Chapter 6, Problem 3P
Program Plan Intro
Ladder logic program:
The above ladder logic program includes three inputs namely, I/1, I/2 and I/3, three rungs namely, Rung 1, Rung 2 and Rung 3, two pilot lights namely, PL1 and PL2 and two outputs namely, O/9 and O/10.
Explanation of Solution
b.
Condition for unlatch rung 2:
- When the input I/3 is set as true or ON state, the unlatch rung 2 is termed as active or in true state...
Explanation of Solution
c.
Condition for rung 3:
- When the input O/9 in Rung 3 is set as zero or low, the rung 3 is termed as active.
- When the input I/3 in Rung 2 is set as true, the output of Rung 2 will be reset as zero...
Explanation of Solution
d.
State of Pilot Light PL1:
- The ON state of pilot light PL1 represents that the output bit O/9 is in high state.
- This can be occurred when the relay in latched state is set to the bit 1...
Explanation of Solution
e.
State of Pilot Light PL2:
- The ON state of pilot light PL2 represents that the input bit I/3 is true in Rung 2...
Explanation of Solution
f.
Pilot Light used when the power is restored:
AC power is removed and restored through the circuit, the relay retains to its original state, n...
Explanation of Solution
g.
Inputs required for unlatched state:
- The relay is in latched state and the inputs I/1, I/2 and I/3 are false.
- To convert the relay state from latched to unlatched,...
Explanation of Solution
h.
State of the relay:
- The Programmable Logic Controller (PLC) executes the instructions according to top to bottom approach.
- When the closed instructions at I/1, I/2 and I/3 are termed...

- Python - need help creating a python program that will sum the digits of a number entered by the user. For example if the user inputs the value 243 the program will output 9 because 2 + 4 + 3 = 9. The program should ask for a single integer from the user, it should then calculate the sum of all the digits of that number and output the result.arrow_forwardI need help with this in Python (with flowchart): Im creating a reverse guessing game. Then to choose a random number from 1 to 100 and the computer program will attempt to guess it, displaying the directions calculated or not. The guess will be displayed and the user will answer if it was correct or not. If correct, the game ends, if not then the computer asks if the guess was too high or too low. Finally inputting an answer and the computer generates a new guess within the proper range. Oh and to make sure the program doesnt guess outside of the ranges produced by the inputs of “too high” and “too low”. The program ending when the user guesses correctly or after the program takes 6 guesses. HELP ASAP!arrow_forwardI need help with this in Python (with flowchart): Im creating a reverse guessing game.
