The DeltaV system offers dual desktops, the Windows desktop and the DeltaV desktop, to provide both a secure operating environment and open engineering environment. The Windows desktop allows access to DeltaV applications and Windows resources, including other Windows programs that might be on the system. The DeltaV desktop limits the user to the DeltaV Operate or DeltaV Live application and to those applications available to the user through DeltaV Operate or DeltaV Live.
Access to the Windows desktop is determined by the current user's privileges, which are based on group membership. A user with Windows administrative, DeltaV administrative, or DeltaV access privileges has access to both the DeltaV desktop and the Windows desktop. A user who is not a member of the Administrators group, the DeltaV Admins Group, or the DeltaV Access group cannot access the Windows desktop.
Initial DeltaV configuration defaults to the DeltaV desktop. Users with the proper privileges can switch to the Windows desktop. Unprivileged users are limited to the DeltaV desktop. This default setting can be changed so that all users (regardless of their privileges) go directly to the Windows desktop upon logging on to the system.
To secure your operating environment, consider giving operators access only to the DeltaV desktop and other users, such as engineers, access to both the DeltaV desktop and the Windows desktop.
Keep the default setting to restrict unauthorized users from accessing the Windows desktop.
