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.
Improved management of users, roles, and CPU func-
tion rights (User Management & Access Control,
UMAC).
You can use the local user management in the editor to
manage all project users along with their rights (e.g.
access rights) for users and roles of the project in the
TIA Portal.
You can use authorization levels to assign separate
rights to different users.
The CPUs feature an integrity protection function by
default. This helps to detect any manipulation of the
engineering data on the SIMATIC Memory Card or dur-
ing data transfer between the TIA Portal and the CPU,
and to check communication from a SIMATIC HMI sys-
tem to the CPU for possible manipulation of engineer-
ing data. The user receives a corresponding message
about manipulation of engineering data detected by
the integrity protection.
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.
