The Config.ini [REALMAREAS] section and variables enable you to indicate the tag areas that should be permissible when no user is logged on to your application. (You may wish to protect your system by not allowing users who are not logged on to view any tag areas.)
Note: In addition to configuring the [REALMAREAS] section, you must set up security groups in order to restrict users to certain tag areas based on the group to which they've logged on. Instructions on setting up security groups are provided in Security Groups.
To specify the tag areas that should be permissible to users who are not logged onto your application, follow the syntax below.
[REALMAREAS]
Area = <area>
Area = <area>
...
In the example above, <area> indicates the tag areas permissible to users who are not logged on to the application. For example:
[REALMAREAS]
Area = Station005
Area = Station006
In this example, were a user to access the VTS application using a VIC, but was not logged on to the application, he/she would only be permitted to view those tags whose area has been configured as "Station005" and "Station006".
If you wish to configure an application so that if users are not logged on, they will not be permitted to view any tag data, set the Area variable equal to nothing, as shown below.
[REALMAREAS]
Area =
Note: The question mark (?) and asterisk (*) wildcard characters are permitted. Area declarations are not case-sensitive, nor is the [REALMAREAS] section heading.
The section that follows discusses setting permissible tag areas for viewing by super users.
Note: Detailed information on realm area filtering (including examples) is provided in Realm Area Filtering.
