Client Development for OPC UA

The OPC UA Client .NET Standard offers a fast and easy access to the OPC UA Client technology. Develop OPC UA 1.00, 1.01, 1.02, 1.03 and 1.04 compliant UA Clients with C#/VB.NET targeting the .NET Standard.

.Net Standard allows you develop applications that run on all common platforms available today, including Linux, iOS, Android (via Xamarin) and Windows 8.1/10 (including embedded/IoT editions) without requiring platform-specific modifications.

The OPC Unified Architecture (UA) is THE next generation OPC standard that provides a cohesive, secure and reliable cross platform framework for access to real time and historical data and events.

It’s Time to Adapt this specification for use in your applications and we recommend considering designing your application to use the OPC Unified Architecture.

We recommend considering designing your application to use the OPC Unified Architecture in the first place by using our new OPC UA Client .NET Standard toolkit which allows development of client applications supporting OPC UA. 

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.
