Based on .NET Standard you can easily develop applications supporting OPC UA as a client. Our base solution supports C#/VB.NET targeting .NET 4.6.2, .NET Standard 2.1 and .NET 5.0.
.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.
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.
