The first version contains three basic modules: Designer, OPC connectivity plugin and Data Simulation plugin. You could try to create some schema using few basic drawing tools (rectangle, ellipse and text box). On OPC side there is an ability to connect to OPC servers, scan for a list of available channels and view theirs values on “Project variables” window. The same is true for Data Simulation plugin. Have a look.
