Objective: To detect and activate a conveyor belt that fills 8 Oz and/or 12 Oz soda cans and/or bottles. General Operation: FILLING STATION An OFF ON switch controls the operation of a conveyor and fill valve. There is a CAN_BOTTLE switch that determines whether a can or a bottle is being filled. Can are 8 Oz and bottles are 20 Oz. The soda can/bottles are packed as either 6 packs or 12 packs. Timers/counters will be used to time the operations of the fill cycle and count the number of cans or bottles that pass over the conveyor.

➤ System Operation: ● When the OFF_ON switch is OFF, the CONVEYOR and VALVE should immediately turn OFF and the number of cans/bottles and packs produced should be rest to zero. (You can use the RES instruction for this). If the CAN_BOTTLE switch is OFF, the process will fill 8 Oz cans of soda. If the CAN_BOTTLE switch is ON, the process will fill 20 Oz bottles of soda. 31 If the OFF_ON switch is turned ON, the conveyor should start and the following should occur: I The CONVEYOR should turn OFF when a can/bottle is detected, and remain OFF until the filling operation has been completed. (See hint below). 0.5 seconds after the PROXIMITY sensor signal has turned ON, the FILL VALVE should turn ON for 1.5 seconds to fill the 8 Oz can or 3.75 seconds to fill the 20 Oz bottle. 0.5 seconds after the can or bottle has been filled, the CONVEYOR should restart. If the 6_12_PACK switch is OFF, the process will count the number of 6-PACKS of soda so far produced. If the 6_12_PACK switch is ON, the process will count the number of 12-packs produced.
HINT: Do not use the latch/Unlatch instruction for the conveyor. Instead, use the Direct Coil instruction in a single rung, so that when the OFF_ON button is ON and the timer timing bits of all three timers to be used in the program are OFF, the CONVEYOR is ON. NOTE: In order to receive credit, your program should use the MOV instruction to establish how long the FILL valve should stay ON (1.5 or 3.75 seconds). The MOV instruction should also determine whether 6 or 12 cans/bottles should be counted per pack. In addition, use the MOV instruction to reset the accumulated value of the can and bottle counter to zero. (The RES instruction will not work in this case).
