OPC UA Client Development

The OPC UA Client .NET offers a fast and easy access to the OPC Unified Architecture (UA) technology. 

Develop OPC UA compliant Clients with C# targeting .NET 10.0, .NET 9.0 and .NET 8.0. For backward compatibility we also provide .NET 4.8 and .NET 4.7.2 support.

.NET 10.0, .NET 9.0 and .NET 8.0 allows you develop applications that run on all common platforms available today, including Linux, macOS and Windows 11/10 (including embedded/IoT editions) without requiring platform-specific modifications.

The OPC UA Client .NET API defines classes which can be used to implement an OPC client capable to access OPC servers supporting different profiles with the same API. These classes manage client side state information; provide higher level abstractions for OPC tasks such as managing sessions and subscriptions or saving and restoring connection information for later use.

The OPC UA Client .NET is based on the OPC Foundation stack with several enhancements to make the development smooth and efficient. While we use the OPC UA Client .NET mainly in our own services it is also possible to use it in your own development.
