Categories

Categories are groups to which each station component may be assigned for the purpose of managing who has permission to access the component.

The system provides two types of categories:

• Basic (or explicit) categories are groups (collections) to which you assign each component.

  Each component maintains a bitmap for basic category membership. The default eight categories consume one byte and each increment of eight categories you add consumes an additional byte (1–8, 9–16, 17–24, and so on) in the component record.

• Inherited categories are passed down from component parent to component child.

All components must be assigned to at least one basic category, either an explicit assignment, or an inherited assignment from a parent component. Beyond this assignment, which type of category to use depends on your needs. You may use explicit and inherited categories at the same time.
