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 can be tied to its
serial number so that the block can only be run if the configured memory card is inserted into
the CPU.
In addition, various access rights can be assigned in the controller to different user groups
using four different authorization levels.
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.
Design and handling
All CPUs of the SIMATIC S7-1500 product series feature a display with plain text information.
The display provides the user with information on the order numbers, firmware version, and
serial number of all connected modules. In addition, the IP address of the CPU and other
network settings can be adapted locally without a programming device. Error messages are
shown on the display directly in plain text. When performing servicing, you can minimize
plant downtimes by quickly accessing the diagnostics alarms. Detailed information about this
and a multitude of other display functions is available in the SIMATIC S7-1500 Display Simu
lator (https://support.industry.siemens.com/cs/ww/en/view/109761758).
Uniform front connectors for all modules and integrated potential jumpers for flexible
formation of potential groups simplify storage. Additional components such as circuit
breakers, relays, etc., can be installed quickly and easily, since a DIN rail is implemented in the
rail of the SIMATIC S7-1500. The CPUs of the SIMATIC S7-1500 product series can be
expanded centrally and in a modular fashion with signal modules. Space-saving expansion
enables flexible adaptation to each application.
The system cabling for digital signal modules enables fast and clear connection to sensors
and actuators from the field (fully modular connection consisting of front connector modules,
