After startup of the system the target is moved left or right, it changes the orientation of moving when it arrives an appointed position ,and it changes the orientation when arriving another appoint position, this state continues until it receives the injunction of stop or changing the orientation,then it act accordingly. The signal of system is collected and disposed by the PLC, and the startup and stop of the electromotor which can make the moving of the target is also controlled by the PLC, the system simulates the motion of the target.
