Advantages
Safety Integrated provides the following advantages:
• Engineering with SIMATIC STEP 7 Safety Advanced in the TIA Portal
• Simple connection of PROFIsafe devices over PROFINET
• Integration in integrated system diagnostics

5.3.4 Security
Security means the protection of technical systems against sabotage, espionage and human
error.
Protection functions
For the setup of secure networks, the S7-1500R/H redundant system has an integrated
security concept:
Table 5- 5 Overview of protection functions
Protection of confidential
configuration data
Protection of confidential CPU configuration data
Integrity protection The CPUs feature an integrity protection function by default. This helps detect any manipu-
lations:
• 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
• 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
Know-how protection Protection against unauthorized access and modifications to algorithms with password
Local user management (as
of FW version V3.1)
Improved management of users, roles, and CPU function rights (User Management & Access
Control, UMAC).
You can used the local user management in the editor to manage all project users along
with their rights (e.g. access rights) for project users and roles in the TIA Portal.
