Question
Chapter 11, Problem 12P
Program Plan Intro
Count-Up (CTU) Counter:
- The CTU counter refers to an up counter
- This counter is used to count an event that occurs logically or externally and places that value in the counter’s accumulator.
- The accumulated value can even be maintained during false rung conditions and can be reset back to 0 using reset instruction.
Math functions:
The basic math functions performed by PLCs are as follows:
- Addition
- This function is used to add one piece of data to another.
- It is also called as ADD.
- Multiplication
- This function is used to multiply one piece of data by another.
- It is also called as MUL.

Draw a plc ladder diagram for blinking lights with start and stop button. Please help me with this. Thank you in advanced.
It will be drawn in the form of a PLC diagram and a solution will be reached.
ROBLEM:
Control 2 double acting cylinders using one push button for start and one push button for stop. The
repetitive cycle is as follows: Extend C1, after 5 seconds extend C2, after 5 seconds retract C1, after 5
seconds retract C2 All the process stops when the cycle repeats itself 5 times (counter) in a row. (Use
CTD counter)
I – Conduct the experiment with Codesys PLC module or online PLC simulator.
()
II- Simulate the process with I/O, and evaluate the outputs. ()
III- Make suitable connections for the pneumatic circuit and PLC, run the simulation and get the
output verified.
IV-Interpret the output of the PLC program with respect to its function.

- 5 lamps are lit at intervals of 2 seconds with the start button. When all 5 lamps are lit, it waits for 5 seconds and continues to light up with 2 second intervals from the 1st lamp. If sensor 1 is active while lamp 1 is on, lamp 3 will continue to operate as above, without lamp number 2 turning on. with stop buttonlamps will be turned off at any time.draw the plc ladder diagram accordingly.arrow_forwardWrite a Ladder Logic PLC program for each of the following scenarios. Label all contacts and coils in the PLC program. Scenario 1 Turn on a light when either one of two switches (I1, I2) is toggled on (construct an OR Gate). Turn on a second light when both switches (Same inputs I1, I2) are toggled on (construct an AND Gate). Turn on a third light when both switches (Same inputs I1, I2) are toggled off (construct a NOR Gate). Turn on a fourth light when either switch (Same inputs I1, I2) is toggled off (construct a NAND Gate). Print a copy of the program showing the construction of the four gate configurations. Also, submit a truth table for the four input configurations. Then modify your program so, only one light turns on at a time as you toggle the four truth table states.
