PLC Automatic Door Control System • System have 2 motion detectors (11,12) O The door will open when one of the sensors detect motion. O • System have 2 outputs(Q1,Q2) One responsible for opening the door ,the other for closing door. And gates will be needed to build a standard interlocking circuit (B2,B3):by this way only one output can be active at time. . 2-detecors: 13:kimit switch open and 14 limit switch close: o the final position of the door are detected by the limit switches 13 and 14 (NC contact) 0 when the door is open 13 limit switch changes the state from close to open. o when the door is close 14 limit switch changes the state from close to open • we will add a off-delay block; when the detectors area of the 2 motion detectors is free for min time the door will close again.
