What Is PLC | Automation Training Institute In Tnagar

Industrial automation is the way to move forward in the 21st century. Industrial automation as the name suggests is the use of automated instruments such as robots and computers for managing different machines and handling process. Automation was introduced in the industry. With a view to increasing productivity as machines can work all round the clock. Now as the time has passed the perception of the industry has changed. Now automation increases the flexibility. And also the quality in the process of manufacturing.


Industrial automation majorly divided into two segments. Such as programmable logic controller (PLC) and supervisory control and data acquisition(SCADA)

What is PLC

Programmable Logic Controller is one of the major logic controller devices. It used as an industrial computer control system. This device continuously keeps a track about the state of input devices and makes decisions following the custom program controlling the state of input devices.

This logic controller device has the capabilities to greatly enhance almost any production line, process or machine function. The biggest benefit of using a PLC is the ability to change and replicate operations or process while collecting and communicating important information. The modular nature of the PLC system is another benefit making it more powerful. With this feature, you can use a variety of Input and Output devices to best suit your application requirements.

What is Inside a PLC

The CPU contains the internal programs that give commands to the PLC on how to perform the following functions:

  • Execute the control instructions from the user’s program.
  • Communicate with other devices- the Input and also the Output devices
  • Perform housekeeping activities such as communication and internal diagnosis, etc.

How does PLC Operate

There are four basic steps in the operations of a logic controller devices which continually takes place in a repeating loop. Such as

  • Program Scan
  • Input Scan
  • Output Scan
  • Housekeeping

Programming Languages used to program a PLC

The Ladder logic programming language one of the commonly used PLC programming language. Some of the other languages to program a PLC are:

  • Ladder Diagram (LD)
  • Structured Text (ST)
  • Function Block Diagram (FBD, etc.

There are a lot of other concepts and lessons to learn in a PLC other than these.
