OPC Studio User's Guide and Reference
Documentation and Help
Client and Subscriber Development > Development Fundamentals > Development Product Parts > Documentation and Help

The documentation consists of following parts:

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.

See TechNet article Visual Studio 2017: Getting Started with Help Viewer for information about how to enable offline documentation in Visual Studio.

In addition, for the contextual help to work, you need to have the help preference set properly. In Visual Studio, do this:

Help -> Set Help Preference -> Launch in Help Viewer

(i.e. not Launch in Browser).
