A conveyor motor has a N.O. START button (I:0/3) and a N.C. STOP button (I:0/4) to start and run the conveyor motor (O:0/4) when the START is pushed and released. When the conveyor is running bottles will pass a proximity sensor (I:0/2).  After 12 bottles have passed the sensor output O:0/5 must be turned ON (to have the bottles removed by a different machine) and the counter must be reset.  Sketch the program rungs to make this work.

Which statement out of the 5 is TRUE, Explain Why (50 Words) Pulse width modulation (PWM) can be used to control the speed of a DC motor. Whichstatement is correct?1. The ratio of the ON-times (supply voltage) and OFF-times (zero volt) send to theterminals of a DC motor is proportional to the average of the motor acceleration.2. PWM can be used to modulate the magnetic width of a brush-less AC motor.3. PWM modifies the pulses sent to a motor which in turn adjust the motor torqueproportionally to the pulse ratio.4. PWM can be used to adjust the average voltage delivered by a power source.This is achieved by rapidly switching the power signal on and off. Longer on-timescompared to the off times leads to a higher average power seen by the load, e.g., aDC motor.

1. A synchronous finite state machine contains a single 'Serial Data' input (SD) and two outputs (S and 7). Output S should be active for one clock pulse every time the input sequence 11010 is detected and output T should be active every time the input sequence 11001 is detected. The functionality of this machine may be partially represented by a timing diagram as shown in Figure 1. Clock a) SD S T Figure 1: Synchronous finite state machine timing diagram Derive the Moore model state diagram for this machine. Hint: ensure that the machine operates correctly even if the bit pattern is preceded by sub-sections of the pattern. [5]
