Programmable Logic Controller (PLC)


9/13

A programmable logic controller (PLC) is a digital computerused for automation of electromechanical processes, such as

control of machinery on factory assembly lines, control of

amusement rides, or control of lighting fixtures.

How it works

Programming in PLC

In order to create or change a program, the following items areneeded:

PLC Programming Device Programming Software Connector Cable


10/13

Advantages

Cost effective for controlling complex systems. Flexible and can be reapplied to control other systems

quickly and easily. Computational abilities allow more sophisticated control. Trouble shooting aids make programming easier and reduce

downtime.

Reliable components make these likely to operate for yearsbefore failure.

Disadvantages

Too much work required in connecting wires.Difficulty with changes or replacements.Difficulty in finding errors; requiring skillful work force.

More about PLC

A PLC has many "input" terminals, through which it interprets"high" and "low" logical states from sensors and switches.

It also has many output terminals, through which it outputs "high"and "low" signals to power lights, solenoids, contactors, small

motors, and other devices lending themselves to on/off control.

Conclusion:

This project gave me an opportunity to work in an industrial

atmosphere and get involved in technical discussions. It alsohelped me to know different types of electronics components. This

practical knowledge which is necessary for engineering students

was imparted to me. I also got an insight into various Equipments

used in industry and basic concepts of technology.
