Why Industrial Automation and Control Systems Are Becoming the Backbone of Modern Industry

Industrial production is no longer defined only by machinery, labor, and output. It is increasingly being shaped by data, software, connectivity, and intelligent control. Across factories, energy facilities, pharmaceutical plants, oil refineries, and logistics-heavy industries, companies are rethinking how work gets done. At the center of that transformation is one of the most important industrial technology segments of the decade: Industrial Automation and Control Systems.

According to Renub Research, the Industrial Automation and Control Systems Market is projected to grow from US$ 210.83 billion in 2025 to US$ 466.29 billion by 2034, expanding at a CAGR of 9.22% from 2026 to 2034. That is not just a sign of industry growth—it is a sign of structural change across the global economy.

In practical terms, industrial automation is no longer something reserved for large, futuristic factories. It is becoming the operating model for modern industry.

What Industrial Automation and Control Systems Actually Do

Industrial Automation and Control Systems, often shortened to IACS, are the integrated hardware and software platforms used to monitor, automate, and control industrial processes with minimal human intervention. These systems include technologies such as programmable logic controllers (PLCs), supervisory control and data acquisition (SCADA), distributed control systems (DCS), human-machine interfaces (HMI), sensors, industrial communication networks, and intelligent controllers.

That may sound highly technical, but the business value is easy to understand.

These systems help manufacturers and operators:

Reduce manual errors

Improve production consistency

Monitor operations in real time

Detect equipment issues before failure

Increase throughput

Lower energy and maintenance costs

Improve worker and plant safety

In short, automation allows industrial businesses to produce more with greater accuracy and less waste.

That matters more than ever in an economy where downtime is expensive, supply chains are under pressure, and customers expect speed, quality, and reliability.

Why the Market Is Growing So Fast

The biggest reason behind the rapid expansion of this market is simple: industries can no longer afford inefficiency.

For years, many factories and industrial facilities relied on a mix of legacy equipment, isolated control systems, and manual decision-making. That model is now being replaced by a smarter one—where machines, sensors, software, and analytics work together in real time.

As described in the research material, several powerful trends are accelerating adoption, including industrial digitalization, demand for real-time monitoring, predictive maintenance, AI-driven analytics, robotics, and Industrial Internet of Things (IIoT) integration.

The shift is not just technological; it is strategic.

Companies are under pressure to:

Increase productivity without dramatically increasing labor costs

Improve resilience in volatile supply chains

Reduce equipment downtime

Meet sustainability and energy-efficiency targets

Compete in a market where speed and flexibility matter

Automation helps address all of those at once.

That is why the conversation around industrial automation has evolved. It is no longer “Should we automate?” It is increasingly “How fast can we modernize?”

The Rise of Open and Flexible Automation

One of the most important developments in the industry is the move away from rigid, proprietary systems and toward more open, software-defined automation architectures.

Historically, many industrial control environments were built around closed ecosystems. Once a company chose a vendor, it often became expensive and technically difficult to integrate tools from others. That limited flexibility and slowed innovation.

Today, the market is moving in the opposite direction.

Open and vendor-agnostic automation systems allow businesses to connect different devices, software platforms, and applications more easily. This gives manufacturers more freedom to scale, upgrade, and customize operations without being locked into a single provider.

That trend received a strong signal in April 2025, when Schneider Electric introduced its Open Automation Movement, emphasizing more accessible, software-driven, and vendor-neutral industrial automation. According to the supplied market material, this reflects a broader industry push toward interoperability, engineering efficiency, and long-term system resilience.

For businesses, that flexibility matters because the future of industrial operations will not be built around one device or one software suite. It will be built around ecosystems.

AI and Edge Intelligence Are Changing the Factory Floor

If open automation is changing how systems connect, artificial intelligence is changing how they think.

Modern automation is no longer limited to pre-programmed commands and repetitive control loops. Increasingly, industrial systems are being designed to interpret data, recognize patterns, predict outcomes, and optimize operations automatically.

That means factories can now do far more than simply run machines. They can anticipate problems, improve performance, and make near-instant operational decisions.

This is especially important in areas such as:

Predictive maintenance

Machine anomaly detection

Production optimization

Autonomous robotics

Smart logistics and mobility

Real-time process correction

The market data highlights a notable example from March 2025, when Oxa partnered with NVIDIA to advance industrial mobility automation using physical AI and photorealistic simulation. The significance of that move goes beyond autonomous systems—it reflects the increasing role of AI in training, testing, and optimizing industrial processes before they ever reach the physical environment.

This is where industrial automation becomes especially powerful. It does not just automate what people already do. It creates new ways of operating that were previously impossible.

Why Controllers, Networks, and Communication Chips Matter More Than Ever

A smart factory is only as effective as the infrastructure supporting it.

Behind every advanced automation system is a network of controllers, communication modules, and industrial-grade computing hardware that keeps everything synchronized. As industrial operations become faster and more connected, the need for low-latency, high-performance control systems grows sharply.

That is why demand is rising for advanced PLCs, industrial PCs, servo controls, motion systems, and industrial networking solutions.

A clear example came in November 2024, when GigaDevice launched its GD32H75E EtherCAT SubDevice Controller, designed for industrial PLCs, servo control, communication modules, and variable frequency drive applications. Innovations like this are essential because they improve synchronization, speed, and real-time communication across industrial systems.

This may not be the most glamorous side of the market, but it is one of the most important. Automation is only as effective as the infrastructure that powers it.

The Big Challenge: Automation Is Not Cheap

Despite the optimism, the industrial automation story is not without friction.

One of the biggest barriers to adoption is the high initial investment required to deploy advanced automation systems. Implementing PLCs, SCADA, DCS, robotics, sensors, analytics, cybersecurity layers, and modern industrial networking is expensive—especially for small and medium-sized companies.

And the cost is not only about hardware.

The real complexity often comes from integration.

Many industrial businesses still operate legacy equipment that was never designed to communicate with today’s software-defined, data-rich environments. Connecting old and new systems requires engineering expertise, careful planning, and ongoing maintenance.

As noted in the research material, automation rollouts often also require:

Infrastructure upgrades

Workforce retraining

Cybersecurity improvements

Operational redesign

Long-term service and maintenance investment

That is why many companies adopt automation in phases rather than all at once.

The good news is that even partial automation can deliver strong returns. But the reality remains: digital transformation in industry is rarely a plug-and-play process.

Cybersecurity Has Become a Core Industrial Issue

As industrial environments become more connected, they also become more vulnerable.

That is one of the defining tensions in the automation market.

The same connectivity that allows real-time visibility, remote operation, cloud analytics, and AI optimization also creates more opportunities for cyber threats. Industrial environments are especially sensitive because a cyberattack is not just a data problem—it can become a production, safety, and infrastructure problem.

The research highlights this as a major challenge, noting the growing risk of ransomware, unauthorized access, network disruption, and vulnerabilities in legacy systems that were not originally designed with modern cybersecurity standards in mind.

This is why cybersecurity is no longer a separate IT discussion. In industrial settings, it is now part of operational strategy.

The market is already responding. In July 2024, Nozomi Networks introduced Arc Embedded, a security sensor that can be embedded directly within Mitsubishi Electric PLCs, helping teams detect threats and improve operational resilience without disrupting existing networks.

That kind of embedded security is likely to become increasingly standard as automation ecosystems grow more complex.
