Defining Automation: Scope and Key Principles
Industrial automation involves the application of control systems, machines, software, and other information technologies to manage manufacturing processes and industrial production. The aim is to reduce human operators and enhance the efficiency of production, product quality, system reliability, and minimize the cost and risk of production.
Automation in industry has developed from simple mechanization to more complex, digitally integrated systems, including the industrial automation system and automation solutions that power modern factories. It serves as the backbone of industrial automation technology and intelligent manufacturing processes.
Three Core Elements of Automation:
- Control System: Devices like PLC (Programmable Logic Controller) and DCS (Distributed Control System). They are the “brains” of the automation system, executing preset logic and instructions.
- Sensing and Feedback: Sensors monitor physical parameters (temperature, pressure, position) in real-time. This data is fed back to the control system to achieve closed-loop control.
- Actuation: Mechanisms responsible for converting control system commands into physical actions, such as motors, valves, and robots. They are the “limbs” of the automation system.
What is industrial automation? It isn’t just about replacing human labor; it’s precise, fast, and stable—features that human workers can’t match. It enables factories to operate 24/7, ensuring that every production batch meets high standards of consistent quality. As we enter Industry 4.0, automation is central to the digital transformation of industries, providing enterprises a competitive edge in the global marketplace.
The 4 Core Types of Industrial Automation
Automation in industries is not one technology. There have been four fundamental types, depending on the size of production batches, complexity of the product, and flexibility requirements. The companies need to select the appropriate type depending on the situation.
| Automation Type | Primary Characteristics | Key Applications | Advantages |
| 1. Fixed Automation (Hard Automation) | High-volume production; fixed sequence of operations; change is difficult/costly. | Automobile assembly; continuous petrochemical processes; assembly line tasks. | Extremely high production rates; lowest unit cost. |
| 2. Programmable Automation | Suitable for batch production; sequence of operation can be changed with reprogramming. | Electronics assembly; batch parts processing; multi-product filling. | Offers good flexibility; cost-effective for medium volumes. |
| 3. Flexible Automation (Soft Automation) | Enables quick product changeovers (between different products / different parts) without physical setup change or downtime. | Custom electronics; aerospace component manufacturing; highly varied production. | Very high flexibility; rapid response to market demand. |
| 4. Integrated Automation | Entire factory systems ($\text{OT}$ and $\text{IT}$) are interconnected; complete integration of information and control flow. | Smart factories; complex manufacturing industry systems; large logistics hubs. | Maximizes efficiency; top resource utilization; fast decision speed. |

- Equipment: Industrial PCs (panel or rack-mounted), running standard operating systems with specific industrial process control software.
- Communication: Industrial Ethernet (Gigabit LAN or WLAN), for high-speed data transmission.
- Control Level:
- Role: The system’s “brain,” executing automation programs in real-time.
- Equipment: Programmable Logic Controllers (PLCs) or Distributed Control Systems (DCS). PLCs have real-time computing capability and interface with multiple input/output devices.
- Communication: Fieldbus protocols (like CAN, Profinet) or specific wireless protocols.
- Field Level:
- Role: Interacts directly with the physical environment, performing measurements and actions.
- Equipment: Sensors (temperature, pressure, proximity, photoelectric) and Actuators (motors, solenoids, hydraulic/pneumatic cylinders, switches).
- Communication: Communicates with the PLC through a Field Bus or point-to-point connections for diagnostics and control.

- Digital Twin: With the development of a perfect digital copy of physical objects in the virtual environment, businesses can model, experiment, and streamline the whole production line prior to implementation. This saves a lot of risk and cost.
- Edge Computing: Data processing is brought nearer to the factory floor control systems, with ultra-low latency real-time control and decision-making. This is essential to high-performance automation systems.
- Human-Robot Collaboration (HRC): Cobots will become the norm. They operate in a safe environment with human workers, with human cognitive flexibility and machine strength and precision.
Automation in industries is moving towards the concept of machines performing predefined tasks to the concept of systems that learn and optimize themselves. This means that future automation elements must not only be reliable, but also highly connectable and able to process data, in order to be able to support the vision of Industry 5.0.
