Description
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 during
data transfer between the TIA Portal and the CPU, and to
check communication from a SIMATIC HMI system to the
CPU for possible manipulation of engineering data. The
user receives a corresponding message about manipula­
tion of engineering data detected by the integrity protec­
tion.
As an alternative to manual password input, you can con­
nect a password provider to STEP 7. A password provider
offers the following advantages:
• Convenient handling of passwords. STEP 7 reads in
the password automatically for the blocks. This saves
you time.
• Optimum block protection because the users them­
selves do not know the password.
