License change for legacy products

License change for legacy products

As already announced back in April, we decided to focus in the future on OPC UA and therefore decided to provide binary versions under the MIT License.


The OPC DA/AE Server SDK .NET is licensed under the MIT License. A very liberal license that encourages both commercial and non-commercial use.
There are no separate runtime fees or royalties. The following products are available under MIT License:

Source Code

In addition we provide source code versions of those products under a commercial source code license.
There are no separate runtime fees or royalties.

Our Source Code License Agreement (PDF) allows the use of these products to develop software on and for all supported operating system and hardware platforms.

Commercial Support

For commercial support purchase a Single Standard Support request (two hours support time budget, five business days maximum initial response time, although we usually answer within one to two business days) for EUR 390,00 from Technosoftware GmbH.

After completing the purchase, please use our HelpDesk to submit your request.

By purchasing support, you agree to our Support Service Agreement.
