Automation

Why is Industrial Automation Important for Businesses Today?

In the rapidly changing business world, having an automation system in industry is like arming a business with increased agility. Leading global organizations are pushing for Digital Transformation to enable businesses to adapt quickly to market demands. The importance of an automation system for businesses can be summarized into three main aspects:

1. Increasing Productivity: The system can work continuously without stopping, resulting in a significant increase in production volume.
2. Long-term Cost Reduction: Although the initial investment may seem high, reducing waste and labor costs will quickly lead to a return on investment.
3. Safety: Using automated systems in hazardous areas can greatly reduce accidents that could otherwise harm employees.

For factories in Thailand, especially those in the EEC where SCMA provides services, adopting automation systems also helps address the problem of skilled labor shortages.

Main Components of Industrial Automation Systems

A complete industrial automation system is like a human body with various organs working together systematically. PLCs are akin to the brain and SCADA HMIs are like the face and nervous system, comprising the following main components:

1. Sensors & Actuators - Senses and Muscles

• Sensors: Function as "eyes" and "ears," detecting physical values such as temperature, pressure, or position, then converting them into electrical signals to send to the controller. For example, process sensors from the ifm brand that SCMA specializes in.
• Actuators: Serve as "hands" or "muscles," transforming command signals into movement, such as motors, valves, or pneumatic cylinders.

2. Control Systems - Commanding Brain

This is the heart of an automation control system and includes:

• PLC (Programmable Logic Controller): Industrial computers designed for high durability, used to receive values from sensors, process according to conditions, and operate machinery. If you're wondering what a PLC is and how it works, read our in-depth article (recommended for further understanding).
• DCS (Distributed Control System): A decentralized control system commonly used in large factories with complex processes.

3. HMI & SCADA - Window to the System

• HMI (Human Machine Interface): Touchscreens attached to machines, allowing operators to command or view status immediately.
• SCADA (Supervisory Control and Data Acquisition): A large software system that collects real-time data from across the factory and displays it in a central control room, helping managers see an overview and make timely decisions.

4. Industrial Robotics

Mechanical arms that take over human work in tasks requiring high precision or beyond human strength, such as welding, assembly, or pick-and-place operations.

Types of Industrial Automation You Should Know About

Selecting the right type of automation for your production model is key to success. We categorize types of systems based on flexibility into 4 categories:

1. Fixed Automation (Fixed System)

A system designed to perform a single task only, not easily adjustable. Suitable for mass production of one product in large quantities, such as beverage manufacturing conveyor lines. The advantage is low unit cost but lacks flexibility.

2. Programmable Automation (Programmable System)

A system that can be adjusted by changing the program, suitable for batch or varied products with not too many changes. Each change may require time to reconfigure machines.

3. Flexible Automation (Flexible System)

This is an advanced version of programmable systems where product models can be changed quickly without stopping machinery. Suitable for high-mix, low-volume factories using CNC or smart robotic arms.

4. Integrated Automation (Integrated System)

The highest level of industrial automation involves connecting all the above systems under a single management system from computer-aided design (CAD/CAM), resource planning (ERP) to shipping. All data is linked, forming the foundation of a true Smart Factory.

Frequently Asked Questions

How is Industrial Automation Different from Robots?

A robot or mechanical arm is merely "part" of an industrial automation system, which encompasses sensors, controllers (PLCs), software, and communication networks working together to control production processes.

What are L1, L2, and L3 Automations?

This refers to the hierarchical structure of automation systems:

• L1 (Field Level): On-site equipment such as sensors, motors
• L2 (Control Level): Control systems like PLCs, DCS
• L3 (Supervisory Level): Supervisory and control systems like SCADA, HMIs

How Should SMEs Start with Automation?

No need to change the entire factory at once. Start from bottlenecks or areas of frequent errors first, such as installing sensors for data collection or using small-scale automation (Low Cost Automation) and gradually expand when seeing value.
