The DeltaV FlexLock application creates dual desktops on a single workstation to provide both a secure operating environment and a wide open engineering environment. Access to a desktop is determined by the current user's privileges.
You can access online help for FlexLock by pressing F1.
Clicking the FlexLock icon in the left corner of the FlexLock window opens the System menu. The menu contains Windows standard options and FlexLock options.
The available desktops are the Windows desktop and the DeltaV desktop. A user who is a member of the DeltaV Admins, Administrators, or DeltaV Access Windows group has access to both the DeltaV desktop and the Windows desktop. The Windows desktop includes all of the DeltaV programs as well as all programs available in Windows. A user who is not a member of one of these groups has access only to the DeltaV desktop. The DeltaV desktop limits the user to the operator application and those applications available to the user through the operator application.
To secure your operating environment, consider giving operators access to the DeltaV desktop and other users, such as engineers, access to both the DeltaV desktop and the Windows desktop.
You must also consider access to the underlying Windows account, especially when logged on with Windows administrator privileges. When you log off of the DeltaV software, be sure to log off of Windows also, especially if you are logged on with Windows administrator privileges. If you do not log off of Windows, the next user to log on to the DeltaV system will operate under the Windows account that has administrator privileges. Windows administrator privileges grant the user the right to perform actions that could interfere with the operation of the DeltaV system. In the Windows User Manager, consider creating an administrator group for users with unrestricted rights and an operator group for users with restricted rights.
