The demo application installed with the product, and most examples use an OPC Simulation Server that is installed together with QuickOPC. The server’s ProgID is “OPCLabs.KitServer.2”.
The demo application and the examples are designed to connect to the Simulation OPC Server in its default configuration (i.e. as shipped). In fact, some very simple examples connect to just one OPC item, named "Demo.Ramp". There are various other OPC items in this server that you can use in your own experiments too.
Note 1: When OPC proxies/stubs are not installed on the system, the installation program installs them together with the simulation server.
Note 2: On 64-bit platforms, the installation program still registers the 32-bit (x86) binary of Simulation OPC Server. This configuration gives better OPC compatibility. The 64-bit binary of Simulation OPC Server is also installed to the disk, and can be registered manually if needed.
