The default view of this service, the Category Browser, lets you centrally assign different objects to categories, using an expandable tree view of the station. The CategoryService also provides a Category Manager view, for you to create, edit and delete categories. Categories play an integral role in station security, where you can give users permissions for some (or all) categories. By default, the CategoryService is included when you create a new station using the New Station wizard.

In addition to being the container for child categories, the CategoryService has only one slot (property): Update Period.
| Property | Value | Description |
|---|---|---|
| Update Period | hours minutes seconds | Sets the interval at which the system automatically assigns ancestor permissions. The default value is one (1) minute. If you assign a zero value, the system disables this feature. |
| Property | Value | Description |
|---|---|---|
| Status | read-only | Indicates the condition of the network, device or component at the last check.
|
| Mode | drop-down list | There are two modes: Union and Intersection. |
| Fault Cause | read-only | Indicates the reason why a system object (network, device, component, extension, etc.) is not working properly (in fault). This property is empty unless a fault exists. |
| Index | integer | Sequential number that identifies the property in the station. |
