In addition to the CPUs, further components such as SINAMICS drives dispose of integrated
safety functions. Additional information about integrated safety functions in drives can be
found in the manuals for the respective products.
Security Integrated
In conjunction with STEP 7, each CPU offers password-based know-how protection against
unauthorized reading out or modification of the program blocks.
Copy protection provides reliable protection against unauthorized reproduction of program
blocks. With copy protection, individual blocks on the SIMATIC Memory Card are linked to its
serial number so that the block can only be executed if the configured memory card is
inserted in the CPU.
In addition, all project users can be managed via the local user management. Rights such as
access rights can be set individually for each user.
Improved manipulation protection allows changed or unauthorized transfers of engineering
data to be detected by the controller.
The use of an Ethernet CP (CP 1543-1) provides you with additional access protection
through a firewall or possibilities to establish secure VPN connections.
