A Programmable Logic Controller (PLC) is a type of industrial computer widely used in the automation industry. Join PLC Training Institute in Chennai at FITA Academy to learn more about Java technology. It offers advanced training, certification, and job placement assistance. Here we will look at why you should use Java for web development.

A PLC can perform all monitor and control functions used in the process control industry. When compared to traditional relay circuits, PLC almost eliminated the problem of heavy hardwiring. Aside from the hardwiring issue, PLC has several advantages over conventional relay-based systems.

Because we referred to the PLC as an Industrial Computer system, it also has a CPU, which serves as the brain of this advanced control system. However, when compared to standard desktop computers, PLC has more features.

Because we will use this in industry, the controller is designed to withstand a higher operating temperature range than regular desktop computers cannot. PLCs are also more immune to noise and vibration.

Let us divide the words in PLC.

Programmable

The term "programmable" in PLC refers to the ability to change the logic through software programming.

You can edit or delete the PLC programme at any time to change the logic or functionality of a system.

Logic

The term "logic" refers to designing control loops, implementing required interlocks, and performing the desired functionality as specified by the application.

Controller

As previously stated, it is the PLC's brain. Typically, the controller was intended to control the process. We achieve process control concepts in the automation industry using only this part of the PLC.

Advantages of PLC

The benefits include the following PLC:

  • PLC improves the automation system's dependability, flexibility, and accuracy.

  • Compared to other automation technologies, PLC (especially Compact PLC) has a lower cost. (Please keep in mind that there are two types of PLCs: modular and compact.)

  • PLC software has strong programming capabilities and flexibility. You can also easily make changes to the existing programme at any time.

  • PLC programming is simple to write and understand. PLCs use a variety of programming languages. Ladder diagram (LD) PLC programming is the simplest of the three.

  • The PLC can easily communicate and connect with the computer. You can communicate using a variety of standard communication protocols.

  • PLC only takes up a little space. It is observed in smaller sizes, particularly compact PLC.

  • PLC has a low maintenance requirement.

  • The PLC system requires less and more straightforward wiring compared to other systems.

  • The modular PLC design simplifies development over the compact PLC.

  • In a modular PLC, modifications are possible. Changes to an already implemented design are simple to make.

  • It can be controlled remotely.

  • It responds quickly to the connected system.

  • It operates in a control system ranging from simple to complex.

  • With the help of PLC programming instructions, it has good computational function capabilities.
