Question

Study the following PLC Logic Ladder and answer following questions How many input signals this program is processing? 2. 1. How many timers are used in this program? 3. Which bit' number is being examined for "Push Button 1"? 4. Which 'bit' number is being examined for "Limit Switch 1? 5. If you want to build this program in the lab, which terminal number of the PLC you should use to connect "Motor 1"? 6. If "Push Button 1" is pressed, what will happen to "Light 1" and "Motor 1" after 3 minutes? 7. If "Push Button 1" is pressed, what will happen to "Light 1 and "Motor 1" after 4 minutes? 8. Modify the program such that "Limit Switch 1" can stop "Motor 1" if actuated.

Explanation / Answer

1- This is processing only two input signals. Which are push button 1 and limit switch 1.

2-Two on delay timers are used here. T4.0 and T4.1.

3- Bit number 0 is examined in push button 1 as in PLC there are 8 input bits in a byte which are from 0 to 7. So here 1 is used which denote 0 in terms of bit.

4-For limit switch bit 1 used as 2 is written which denote 1 in terms of bit number.
