Extended profiles provide additional access control for vector and station forms.
As an example of increased access control through extended profiles, you can use an extended profile to grant access to a specific set of vectors. For example, a user profile has read-only (r-) access to the vector form in the standard profile. The extended profile grants access to vector 3 only. The user is able to display vector 3 and is able to list vectors. A user with these restrictions can see (list) all vectors, but can read the detail parameters only for vector 3.
