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 5.0, .NET Core 3.1 or .NET Standard 2.1. For backward compatibility we also provide .NET 4.8, .NET 4.7.2 and .NET 4.6.2 support.
.NET 5 and .NET Standard allows you develop applications that run on all common platforms available today, including Linux, macOS 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.
