TwinCAT 3 system ID
The TwinCAT 3 system ID is a general, unique identification code for the respective hardware (TwinCAT 3 license dongle or IPC). Each Beckhoff TwinCAT 3 license dongle or IPC has an individual, unique system ID that cannot be changed.
The system ID of a TwinCAT 3 license dongle contains the TwinCAT platform level. Since a TwinCAT 3 license dongle does not have its own platform level due to the fact that it does not have its own CPU, the platform level is provided by the connected IPC. A TwinCAT 3 license dongle can thus have several system IDs, depending on the connected IPC. In other words, the system ID of a TwinCAT 3 license dongle always depends on the platform level of the connected IPC.
Displaying the system ID in the TwinCAT 3 development environment (XAE)
The system ID of the target system (IPC = target hardware) is displayed on the Order Information tab in the TwinCAT 3 Engineering license manager. To open the license manager, double-click on License in the SYSTEM subtree of the Solution Explorer.
The system ID of a license dongle is displayed in the dongle properties in the License Device window. To open this window, double-click on the respective dongle entry in the SYSTEM > License subtree in the Solution Explorer.
Displaying the system ID in the TwinCAT 3 Runtime (XAR)
In the TwinCAT 3 Runtime (XAR), the system ID of the IPC is displayed after a right-click on the TwinCAT 3 icon in the taskbar and a click on the About menu item in the TwinCAT System window that opens.
In the current TwinCAT version, the system ID of a connected TwinCAT 3 license dongle can not be displayed in the TwinCAT 3 Runtime.
