Examples in the Product and on the Web

This documentation section consists of several parts:

Depending on whether you develop OPC applications for Microsoft .NET, or are using Microsoft COM, please refer to the corresponding part.

Examples are provided for OPC “Classic” (COM-based) specifications, OPC XML-DA, and OPC Unified Architecture (OPC UA).

The OPC Data Client installation contains usage examples in various programming languages. The examples are being updated and enhanced more frequently than the base product, so if you like them, please check for newer builds of OPC Data Client from time to time.

Note that the examples are different for OPC Data Client.NET and OPC Data Client-COM. The text is marked with corresponding .NET or COM icon further below.

For those who want to use the command-line interface, a "Command Prompt From Here" links are installed into example folders that are related to command prompt, such as JScript Examples in WSH, PHP Console Examples, and VBScript Examples in WSH (Windows Script Host). These links allow you to switch from the Windows Explorer to a CMD window with the current directory set to the chosen place, for quick experiments and exploration.
