We all know that the industrial automation market is the thing that the industrial revolution brought. It is not something that happened overnight and today, but it lasts for decades, we can say even a century ago.
For instance, according to experts, by 2024 this particular market will increase by 20%, which means that it will exceed $5 billion, which is significant growth. That is the main reason why most companies and industries are searching for skilled people that will understand how to fix and maintain PLCs and automatic systems.
Nowadays, PLCs or Programmable Logic Controllers are an essential part of manufacturing and automation, and if you want to learn how to maintain, repair and program them, you will need appropriate training.
We recommend you to consider Allen Bradley PLC training because it will provide you exceptional knowledge on everything that will help you become certified technician and programmer.
However, let us start from the beginning:
What Is A Programmable Logic Controller?
A PLC or programmable logic controller is a conventional device used for automation and manufacturing which can easily program to perform various controlling functions for other devices.
The idea is to monitor the state of input devices and to make decisions based on the specific programs so that you can maintain the output devices too. For instance, PLC controls elevators as the mechanical system.
The programmer has to create a specific and defined program that will detect the floor as well as requests that users make by selecting the desired level. Most elevators feature PLCs as the programming, which is the most straightforward way to create a particular automatic machine that saves our lives every single day.
These devices are simple to program and install, and with most of them, you will get quick-release screw connections so that you can install output and input devices without any additional problem.
Editing involves program corrections, changes as well as loading procedures, and in most cases, it will happen in a matter of milliseconds. These systems are modular, which means that you can match and mix various output and input devices.
All of them feature main components such as memory, CPU, a method of programming, output and input interfaces and power supply. To learn more on programmable logic controllers and its history, you should click here.
Why Should We Use PLC Systems?
Since they are a standard solution for most automatic industries, you can find them in many manufacturers such as car wash, service, and food industries, batch mixing, traffic lights, elevators and many more. We use PLC for innumerable things that we are using on a daily basis.
We can differentiate four steps when it comes to PLC operations:
- Input scan – PLC will examine all input devices that you have connected, and the primary goal is to store the information in the memory so that you can analyze it afterward.
- Program scan – It will scan the user application problem as well as execute specific operations and instructions based on information that you have implemented inside.
- Internal diagnostics and communications – As soon as PLC finishes with the programming instruction, it can efficiently complete and perform numerous diagnostic communication tasks and function such as close communication with terminals and other systems that are important for a specific
- Output scan – At the very end, PLC will create an update on the outputs and start the entire cycle all over again.
As the programmer, you will write a specific program based on the instructions that you wish to add in its memory so that PLC could perform various output control signals for the process you want to achieve.
Have in mind that it features its language, which includes syntax, grammar, vocabulary that you have to use if you want to make it work properly. Everything starts with eh CPU, and that is a mandatory requirement that you will understand.
The most common and popular programming language for PLCs is ladder logic, which represents an advanced version of relay logic. It is a program that uses the graphical diagram as well as circuit diagrams that relay logic used before.
It is utterly graphical language, which is similar to circuits, and engineers could comprehend it easily. It uses specifying contact coils and closure types so that you can create an analog control, math function as well as timer operations and multiple counters among other things.

What Will Happen In The Future
Since we live in an information age filled with robots and automation, we can easily say that everything around us will function like that in the close future. It is everywhere around us from automated trains, driverless cars, to construction sites.
You should understand that PLC is still the best hardware that will become an integral part of automation. Therefore, the future will want more and more experts in this field, which is why you should start learning it before that happens.
If you want to become a technical with expertise on programmable logic controllers, you should learn how to maintain, repair, program and design its systems. It is vital to have experience in testing, programming, and de-bugging ladder logic programs. You will be able to achieve it by working with various simulations and by entering the course that will help you reach the perfection.
Have in mind that PLC is expensive hardware, and if you do not program it well, the result could create dangerous productivity conditions. That is why you should find various software online that will help you simulate the program before you implement it in the core of the controller.
That will help you understand mistakes before they become a reality, which will help you become a better programmer and you will understand how to control the program in case of a fault.
Getting PLC training will help you gain more knowledge on this particular part of manufacturing, and you can create possibilities that are more prosperous for the future so that you can rest assured all the way.
It is simple to start, but you need to have appropriate knowledge in specific parts such as programming, engineering and how systems work altogether. It is simple as that.
