Introduction to Mitsubishi PLC training

Mitsubishi Programmable Logic Controllers (PLCs) are essential components of industrial automation and control systems. PLCs are used to automate a variety of processes, from manufacturing and assembly lines to HVAC systems and traffic lights. Lyskills provides a complete introduction to Mitsubishi PLC training Course, covering fundamentals, hardware components, programming and practical applications.

Understanding Programmable Logic Controllers (PLCs)

What is a PLC?

A PLC or Programmable Logic Controller is a specialized industrial computer designed to control and monitor machines and processes. PLCs play a key role in automating tasks, ensuring reliability and increasing efficiency in industrial environments. They are known for their robustness, versatility and ability to withstand harsh environmental conditions.

Why use a PLC?

PLCs offer several advantages over traditional relay control systems. Some key benefits include:


PLC can be easily reprogrammed to adapt to changing production requirements.


PLCs are highly reliable and have a long life, reducing downtime in industrial operations.


PLCs simplify processes, optimize the use of resources and improve overall production efficiency.

Remote Monitoring:

PLCs enable remote monitoring and control, which is essential for managing complex industrial systems.


PLCs can implement safety features such as emergency stops and interlocks to protect workers and equipment.

Mitsubishi PLC hardware components

CPU (Central Processing Unit)

The CPU is the brain of the Mitsubishi PLC system. It processes instructions and controls various input and output devices. Mitsubishi offers a range of CPU models with different processing capabilities to meet the needs of different applications.

Input and output modules

Input modules are responsible for reading signals from sensors, switches and other devices. Output modules send signals to drives, motors and other output devices. Mitsubishi PLCs support different input and output modules to accommodate different signal types and voltage levels.


PLCs have memory to store program logic, data and system configuration. Memory is crucial to the operation of a PLC and is divided into three main types:

Program memory:

Stores the PLC program that defines the control logic.

Data memory:

Stores the variables and values used in the program.

System memory:

Contains system information and configuration settings.

Communication ports

Mitsubishi PLCs are equipped with communication ports to connect to other devices such as human machine interfaces (HMI), computers and network systems. These ports allow data exchange, remote monitoring and programming.

Mitsubishi PLC programming

Programming languages

Mitsubishi PLCs can be programmed using a variety of languages, with ladder logic being the most commonly used. Other languages include Structured Text (ST), Function Block Diagram (FBD), and Sequential Function Diagram (SFC). Ladder logic resembles electrical relay diagrams, making it intuitive for engineers and technicians.

Basic concepts of programming

Input and output instructions:

PLC programs consist of input and output instructions that control the flow of signals. Inputs are the conditions that trigger actions, while outputs are the actions themselves.

Timers and Counters:

PLCs support timers and counters to control time and count based operations.

Data Manipulation:

Programmers can create and manipulate data registers to store and process information.

Mathematical operations:

PLCs can perform mathematical calculations for more accurate process control.

Branching and Decision Making:

Conditional statements and branch instructions allow decision making within a program.

Programming tools

Mitsubishi provides software tools such as GX Works3 for PLC programming. These tools offer a user-friendly environment for writing, testing and debugging PLC code. Programmers can simulate PLC behavior to ensure correctness before deploying to real hardware.

Practical Applications of PLC Mitsubishi

Production automation

Mitsubishi PLCs are widely used in manufacturing automation. It controls assembly lines, robotic arms, conveyor systems and quality control processes. PLCs ensure consistent product quality and shorten production cycle times.

Building automation

In building automation, Mitsubishi PLCs control HVAC (heating, ventilation and air conditioning), lighting, security and access control systems. They increase energy efficiency, occupant comfort and safety in commercial and residential buildings.

Traffic control

PLCs play a key role in traffic control systems, traffic light control, pedestrian signals and vehicle detection. They optimize traffic flow, reduce congestion and increase road safety.

Water treatment and utilities

Mitsubishi PLCs are used in water treatment plants to control pumps, valves and chemical dosing systems. They ensure safe and effective treatment of water for consumption and industrial use.

Food and beverage industry

In the food and beverage industry, PLCs are used for process control, packaging and quality assurance. They monitor and regulate temperature, pressure and mixing during food production.


Mitsubishi PLC training is essential for professionals working in industrial automation and control systems. This introduction covers the fundamental aspects of Mitsubishi PLCs, including their hardware components, programming and practical applications. As technology continues to advance, PLCs remain a critical tool for improving efficiency, safety, and reliability in a variety of industries. Mastering a Mitsubishi PLC opens the door to exciting career opportunities in automation and control.
