A brief introduction to the programmable logic controller

The Programmable Logic Controller (PLC) refers to industrial digital computers designed to control various manufacturing equipment such as industrial robots, escalators, power plants and assembly lines. These sophisticated tools are used to control production processes where reliable controls, flexible programming, and easy troubleshooting are extremely important.

The importance of industrial computers grows in applications where accuracy with zero error is critical. Initially, the automotive industry used computer-driven systems to replace cam timers and hard wire relays. Computer-controlled devices have become a vital part of industrial process control and factory automation

Unlike personal computers, the PLC can handle a hard industrial environment where temperature, humidity, dust, mechanical shocks and other hazards predominate. Manufacturers need a variety of equipment to produce products and end users.

Any equipment or device that produces something in an establishment must be organized in a time interval. For example, in the automotive industry there is a tool or a set of tools that works on the external paint of the car and the other is working on the parts of the engine. One of the functions of an industrial digital computer is to set the exact duration of the machines so that all processes can be perfectly harmonized.

Industrial computers were introduced in the 1960s, and before it manufacturers rely on cam timers, relays and other similar devices that simplify their manufacturing processes. They regulate a wide range of applications ranging from small production systems to large-scale processing plants. One advantage of PLC is:

  • Low Cost
  • Highest Flexibility and Integration [19659017] The central processing unit (CPU), memory and inputs and outputs are the three core industrial digital computers parts. Like the personal computer, the CPU is part of the brain as a computer, as it fulfills all communication, arithmetic, logic and memory operations. The memory component of the PLC works just like the PCs.

    As mentioned earlier, years of efficient work in the tough industrial environment makes it possible for PLCs to deviate from personal computers. The digital computer must be flexible and configurable. The 21st century process control expects functional flexibility, excellent performance, and a smaller form factor of the regulatory system.

    The rapid development of industrial automation technology has allowed manufacturers to produce high quality products in a cost-effective way and with large scales. Powerful industrial computers, robots, sensors, intelligent and automated tools for the present and future of modern industries. It would be difficult for industries to remain competitive in the future without incorporating modern industrial technologies
