What is PLC ? And its Usage Areas

PLCs, which stands for "Programmable logic controller", play an important role especially in the production departments of factories. PLCs, which have the feature of increasing working efficiency, offer many advantages to their users. In this week's blog post we prepared as ILX Engineering, we will explain what PLCs are, their types and areas of use. We hope it will be a useful blog post for those who want to get detailed information about PLCs, we wish you a good read.


What is PLC?

PLC is a type of automation device used in processes such as production departments of factories or control of machines. PLCs, which have different types among themselves, are automation devices that increase production efficiency. This automation device, which provides an advantage in producing more and higher quality products in a short time, is among the indispensable products of the automation age. They help to minimize potential errors in production.


Information on Structure of PLC Systems

PLC systems basically consist of 4 different parts. In this part of our article, we will give information about the structure of PLC systems.


1. Central Processing Unit

The central processing unit can be described as the brain of PLC systems. As a matter of fact, all transactions made through PLC systems occur at this point. Two different PLCs can use separate microprocessors. However, since the operating systems are different, the results it gives may also differ from each other.


2. Memory Unit

The memory unit, as the name suggests, serves as the memory of PLC programs. Each PLC has its own programs and the programs in question are stored in the memory unit of the PLC. The data stored here is transmitted to the CPU. The memory of the memory unit can be rewritten and erased.


3. Entry Unit

These are the units where analog or digital signals coming from outside to PLC systems are detected.


4. Output Unit

The output unit in PLC systems is the part that converts the logic voltage voltage related to the output points calculated in the PLC into electrical signals suitable for driving control elements such as contactors, relays and solenoids in the controlled system.


Advantages of PLC Expansion Units

After giving general information about what PLCs are and their structure, we can also touch on details about the advantages of PLCs. We can list the main advantages that PLCs offer to their users as follows:

They are produced to be extremely resistant to electrical noises, temperature differences and mechanical impacts.

They reduce errors in production and increase production efficiency.

It offers advantages in terms of speed, safety, flexibility of use, product quality and number of personnel in production.

PLC expansion units can control most of the operations performed thanks to their digital or analog input / output modules.

In PLC expansion units, operations such as timing, counting, and sequencing are provided through the software. That's why they can quickly solve problems.

It also provides benefits to the business in the long run. It minimizes service costs due to few breakdowns.

PLC expansion units both take up less space and require less wiring. This increases the ease of use.


PLC Usage Purpose and Areas

PLC systems are automation systems developed for use in industrial areas. They are automation devices that provide control to their users at points such as timing, counting, storage, and arithmetic operation functions. PLC systems detect physical events, changes and movements by measuring them and reflect the results as a result of logical operations to the field. They are used to increase efficiency in control engineering. In addition to all these, the usage areas of PLCs are quite diverse. They are automation devices suitable for use in many automation systems. We can list the main usage areas of PLC as follows:

Manufacturing industry

Agriculture

Energy

Chemical industry

Ventilation and cooling facilities

Automotive

Cement industry

Textile industry

Elevator facilities

Lighting systems

Packaging and packaging facilities



PLC Prices

PLC systems are divided into many types among themselves. The features of the PLC system types may vary depending on the brand of the product. Therefore, the prices of PLC systems vary within certain intervals depending on the manufacturer and its type. We have come to the end of the blog post we prepared as ILX Engineering. Throughout the article, we tried to give information about what PLC systems are, what they do and other details. You can reach the types of PLC systems we offer for you via the relevant link. You can consult us for price information of PLCs that you think are suitable for you.
