Process all your schemas and fix any errors before starting a simulation.
Press the green traffic light button on the toolbar to commence a simulation run. When the simulation starts the following occurs:
- Any numeric, LED, or alphanumeric displays linked in the schemas become active on the front panel. Buttons and switches on the front panel will respond to being pressed.
- Digital and analog inputs may be manipulated on the rear panel.
- Digital and analog output values are shown on the rear panel.
- Open a schema / sub-schema to display the current values of each connection. Values in idle sub-schemas are grayed out.
Pause the simulation with the amber traffic light. Step Through the simulation using the single step icon. End it with the red traffic light.
Note that if the single step icon is pressed from a stopped simulation, the values displayed in the schema during the first step are the initialization values and not the results of the first compute loop. Subsequent presses of the single step icon will show values that are a result of the associated compute loop.
A breakpoint operator can be placed at locations of interest in the schema. Its Boolean input, when high, will pause the schema operation at the conclusion of the compute loop. This functionality allows for the creation of conditional breakpoints if desired. The hand symbol in the simulation toolbar will enable or disable all breakpoints. Note: Any breakpoint operators remaining in the schema program are ignored when it is downloaded into the actual controllers.
