The documentation consists of following parts:

• User's Guide and Reference (online). The reference is formatted according to Visual Studio style and standards, and integrates with Visual Studio help system. This document include, among other content: 
  • Getting Started. Short step-by-step instructions to create your first project.
  • Examples in .NET Framework, .NET 6+, Python and COM.
  • Documentation for product options (such as Excel Connector).
  • Reference.
• What’s New (online). Contains information about changes made in this and earlier versions.    

Because the COM components are implemented by exposing the .NET objects of OPC Data Client to COM, you may need to refer to OPC Data Client reference documentation in order to find information about COM objects and interfaces of OPC Data Client as well.

 

You can access all the above mentioned documentation from the Start menu or the Launcher application.

In addition, there is IntelliSense and Object Browser information available from the Visual Studio environment.

The OPC Data Client help contents integrate Microsoft Visual Studio 2019 or 2022 Help (Microsoft Help Viewer 2 format). This also means that the reference documentation works as a contextual help; e.g. pressing F1 when the cursor is on some of the OPC Data Client types or members invokes directly the help page for that type or member.
