QuickOPC ships with certain internal testing tools that might be of interest to advanced users, and were created partially in relation to OPC compliance certification process.
The test tools are not installed by default; you need to select “Custom Install”, and then specifically enable them on the “Select Components” page in the installation wizards. After installation, the test tools can be reached through the Start menu or the Launcher application, in the “Test Tools” group.
There is a separate document (online) that contains the list of test tools, their purpose, and instructions on how to operate the tools. When the Test Tools are installed, you can access it from the Start menu as well.
