Determining required licenses
While working in the TwinCAT development environment (XAE), TwinCAT automatically detects all required licenses. For example, as soon as a PLC project is added, a corresponding "TC1200 PLC" license is added to the list of required licenses.
In the Project Licenses tab of the TwinCAT 3 license manager you can see which licenses TwinCAT 3 has automatically determined and where the license request comes from. To open the TwinCAT 3 license manager, double-click on License in the System subtree of the Solution Explorer.
On the Manage Licenses tab, you can specify the licenses to be transferred to the License Request File. In addition to the licenses that are automatically determined as required, you can also manually add licenses to your project that you may need later.
Enabling/disabling automatic detection of the required licenses
You can use the option Disable automatic detection of required licenses for project to disable automatic detection of the licenses required for the project and select or deselect each license individually. If the checkbox is unchecked, you cannot deselect the licenses required for the project.
