Everything You Don’t Know About PLC- A Common Industrial Technology
Thursday, March 22, 2018

PLC stands for programmable logic controller. It is a computer system that includes only a microprocessor but doesn’t come equipped with any keyboard, mouse or monitor.

It is built to basically stand through the coarse industrial environment. The word programmable itself establishes the system as being different from other traditional communication systems. It is also easy to alter and modify a PLC’s structure according to each application’s constraint. Since it doesn’t include any complex wiring, the PLC is generally free of any electrical hazards.

The programmable logic controller is especially designed for industrial purposes. It is assembled to stand through the harshness of its surroundings such as intense temperatures, dampness, noise and other common disruptions in the plants and factories.

PLC comes with several distinctive functions like sequential control and ease of programming. It also enables the users to accurately time and program the manufacturing operations. The system is also based on logic controllers that are responsible for controlling and scrutinizing a large capacity of sensors. These controllers are different from regular computer systems and have a more widespread input/output array.

Industrial Applications

The PLC is normally used in civil applications such as in manufacturing washing machines and also in controlling elevators and traffic lights. They are also seen monitoring and streamlining various production developments in several other industries. Some of its major applications can be found in the industries described below:

1. Paper Industry

In the paper industry, the programmed logic controllers are employed in several operations. They can be used for operating machines at a high speed to generate good quality paper. A more commercial application of PLC in paper manufacturing is to monitor the making of books and newspapers. This process supports the web printing of news right from its computer source to the paper form.

2. Glass Industry

The incorporation of PLC controllers in the glass industry ages back several decades. The machine is used to mainly control the ratio of material ordered, consumed and wasted to better evaluate the efficiency of the operations. The significant advancements in the technology over the years have widely increased its demand in the glass manufacturing industry, since the process of glass production is a sophisticated and intricate process.

3. Cement Industry

Cement manufacturing involves several different operations such as mixing different materials to form a desired type of cement blend. It is very important to appraise the quality of these materials and ensure that they are used in the appropriate proportions.

Both these factors greatly influence the ultimate product’s quality so special attention should be paid to them. The PLC system helps in automating and reforming the entire raw material acquiring stage and maintains an accurate range of data.

Apart from its use in the above industries, PLC programming is also used in the food industry for machine controls and in the aerospace sector, where the system is integrated for water tank equipments. PLC is also utilized in hospitals in the boiler fan system and for injection molding in the plastic manufacturing sector.
