An output signal to the pneumatic cylinder causes it to extend (ON state). When there is no signal, the pneumatic cylinder retracts (OFF state). The gripper is an also driven by a pneumatic cylinder. The gripper open position is an OFF state and the closed position is an ON state. In order to perform a task, the following sequence of operations must be performed: TH Sequence No. Аxis Gripper OFF OFF 1 ON OFF ON ON 3 OFF ON 4 OFF OFF The process begins when the start bush button is ON and a part triggers a limit switch. For safety, an emergency switch is used to shut off the entire system. Design a PLC ladder diagram for this application.arrow_forward
