Description
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 come with an integrity protection function as
standard. This helps to detect possible manipulations of
the engineering data on the SIMATIC Memory Card or
during data transfer between the TIA Portal and the CPU
and to check communication from a SIMATIC HMI system
to the CPU for possible manipulations of engineering
data. The user receives a corresponding message about
manipulations of engineering data detected by the integ­
rity protection.
As an alternative to manual password entry, you can link
a password provider to STEP 7. A password provider
offers the following advantages:
•
Convenient handling of passwords. STEP 7 automatic­
ally imports the password for the blocks. This saves
you time.
•
Optimum block protection because the users do not
know the password itself.
