Objective 2- Bottle FillingSystem

Once the Start pushbutton is triggered, the process runs as follows:

1. Conveyor moves (Y0 ON).
2. When a bottle is in position (BP TRUE) ?
   1. Pause the conveyor (Y0 OFF),
   2. Open the output valve (Y1 ON).
3. When the bottle is full (BF TRUE), Close the output valve (Y1OFF).
4. Go to step (i) and repeat the process (with both BP and BFFALSE).

Once the Stop pushbutton is pressed, the process stops.

You are required todesign a ladder logic program to achieve the sequence stated in thenarrative statement above.

Hint: Start SwitchX0 (NO), Stop Switch X1 (NC), Sensor BP (use a NC switch torepresent), Sensor BF (use a NO switch to represent)

Please save the ladder diagram on PLC Fiddle and includethe URL link of the program

1. Verify that the flowchart is designed according to thenarrative statement. Please ensure that the program meetthe requirement of marking scheme.
2. Put all input devices in OFF state before starting to run theprogram.
