Seeking automatic door PLC system control program Ladder diagram of the overall wiring diagram of the hardware PLC sequence diagram immediately use ah Thank you
With the ladder, the other are good pick up, if the ladder can not draw the words, then you can bid farewell to the ladder,
1. Automatic door control device hardware components: automatic door control device by the door photoelectric detection switch K1, the door outside the photoelectric detection switch K2, open the door limit switch K3, close to the limit switch K4, open the door actuator KM1 (so that the DC motor Switch), closing the implementation of the KM2 (to reverse the DC motor) and other components. 2. Control requirements: 1) When someone from inside to outside or from outside to inside through the photoelectric detection switch K1 or K2, the door open actuator KM1 action, the motor forward, reach the door limit switch K3 position, the motor stops running. 2) the automatic door in the open position to stay for 8 seconds, automatically enter the closing process, closing the gate KM2 is activated, the motor reversal, when the door moves to the door limit switch K4 position, the motor stops running. 3) In the process of closing, when someone from outside to inside or from inside to outside through the photoelectric detection switch K2 or K1, should immediately stop the door, and automatically enter the door open the program. 4) After 8 seconds of waiting time after the door is opened, if the person passes the photoelectric detection switch K2 or K1 from outside to inside or from inside to outside, it must be restarted for 8 seconds and then automatically enter the closing process to ensure that Personnel through the security. The overall wiring diagram of the program ladder hardware is required
