# Functionality Management System Definitions

Distribution of functionality to controllers
License distribution | Function
--- | ---
Local License Server (LLS) | A unit that holds the pool of feature items and that can distribute the feature items to the license manager in a controller.
Atlas Copco license portal (ACLP) | A unit that can send a license file, containing all the desired feature items, to the customer.
License | Access rights to feature items. The license states the conditions for how the feature items may be used.
License Manager | A function in the controller that loads, manages and returns feature items.
Virtual Station Type | A license for a fixed collection of features bundled together that are assigned in its entirety to a virtual station. For handheld systems.
Sync Functionality | A license for a fixed collection of features bundled together that are assigned in its entirety to a virtual station. For a fixtured system.
Virtual Station Feature | A license for an individual controller feature, for example TurboTight or TrueAngle.
Controller Feature | A license for a controller-wide feature, for example Step Sync or Soft PLC. These are assigned per controller and are not restricted to any virtual station on that controller.
Feature item | A piece of software code that can be loaded into the controller to provide additional functionality. The usage conditions are covered by the license agreement.
Intelligent Application module (IAM) | A storage module that contain all the controller programs, configurations and results. Certain modules may also include additional loaded feature items.
Reservation list | The distribution server has a pool of feature items. Some of them are allocated to controllers and some are free for distribution. The reservation list contains information on how feature items are allocated.
Borrow time | Applicable in a networked distribution environment. A controller must periodically check with the LLS and synchronize its feature items with the reservation list.
Expired license | Changes may be made in the controller configuration or program, and a mismatch between the loaded feature items and the content of the reservation list may occur. In this case an error event will be displayed if a feature item is used that has expired on the controller.
Capability file | The binary file that is downloaded from the ACLP. It contains all the valid feature items. When it is decoded and stored on the server, a pool of feature items is available for distribution to the controllers.
