OPC UA Server Development

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

.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 Server .NET Standard toolkit which allows development of server applications supporting OPC UA. 

The developer can concentrate on his application and servers can be developed fast and easily without the need to spend a lot of time learning how to implement the OPC Unified Architecture specification. The server API is easy to use and many OPC specific functions are handled by the framework.

The included Model Compiler can be used to create the necessary C# classes of Information Model’s specified in XML and CSV based files. At the moment the XML files must be edited by a text editor.
