What Are PLC Services?

  • What Are PLC Services?

You’ve likely heard of PLCs if you’re experienced or are involved in industrial automation. But what exactly are PLCs, and why are they so crucial in the automation process? These are the types of questions we often receive from our clients regularly at Keltour, which is why we’re here to answer some of your frequently asked inquiries, so you can have a better understanding of their significance in this industry.



What Are PLC Services?


Before answering some of the most frequently asked questions we receive, we first need to define what exactly PLC stands for. PLC stands for Programmable Logic Control, which is a type of industrialized computer that is responsible for controlling various functions, including inputs, outputs, and central processing units. They are commonly employed in production and manufacturing lines, plants, and other environments where automation is required. PLCs can come in a variety of sizes and shapes. At the same time, some PLCs can be tailored to suit various industrial tasks.



What are examples of PLCs? 

Believe it or not, PLCs are used in our everyday life whether we notice them or not. Here is a closer look at how PLCs are used often in our world:


  • Any type of conveyor belt, such as the ones at your local grocery store or the airport, for luggage transportation.
  • Automatic traffic signals. When the traffic lights turn from red to green to yellow, they do so because of PLC software.
  • Doors such as the ones found in the majority of commercial buildings use PLCs that allow you to hit a button and open the door automatically.
  • Roller coasters use PLCs to move the individual carts up the initial incline before it is dropped back down for the ride to begin.
  • Packaging and Labeling Systems in the food and beverage industry
  • Water Processing and purification, controlling valves and other processes
  • Transportation Systems, including escalators and elevators
  • Control systems for machines that rely on time and counting. 
  • Sensor inputs that control temperature and humidity levels in industrial workplaces. 
  • Mining Industries 
  • Water 
  • Utility 
  • Automotive 
  • Agriculture 
  • Pharmaceutical industry
  • Paper industries include newspapers, books, printing, and more.
  • Purging procedures controlled by PLCs in the oil and gas industries.
  • Automatic liquid filling systems across various industries.

What are the main components of PLC?

 A Programmable Logic Controller (PLC) typically consists of the following main components: 

  1. CPU (Central Processing Unit): This is the core of the PLC and is responsible for executing the program instructions and controlling the various I/O (Input/Output) devices connected to the system.
  2. Input/Output (I/O) Modules: These are used to interface the PLC with external devices such as sensors, actuators, and other control equipment.
  3. Power Supply: This provides power to the PLC and other components in the system.
  4. Memory: This stores the program code and data used by the PLC.
  5. Programming Terminal or Computer: This is used to program the PLC and can be a separate device or a computer with the appropriate software.
  6. Communication Ports: These allow the PLC to communicate over a network with other devices, such as computers or other PLCs, IOT Interface
  7. Expansion Modules: These add additional I/O points or more functions to the PLC, 

How does a PLC work? 

Simply put, a PLC is in charge of making decisions according to the input it obtains from a tool or device it controls. They employ a ladder logic computer language to allow technicians to create interactive circuit designs that can manage electromechanical systems. For example, the input is received by the device before the PLC conducts the modifications that have been programmed to perform.

Why is PLC used? 

There are several reasons and benefits that utilizing PLCs can provide you and your business. Here is a closer look at the advantages of industrial automation with PLCs:

  • increased dependability
  • Safety
  • Real time Tracking 
  • Able to work 365 days a year 24/7
  • Repeatability 
  • Reduced energy consumption
  • Space requirements are reduced.
  • increased user experience flexibility
  • You can handle various devices at the same time.
  • Increased machine connectivity and procedure automation
  • Manufacturing processes will be increased.
  • Reduced operational costs

What is the difference between PLC and automation? 

Programmable Logic Controllers (PLCs) and automation are related but different concepts, nonetheless. PLCs are electronic devices used to control and automate industrial and manufacturing processes. They are typically used in manufacturing, Oil, Gas,Water,,Mining,Agriculture and power generation industries to control and monitor equipment and processes.

Automation, on the other hand, refers to using technology to perform tasks without human intervention. For example, various technologies can achieve automation, including PLCs, robotics, and artificial intelligence (AI). So, when thinking about PLCs and automation, consider PLCs as a subsection of automation.
