4. Explanation
In this example, the working motor is connected to the conveyor belt. The moving conveyor is
required to reach a certain position.
Forward button and reverse button enable the motor to rotate in both forward and reverse directions
momentarily. This mode can be achieved by: giving a button input, the selected pulse output is generated,
thereby driving the motor.
Use the pulse function to ensure that each press of a button, only output a program scan cycle, which
also means that the length of the button input time and the motor is not driven.
This case uses the PLS form of the pulse command to ensure that there is a button input that
immediately drives the output.
