Description
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 CPU. User programs cannot run without the corre-
sponding SIMATIC memory card or CPU.
You can use authorization levels to assign separate
rights to different users.
The CPUs dispose of integrity protection by default.
Integrity protection identifies possible manipulations of
engineering data on the SIMATIC memory card or dur-
ing 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 following advantages:
• Convenient handling of passwords. STEP 7 reads the
password automatically for the blocks. This saves
you time.
• Optimum block protection because the users do not
know the password itself.
