Program Plan Intro
Programmable Logic Controller (PLC):
- PLC is a specialized computer used in industrial segments to control machines and process.
- PLC is program that consists of a set of instructions which resembles the controlling functions needed to perform specific tasks.
- The function of PLC is similar to that of a relay and hence, in an industrial segment a relay is greatly replaced by a suitable PLC.
- When compared to general Personal Computer (PC), a PLC is available in small and tiny sizes.
- The basic architecture of a PLC consists of an input-output interface module and a small Central Processing Unit (CPU) that runs by controlling
programming language.

Create a PLC ladder logic diagram for an alarm that turns on when either A counts up to 10, or B counts down to 7.
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.
