Program description

•There exists a conveyor that has 16 stands and is moving to the right.

•Each time the conveyor moves one stand to the right, a pulse input enters X1.

•There is a sensor on the left end of the conveyor, and when a defective unit is placed on the conveyor, X00000 turns on.

X00000 (sensor input) and X00001 (conveyor movement) signals are as follows:

X00000

X00001

•As the conveyor moves to the right, the data is also shifted one bit at a time, and when data exits to the carry (on the right end of the conveyor), the (Y00100) solenoid valve turns on and rejects the defective unit.
