Objective 2- Bottle FillingSystem
Once the Start pushbutton is triggered, the process runs as follows:
- Conveyor moves (Y0 ON).
- When a bottle is in position (BP TRUE) ?
- Pause the conveyor (Y0 OFF),
- Open the output valve (Y1 ON).
- When the bottle is full (BF TRUE), Close the output valve (Y1OFF).
- 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
- Verify that the flowchart is designed according to thenarrative statement. Please ensure that the program meetthe requirement of marking scheme.
- Put all input devices in OFF state before starting to run theprogram.
