Description
Protection of confidential CPU configuration data
The CPUs come with an integrity protection function as standard. This helps detect any
manipulations:
• In the engineering data on the SIMATIC Memory Card; see also information on the integ-
rity protection of the SIMATIC Memory Card as of CPU FW version V3.1 in the next sec-
tion.
• At the engineering data during data transfer between TIA Portal and CPU
• At the engineering data during data transfer between HMI system and CPU
• At the encrypted firmware
Protection against unauthorized access and modifications to algorithms by means of pass-
word protection
Protection against duplication of programs by linking individual blocks to the serial number
of the original memory card on the SIMATIC Memory Card
