Description
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.
The CPUs support PID basic functions.
No controller support:
PID_Compact
•
PID _3Step
•
PID_Temp
•
The know-how protection protects user blocks against
unauthorized access and modifications.
You can use authorization levels to assign separate
rights to different user groups.
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.
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.
