1.8 Simulating Logic¶
To simulate the current configuration, click the Simulate button in the toolbar, or press F5 on the keyboard. This compiles the configuration to be run as a simulation, and then shows the simulation controls window.
In the controls window, the speed of the simulation can be changed, and the logic can be stepped 1 ms, 10 ms, 0.1 s, or 1 s at a time.
Pressing Reset resets the simulation to its original state.
Figure 1.36: The simulation controls window.
While simulating, the pins of input functions can be manipulated by clicking with the mouse on different parts of the block:
- Press the icon of the block to toggle the entire function between OFF and ON-state.
- Press the OFF text to set all pins to OFF-state.
- Press the ON text to set all pins to ON-state.
- Press on a pin to toggle that pin between OFF and ON (can be used to test input two-channel errors).
Figure 1.37: The different areas in an E-stop block where the user can click during simulation.
When simulating blocks that are missing connections, the simulator will create simulation input/output blocks and connect them to the empty connectors. These blocks can be used to manipulate the input signals of a block. See Figure 1.39 and Figure 1.38.

1.8.1 Simulating errors¶
During simulation, errors on inputs and outputs can be simulated.
Figure 1.40: Turning off and on pin 4 during simulation shows a two-channel error.
