Gate programming example with a mitsubishi plc

Post by alain972 » Mon Aug 10, 2009 9:47 am

I would like a sample of a program for a gate where you have three swith to open the gate x0, x1, x2. Two limit switch x3 and x4 to detect the gate is close or open and two photocell connected in series x5 to detect there is a car or a person to open the gate again if gate was closing at the time or to stay open. I have made a program but would like some input. My concern is i don't want the gate to close where their is a car or a person. What i noticed also if the contactor changing over to fast, the motor doesn't stop, it will not reverse ( i am using a single phase motor with a capacitor). I have put a timer in the program. The program work but if it can be made better i don't mind. :|
