License overview in the TwinCAT 3 Runtime (XAR)

If you do not have access to the TwinCAT 3 development environment and the current project, you can determine the license status of your control computer via the TwinCAT 3 Runtime.

You have access to the Windows Desktop (via remote desktop or a connected monitor and mouse) on the control computer.

1. Right-click on the TwinCAT Runtime icon in the Windows taskbar.

With a TwinCAT 3 license dongle the license status is "Pending" if there is no connection to the associated TwinCAT 3 license dongle.

The Device Type ID is displayed from TwinCAT Version 3.1 Build 4022.4. This is an item of internal information that identifies the device type.

	Only validated TwinCAT 3 licenses switch the EtherCAT bus to status "OP". If the EtherCAT bus in TwinCAT 3 Run mode is not in "OP" state, the required TwinCAT 3 licenses could probably not be validated. This may be the case if a TwinCAT 3 license dongle is used, for example, and the License Response File does not match the TwinCAT 3 license dongle used.
