Hi Experts. 

I'm using wincc 7.2. User administration has been configured with usernames and passwords.  How do I restrict some users from changing values to some specific objects. Restrictions to change limit values for specific level transmitter.  

Thanks 

Hello TeeGee,

you can not give restrictions.
In the WinCC Useradministrator you can give special authorizations
to the users.

see manual:
"WinCC V7.2: Working with WinCC"
"Adding authorizations"

And in the Graphics Designer you can configure these authorizations
for the objects, like a button.

see manual:
"WinCC V7.2: Working with WinCC"
"Configuring operator authorization"
