# Working with the License Assignment Tab

Many features and functions in the tool require a license in order to be assigned and used by the virtual station. There are three types of licenses:

- Virtual Station Type

  A fixed collection of features bundled together in a single package. The Virtual Station Type license determines, among other things, what tools can be run, how many programs and sequences can be used, which tightening strategies are available, and the type of reporting that can be done. The features contained in each Virtual Station Type are features that often are used in conjunction with each other, or which have internal dependencies that require the presence of other features in the package. Virtual Station Types are assigned in their entirety to a virtual station. The virtual station can then make use of all features contained in the Virtual Station Type. In order to be able to perform tightenings, a Virtual Station has to be assigned a Virtual Station Type license. Depending on the license type, various tightening options will be enabled or blocked.

- Virtual Station Feature

  Individual features can be purchased as a single licenses to complement the virtual station type licenses.

## License Sources

Licenses used on a tool can be pulled from several different sources. The number of simultaneous sources is limited to 10 FMS Portable sources. If you would like to add licenses from a source when the source limit (10) has been reached, all licenses from one source need to be removed from the tool to make room for licenses from the other source.

The Source Overview tab (License assignment > Source Overview) provides the user with an overview of the licenses installed on the tool, as well as where they were installed from. A maximum number of 10 different sources can be displayed here, and each will be designated with FMS P (for FMS Portable, or dongle).

Clicking on any license source will present that source's detailed license source information. It lists the source name and type, as well as the number and type of licenses in each category (Virtual Station Type, Virtual Station Feature).

Configuration of features governed by licenses can be done even in the absence of an installed license, for example, configuration of tightening programs. Assigning these features to a tool or virtual station is also possible. However, running the feature without a valid license will require the installation of the appropriate license.

License enforcement is performed at two stages: assignment and runtime. If a feature for which no license is installed is assigned to a virtual station, a red exclamation mark will appear in the tool or task section (depending on what is missing) in the GUI. If a feature for which no license is installed is started, an event will be presented to the user informing the user of which license is missing. It will not be possible to proceed without a correct license installed. Running an unlicensed feature will, in most cases, result in a locked tool.
