
• To the encrypted firmware
Access protection Protection against unauthorized configuration changes via four or five (for HF-CPU) authoriz
ation levels
Know-how protection Protection against unauthorized access and modifications to algorithms with password pro
tection
CPU lock Protection against unauthorized access by locking the front cover with a seal or a lock
