The CODESYS OPC UA Server SL is not compatible with application-based licenses.
CODESYS OPC UA Server SL
An additional option for CODESYS runtime systems to publish variables via the OPC UA protocol. For advanced use cases the linkage of an information model to the PLC application is possible.
The OPC UA Server exposes specified variables of a CODESYS project to the OPC UA address space. Clients can read, write and monitor the values of the PLC. Custom information models can be easily imported and linked to the PLC application. This also enables the execution of PLC methods by clients.

Licensing
Single Device License: The license can be used on the target device/PLC on which the CODESYS Runtime System is installed.
Licenses are activated on a software-based license container (soft container), which is permanently connected to the controller. Alternatively the license can be stored on a CODESYS Key (USB-Dongle). By replugging the CODESYS Key, the license can be used on any other controller.
Note: In demo mode, the software runs for two hours without a license. After that, a manual restart is required.
Required Accessories
Optional: CODESYS Key
