Hi Innovative1, and welcome to the forums! I'm thinking what you need is in the PAC Sim Readme. Unfortunately we seem to have buried the basic instructions in the last half of the Readme. (We'll have to fix that.) Anyway, take a look at pages 4-6 and see if they give you a start.
Have you already downloaded PAC Control? It's free and you'll need it to configure the controller and start building your control program.
If this doesn't help, let us know.
