The PLC controller power supply delivers the essential power (normally five volts DC) to the CPU and input and output units connect into the back-plane of the frame. The memory unit by electronic means stores the PLC controller programs with other retrievable numerical data. The central processing unit implements the programs and makes the decisions needed by the PLC to operate and communicate with other units. A computer unit can be distributed between two parts the central processing unit and the memory or storage unit. CPUs differ in handling speed and storage choices. A central processing unit, control system, and computer are all names used by different producers to signify a similar unit that performs similar tasks. The central processing unit of plc is constructed into a single element fixed PLC controller while modular frame categories normally usage a plug-in unit. Introduction to the Central Processing Unit (CPU) of PLC So let’s get started with an Introduction to the Central Processing Unit (CPU) of PLC. 
So in today’s article, we will discuss details about it. It is the core part of plc without it plc is nothing, as there is no control system then how other devices can works. Similarly CPU of plc control every function and circuitry of plc. From receiving a signal to sending or control and logic function.
It controls every activity of plc.ĬPU of plc is like a personal computer CPU, which controls all functions of a computer. In plc, it is like a brain it performs a function like human brain. CPU stands for the central processing unit. In today’s tutorial, I am going to explain to you about detailed article on Introduction to the Central Processing Unit (CPU) of PLC.
In last lecture, we discussed detailed articles on f eatures of different plc inputs and output modules. As you already know we have started a series of PLC articles.
