Troubleshooting

Problems with TwinCAT 3 licensing can usually be pinpointed and resolved with a few standard checks. In the following section they are divided and described in three categories.

Troubleshooting 1:

TwinCAT 3 licenses for non-Beckhoff IPCs

If you use an IPC from a manufacturer other than Beckhoff (TwinCAT 3 platform level >= 90), a TwinCAT 3 license dongle is always required for licensing TwinCAT 3.

Troubleshooting 2:

Several system IDs

A TwinCAT 3 license dongle has no platform level of its own. This is dependent on the platform level of the connected computer. Since the platform level of the computer goes into the system ID of the dongle, a TwinCAT 3 license dongle can have several system IDs.
