Security settings enable you to secure the run-time environment and restrict or prohibit specific operator actions. For example, you can prohibit the operator from closing the current picture and switching to another application.
The User Preferences dialog provides the means to define the DeltaV Operate start environment. To ensure security in your plant, it is very important that you carefully develop your security scheme before making changes to the start environment. Refer to the online help and Books Online for more information before making changes to the User Preferences dialog.
