What Is Industrial Automation?

Industrial automation is the use of advanced technology, control systems and machinery to streamline industrial tasks and processes with minimal human intervention, integrating machines, sensors and systems across manufacturing and supply chain operations.

Key Takeaways
  • Industrial automation uses control systems, machinery and software (PLCs, SCADA, robots) to run manufacturing and processing tasks with minimal human intervention.
  • It falls into three types, fixed, programmable and flexible automation, matched to production volume and product variety.
  • The core building blocks are PLCs, SCADA, HMIs, robots and cobots, plus sensors and conveyors, working together as one layered system.
  • Warehouse automation is a sub-set of industrial automation, focused on storing and moving finished goods rather than making them.

What is industrial automation?

Industrial automation is the use of advanced technology, control systems and machinery to streamline industrial tasks and processes with minimal human intervention. It is the integration of machines, sensors, and systems to automate manufacturing processes, supply chain operations, and other industrial tasks. From automotive assembly lines to food processing plants, industrial automation is the engine that powers modern production.

At its core, industrial automation replaces manual labour with automated systems that are faster, more consistent, and more reliable. This shift allows human workers to move from repetitive physical tasks to higher-value roles in management, decision-making, and system optimisation.

How does industrial automation work?

Industrial automation works through a layered system of hardware, software, and control technologies that work together to monitor, control, and optimise industrial processes.

The typical automation architecture follows a hierarchy:

How industrial automation works


This layered approach allows manufacturers to achieve real-time control, data visibility, and rapid response to changing conditions. The result is a production environment where machines communicate, adapt, and optimise themselves with minimal human input.
Field level

sensors, actuators, and machines collect data and perform physical actions.

Control level

Programmable Logic Controllers (PLCs) and other devices process data and execute control logic.

Supervisory level

SCADA systems monitor and manage the overall process.

Enterprise level

business systems (ERP, MES) integrate automation data with broader business operations.

Types of industrial automation

Industrial automation systems are typically classified into three main categories based on their flexibility and the volume of production they support.

Types of industrial automation


Fixed automation

Also known as "hard automation", it uses specialised equipment permanently configured for a single, repetitive operation. High production volume, low flexibility, high initial investment and low unit cost. Examples: automated assembly lines, transfer lines in automotive manufacturing, and dedicated machining systems. Ideal for mass production of identical products.

Programmable automation

Designed for batch production; the equipment can be reprogrammed to handle different products or tasks. Moderate flexibility, with changeover time between batches and a higher unit cost than fixed automation. Examples: CNC machine tools, industrial robots programmed for different tasks, and automated workstations.

Flexible automation

Also known as "soft automation", it extends programmable automation to allow rapid changeovers with minimal downtime. High flexibility, computer-controlled, and able to produce a mix of products simultaneously. Examples: flexible manufacturing systems (FMS), robotic workcells, and automated guided vehicle (AGV) systems.

Key components of industrial automation

Industrial automation relies on several core technologies that work together to control, monitor, and optimise production processes.

Key components of industrial automation


PLCs (Programmable Logic Controllers)

A ruggedised industrial computer that carries out the logic functions once handled by relays, switches and mechanical timers. PLCs focus on real-time control, executing logic that directly controls machines and processes, from conveyor systems to robotic cells.

SCADA (Supervisory Control and Data Acquisition)

Systems that control and monitor industrial processes, gathering data from PLCs and other devices to give a high-level view. Operators can monitor conditions in real time, adjust setpoints, respond to alarms, and analyse historical data.

HMIs (Human-Machine Interfaces)

The software and hardware that let operators interact with industrial systems, presenting data so they can monitor conditions, adjust setpoints and respond to alarms. HMIs, PLCs and SCADA work together as part of a layered system.

Robots and cobots

Industrial robots are typically floor-mounted and programmed for repetitive, high-speed, high-precision tasks such as material handling, welding, painting and assembly. Collaborative robots (cobots) work alongside operators and are safer and easier to program. MotionTech offers both for packaging, pick and place and material handling.

Sensors and conveyors

Sensors are the eyes and ears of automation, detecting position, temperature, pressure and proximity and feeding data back to control systems. Conveyor systems form the backbone of material handling, moving products between workstations, storage and shipping zones.

Industrial automation vs warehouse automation

Industrial automation and warehouse automation are closely related but serve different purposes.

Industrial automation is the broader category. It encompasses the automation of manufacturing processes, production lines, and industrial operations, including technologies like PLCs, SCADA, robotics, CNC machines, and process control systems. It focuses on transforming raw materials into finished products.

Warehouse automation is a subset of industrial automation. It focuses specifically on the storage, movement, and retrieval of finished goods, raw materials, and work-in-progress within a warehouse or distribution centre, including technologies like AS/RS, conveyor systems, AMRs, and warehouse control systems (WCS).
