 What is PLC? How PLC works, PLC is discussed in detail.

The full name of PLC (PLC) is:

Programmable Logic Controller.

This is a device that can easily control other instruments. This is a type of industrial computer control system. Which will make a decision as soon as there is any signal in the input, it depends on the custom program and control the output. PLC is usually composed of microprocessor that has to program with the help of computers. The program is basically to be written in computer software and is loaded in the PLC with the help of cable.

What is PLC. 

Where is PLC used?

We know that PLC is a digital computer that is used to control the necessary equipment in different factories. Any machine is used in the field of automation, nuclear power generation plant, chemical industry, automatic industry, home automation, cement, food factory, biomedical, Know's production and control, etc.

Brand Name of PLC:

Currently in the PLC market of different companies. However, some of these are known along with the PLC list.

1) Delta PLC (Delta

2) Ellen Bradley (Allen Bradley)

3) Mittabishi (Mitsubishi)

4) Fuji (fuzzy)

5) Penasanic (Panasonic)

6) Omaron (Omron)

7) LS (LS)

6) Toshiba (Toshiba)

9) Cement (Siemens)

10) Ftek (Fatek)

11) Straight (Schneider)

How does PLC work?

The PLC is the base control system of a type of microcontroller. It has a program memory that has a different types of inspection store. Through this, the first step input signal that will be given through Arithmetic (Mathematical) Lological, SiKuwaiti, timing, etc. is performed. This can easily control other devices.

PLC three main section

1) Power supply

2) Inpun output

3) Central Processing Unit

1) Power supply:

It must have a power to activate the PLC. The work of the power supply is mainly to input, CPU and output to provide necessary electricity. One more thing, there must be earthing in it. If you do not earthing, the program may not run properly, even if it is likely to be deleted.

In the case of different PLC, the required power can be more. There are many PLC who need 240 volts AC/DC from 115 volts to operate. Again there are many PLC only DC can be operated on 24 volts.

2) Input:

A variety of information is provided here. Information on the input device was sent to different parts of the output device according to the leder diagram. Input usually sends various types of switches, censors, temperatures, information, vultures, etc., to the center.

3) Output:

The information that came from the Central Processing is sent to the machine through the switch and the machine works accordingly.

Central Processing Unit:

Information that comes from input is sent to different parts of the output device according to the leather diagram. Also, some information of your own information can be connected according to the CPU diagram with the information provided by the input device.

PLC programming software:

First you need to make sure which brand of PLC will you use. A brand of PLC has to be used different software for PLC software.

PLC CPU:

You can increase the external input output if you want at PLC CPUL. Suppose you can use 36 inputs and 24 output, but your input and output will take more, then you can add the external module and output and it is very simple. Extension is possible in the PLC of the only modular. That is, a company has been PLC and the other is the madullah PLC.

Communication Cable:

It is better to use good quality cable and converters for PLC. Because there are different cables in the market that do not work properly. For this reason, PLC communication cable PLC should be taken from the company of that company. Although the price of the cables is much higher.
