Benefits
SIMATIC Safety Integrated provides you with the following advantages:
• Engineering with SIMATIC STEP 7 Safety Advanced in the TIA Portal, same engineering and
operating concept for standard and fail-safe automation task
• Use of instructions approved by the German Technical Inspectorate from the system
library Safety in the safety program, e.g. for protective door, emergency stop, monitored
feedback loop circuit and user acknowledgment, saves time and reduces the error rate
• Simple connections of PROFIsafe devices via PROFINET and PROFIBUS

Description
Protection of confidential
configuration data
Protection of confidential CPU configuration data
Integrity protection The CPUs come with an integrity protection function as standard. This helps to detect possi-
ble manipulations:
• 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 encrypted firmware
Know-how protection Protection against unauthorized access and modifications to algorithms by means of pass-
word protection
Copy protection
Protection against duplication of programs by linking individual blocks with the serial num-
ber of the original memory card on the SIMATIC memory card
Access protection
Protection against unauthorized configuration changes using authorization levels
Locking the CPU
Protection against unauthorized access by locking the front cover with a seal or a lock
