Titas Posts: 94 Rating: (15)	Hello Phantom75, I have a server with 2nos client. Now when I change any parameter of the object ( like change of PID value)thenfrom the other clientany other operator should not change the parameter of the same object. For this requirement acess protection required for the objects. But how to do that I could not understand. Please guide. Regards :- Titas

Dear Titas, Now I understand what exactly you need... I am afraid, at the CFC level nothing is possible (that I could think of)... One solution is to create 2 user levels in WinCC User Administration called CLIENT A and CLIENT B. Now, for each object that "A" can access, you should enable level A and for each object that "B" can access enable level B. So, depending on the client login, the access protection will be determined. Regards PS: For standard WinCC objects, you can see access protection in Object Properties.

Titas Posts: 94 Rating: (15)	Hello Phantom75, I can not make any User administrative right in the serverfor the clients. I have to make individual user administrator settings for individual client then how I know the status of other client from one client. Regards :- Titas

The User Administration settingsare client dependent (server has nothing to do with it). So, in your case both clients will have user level Client A & Client B in user administration (identical). In the server you'll set the access protection level for each object (in the PDL). So, if I login as "Client A", I'll be able to control only those objects for whichuser level"Client A" has been enabled. Regards

Titas Posts: 94 Rating: (15)	Dear Phantom75, I understand your suggestion and It is working also. But this is indirect way and segiration of objectsis required in the server. But in the same object if I want to make access protection forboth theclients then I think not possible in the PCS 7. Thanks and regards : Titas

Hi Titas, This way is the only way when you have objects on the same screen some of which only Client_A can access and some of which only Client_B can access. A much better approach would be to segregate your objects onto 2 screens, Screen_A and Screen_B and have a common custom level (created in User Admin) enabled in all objects. Then, for Client_A you enable Screen_A and for Client_B you'll enable Screen_B in the User Admin. Regards
