是否有 OPC UA .NET 官方 API 参考和文档？

Question

I can't find any official docs online to describe the .NET API for OPC UA, aside from some code samples and a big specifications document.

Just want to check if there are API reference docs and guide some where for .NET platform, before I continue to study the sample code and figure out what the methods and classes do?

We need to convert some small code service from OPC classic to OPC UA, so I don't have much time to reverse-engineer code or read too much.

Answer 1

There are few available:

Unified Automation .NET OPC UA SDK API Reference.

https://documentation.unified-automation.com/uasdkdotnet/2.0.0/index.html

Github

http://opcfoundation.github.io/UA-.NETStandard/

https://github.com/OPCFoundation/UA-.NETStandard

https://github.com/OPCFoundation/UA-.NET-Legacy (Deprecated now)

Unified Architecture: https://opcfoundation.org/developer-tools/specifications-unified-architecture/

Answer 2

Except from Source code documentation, there are also Getting Started guides.

Based on what your sample example are doing it could be also necessary to read the OPC UA Specification .

Sorry: my mistake the Getting Started link was already provided... you can use docfx to generate the API Reference Documentation from source code. There is not more available.

[2nd Edit] Did you consider just using a generic Classic OPC to OPC UA wrapper instead of rewrite? It can save you alot of time. See UA-.Net Standard Library COM Server Wrapper
