Users must "Login" using a Username and password. All Web Browser Clients must Login to see any graphic displays or data. User names are not case sensitive. Passwords are case-sensitive.
All users are assigned a User Type. The user type determines which displays and types of displays a user can View. User type is used to restrict the ability to view data. The User Types are administrator, power user, user manager, general user and restricted user.
If the login is through a Web Browser, a restricted user can view only displays assigned to that user (this may be a single display).
Security Area and security Level are used to restrict the ability to change data. In order to change the value of a tag, both the user and the tag must be assigned to the same Area and the user must have a security Level greater or equal to the security level assigned to the tag.
