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.
