What is a PLC?

Programmable logic Control : PLC

      It is a device that controls the operation of the machine or the work process. The internal microprocessor. The PLC is an important input and output that can be used. Sensors or switches. It is connected to the input. The output is used to control the operation of the target device or machine. We can create a circuit or a type of control by entering a command program into a PLC. It can also be used with other devices, such as barcode readers, printers. In addition to the PLC It can be used alone (Stand alone) and can connect multiple PLCs (Network) to control the operation of the system to be more effective, it is seen that the use of P LC is very flexible in many industrial plants. Switch to PLC.

 

Structure of PLC

        PLC is a computer hardware for use in industrial applications. PLC consists of a processor, memory module, data receiver. Transmission unit And a small PLC programmable unit. All PLC components are combined into one unit. If it is large, it can be classified into sub-components.

        PLC memory consists of RAM and ROM memory, RAM memory. The program is used to store the user program and data for the operation of the PLC. The ROM is used to store programs for use in the operation of the PLC according to the program of the user. ROM stands for Read Only Memory, can be programmed but not deleted. If not repaired.

         1.  RAM (Random Access Memory) This type of memory has a small battery to hold data when a power failure occurs. Reading and writing programs in RAM is very easy, so it is suitable for use in the trial period with frequent changes to the program.

         2.  EPEPROM (Erasable Programmable Read Only Memory). This EPROM memory requires special programming tools. Removing the program is done by using ultraviolet light or hot sun for a long time, there are advantages that the program will not be lost even if the power goes out. It is suitable for use without changing program.

         3.  EEPROM (Electrical Erasable Programmable Read Only Memory) This type of memory does not require special tools to write and delete programs. By using an electrical method like RAM, there is no need for a spare battery when the power goes out. Price is more expensive. It will also include good features of both RAM and EPROM.
