The know-how protection protects user blocks against unauthorized
access and modifications.
Copy protection links user blocks to the serial number of the
SIMATIC memory card or to the serial number of the SIMATIC
Drive Controller. User programs cannot run without the correspond-
ing SIMATIC memory card or SIMATIC Drive Controller.
Extended access protection provides high-quality protection against
unauthorized configuration changes. You can use authorization
levels to assign separate rights to different user groups.
The CPUs dispose of integrity protection by default. Integrity protec-
tion identifies possible manipulations of engineering data on the
SIMATIC memory card or during data transfer between TIA Portal
and CPU.
Integrity protection also checks the communication from a SIMATIC
HMI system to the CPU for possible manipulations of engineering
data.
If integrity protection identifies the manipulation of engineering data,
the user receives a corresponding message.
As an alternative to manual password input you can connect a
password provider to STEP 7. A password provider offers the fol-
lowing advantages:
Convenient handling of passwords.
•
STEP 7 reads the password automatically for the blocks. This
saves you time.
Optimum block protection because the users themselves do not
•
know the password.
