Consider a control system for a bottle filling system that detects the position of a bottle via a limit switch than waits for 0.5 sec and then fills the bottle until a photodetector detects the filled condition of the bottle. After the bottle is filled, the buzzer sounds and the control program will again wait for 0.7 sec, before moving to the next bottle. Until the limit switch signals, the feed motor M1 runs while there are fixed rollers which carry the filled bottle. Motor M2 keeps running after the process has been started. The diagram of the system is shown in Fig 8(b). Enlist the inputs and outputs of the system. Then construct the ladder diagram and explain it.
