Function
Description
Additional information
RT (real time)
RT prioritizes PROFINET IO frames over standard
frames. This ensures the required determinism in the
automation technology. In this process the data is
transferred via prioritized Ethernet frames.

MRP (Media Redundancy
Protocol)
The Media Redundancy Protocol enables the configu-
ration of redundant networks. Redundant transmission
links (ring topology) ensure that an alternative commu-
nication path is made available if a transmission link
fails.
Within the PROFINET ring, the H-CPUs assume the
role of the MRP Manager following appropriate project
configuration and all other devices in the ring assume
the role of the MRP clients.
PROFIenergy
PROFIenergy is a PROFINET-based data interface for
switching off consumers centrally and with full coordi-
nation during pause times regardless of the manufac-
turer or device type. Through this, the process should
only be provided with the energy that is absolutely
required. Most of the energy is saved by the process.
The PROFINET device itself only contributes a few
watts to the savings potential.

Security Integrated
Know-how protection
The know-how protection protects user blocks against
unauthorized access and modifications.

Access protection
You can use authorization levels to assign separate
rights to different user groups.
Integrity protection
The CPUs dispose of integrity protection by default.
Integrity protection identifies possible manipulations of
engineering data on the SIMATIC memory card or
during data transfer between STEP 7 and the CPUs.
Integrity protection also checks the communication
from a SIMATIC HMI system to the CPUs for possible
manipulations of engineering data.
If integrity protection identifies the manipulation of en-
gineering data, the user receives a corresponding mes-
sage.
Password provider
As an alternative to manual password entry, you can
link a password provider to STEP 7. A password pro-
vider offers the following advantages:
•
Convenient handling of passwords. STEP 7 auto-
matically imports the password for the blocks. This
saves you time.
•
Optimum block protection because the users do not
know the password itself.
