Now that the user has made their program they can simulate it to see how it will work in the real world. Go to the top and click on the S button. This will start the Simulation mode. Once in simulation mode they can turn their inputs ON and OFF by clicking on them and they can see everything that happens inside the controller as well as the state of the outputs. The user can even see what is displaying on the controller’s screen. To stop the simulation just click on the E button. This will get the user back into the Edit mode.
