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 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 possi-
ble 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 entry, you can
link a password provider to STEP 7. A password
provider offers the following advantages:
Convenient handling of passwords. STEP 7 au-
•
tomatically imports the password for the blocks.
This saves you time.
Optimum block protection because the users do
•
not know the password itself.
