Controller Modernization Is Becoming as Important as Greenfield Automation

Replacement and modernization are becoming major demand triggers as aging controllers across process plants, utilities, food production, automotive facilities, and infrastructure require migration without prolonged production shutdowns. Industrial controllers frequently remain in service for many years, particularly in process plants, utilities, food production, automotive facilities, and infrastructure applications where downtime is expensive and control architectures cannot be replaced casually. As installed systems age, manufacturers increasingly need migration paths that preserve production continuity while adding modern networking, safety, diagnostics, and data capabilities.

This creates a different commercial dynamic from automation markets dependent primarily on new factory construction. A mature manufacturing economy can continue generating meaningful PAC demand even with modest greenfield investment because existing production lines still require controller replacement, expansion, migration, and cybersecurity upgrades.

At the same time, manufacturers are asking controllers to handle more functions. Traditional PLC installations were often built around relatively distinct logic tasks. Current automation systems increasingly combine logic control with motion, synchronized machine operations, safety, visualization, condition data, industrial communications, and connectivity with higher-level software. This convergence favors programmable controllers capable of supporting multiple disciplines without creating unnecessary layers of hardware.

Emerson's PACSystems RX3i CPS400 Safety Controller, introduced in 2025, illustrates this transition. The controller was designed for SIL2 applications and supports a scalable architecture with as many as 2,000 available I/O points, targeting infrastructure, fire and gas, burner management, and emergency shutdown applications. Such product development shows that PAC suppliers are competing not merely on basic control execution but on safety, scalability, security, communications, and the ability to support complex industrial projects.

 

Modular/Rack-Based PACs Generate Disproportionate Commercial Value

Compact and integrated PACs dominated shipments in 2025 with approximately 1.70 million units, representing nearly 65% of PAC-equivalent controller volume. Their scale reflects widespread use in packaging machinery, production cells, material handling, electronics manufacturing, and medium-complexity automation, where machine builders need advanced control without large centralized architectures.

Compact PACs also reduce panel space while combining logic, communications, motion, and other control functions within standardized machine platforms. Expansion of modular machinery, flexible production cells, warehouse automation, and packaging lines should continue supporting unit demand.

Modular and rack-based PACs accounted for approximately 540,000 units in 2025 but carry greater value per system because they serve larger and more complex installations. Automotive lines, pharmaceutical plants, process industries, energy infrastructure, and water-treatment facilities require capabilities such as higher I/O capacity, redundancy, safety integration, deterministic communications, and greater processing power.

PC-based and software-defined control adds another architecture to the market. These platforms combine industrial control with edge processing and software applications, giving manufacturers more flexibility in allocating computing resources while complementing rather than immediately replacing dedicated PAC hardware.

 

Why Is Factory Automation the Largest Application?

Factory automation represented the largest PAC application in 2025, accounting for approximately 800,000 controller units. Demand spans automotive assembly, electronics and battery production, machine tools, component manufacturing, and automated production cells.

Industrial robotics provides a useful indicator of rising automation intensity. The International Federation of Robotics reported 603,000 industrial robot installations in 2025, up 11%, while the global operating stock exceeded 5.079 million units. Robot installations increased 10% in both automotive and electronics and 22% across metals and machinery.

Robots use dedicated controllers, but PACs perform a broader cell-level role by coordinating conveyors, fixtures, safety systems, inspection equipment, servo axes, and surrounding machinery. As factories connect more automated equipment, PAC demand increasingly comes from coordinating complete production cells and exchanging operating data across the plant rather than controlling individual machines alone.

Process automation accounted for approximately 400,000 PAC-equivalent units in 2025, with demand across oil & gas, chemicals, pharmaceuticals, food processing, utilities, and water treatment. Although volumes are lower than factory automation, requirements for redundancy, high availability, safety, and long operating life support higher-value controller configurations.

Motion-control applications represented roughly 380,000 units, supported by packaging machinery, machine tools, printing systems, electronics equipment, and material processing. Combining logic and synchronized motion within a common controller can simplify engineering and support more flexible machine designs.

Packaging automation adds demand from filling, sealing, labeling, cartoning, inspection, and palletizing systems. Food, beverage, pharmaceutical, personal-care, and consumer-goods manufacturers increasingly require rapid format changes, high throughput, and traceability, strengthening demand for controllers that coordinate multiple machine functions while connecting production data with plant-level systems.

 

Automotive, Machinery, and Electronics Form the Core End-User Base

The automotive and transportation industry used approximately 420,000 PAC-equivalent controller units in 2025, making it one of the largest individual end-user groups. Vehicle manufacturing requires control across stamping, body shops, welding, painting, powertrain assembly, battery production, final assembly, material handling, testing, and intralogistics. Electrification adds further automation requirements through battery-cell, module, pack, motor, inverter and associated component production.

Robot deployment provides evidence of the sector's automation intensity. In the United States, industrial robot installations increased to roughly 38,500 units in 2025, with automotive remaining the largest adopter. Food manufacturing also recorded strong automation growth, highlighting that sophisticated factory automation is spreading beyond historically robot-intensive industries.

Machinery and packaging manufacturers accounted for approximately 400,000 PAC-equivalent units in 2025. This segment is strategically important because machine builders act as an indirect route through which controllers reach thousands of downstream factories. Once a controller platform is designed into a standardized machine family, repeat production can generate recurring controller demand while creating an installed base that supports future replacements and upgrades.

Electronics and semiconductor end users represented approximately 300,000 units in 2025. Semiconductor production, electronics assembly, inspection, wafer handling, testing, precision motion, and related manufacturing operations depend on fast and highly coordinated automation. Omron's Industrial Automation Business highlights semiconductor investment linked to AI and data-center demand as one of the factors supporting future factory-automation activity. Its FY2024 Industrial Automation Business recorded JPY 360.8 billion in sales, with logic products representing 44% of its product sales composition, although that category includes products beyond PACs.

Food & beverage represented another major controller user, at approximately 300,000 units in 2025. The industry's large installed base of processing and packaging machinery creates demand across both new installations and modernization. Labor constraints, sanitation requirements, production traceability, rapid packaging changes, energy management, and the need to minimize downtime are increasing the commercial importance of automation.

Oil & gas, chemicals, pharmaceuticals and utilities contribute fewer units but typically require more demanding control architectures. Safety, long asset lives, regulatory requirements and continuous operation make lifecycle support and backward compatibility particularly important purchasing considerations.

 

Asia-Pacific Leads Volume, but Regional Demand Is Structurally Different

Asia-Pacific represented approximately 1.12 million PAC-equivalent controller units in 2025, making it the largest regional market by volume. The region benefits from its concentration of electronics, semiconductor, automotive, battery, machinery, consumer-product, and general manufacturing activity.

China remains the central volume market. IFR reported 354,000 industrial robot installations in China during 2025, representing 59% of global deployments. Domestic Chinese suppliers accounted for 55% of installations in their home market. Japan installed 36,219 robots, South Korea approximately 30,000, and India nearly 10,500. These figures demonstrate the scale and geographic diversity of automation investment across Asian manufacturing.

China's growing domestic automation ecosystem also changes competitive conditions. International controller suppliers must increasingly compete against domestic vendors capable of serving machine builders and manufacturing customers at different price points. This increases pressure around localization, software ecosystems, engineering support, industrial communications, and compatibility with locally preferred automation architectures.

India remains much smaller in absolute PAC demand but offers an expanding opportunity as automotive, electronics, machinery and industrial production scale. IFR reported that industrial robot installations in India rose 15% in 2025 to almost 10,500 units, while installations expanded at an average annual rate of 27% between 2020 and 2025. This progression supports a widening addressable base for controllers, motion systems and associated automation technologies.

North America represented approximately 580,000 PAC-equivalent units in 2025, supported by automotive, food & beverage, logistics, life sciences, oil & gas, semiconductor investment and manufacturing modernization. The United States remains particularly important because of its large installed controller base. As manufacturers add new equipment while maintaining older lines, compatibility and migration paths can strongly influence supplier retention.

Europe represented approximately 610,000 units in 2025. Germany is central to regional demand due to its machinery, automotive and industrial manufacturing base. IFR reported Germany as Europe's largest industrial robot market, with 26,982 installations in 2024. European manufacturers are also major producers of automation equipment, creating a mature market where replacement, machine exports, energy efficiency, and software integration can matter as much as construction of new production capacity.

 

Software-Defined Control Is Changing the Competitive Question

The next competitive phase will not be determined solely by controller processing capability. Manufacturers increasingly evaluate the entire engineering environment surrounding the controller: software tools, cybersecurity, interoperability, industrial Ethernet support, motion integration, simulation, remote maintenance, edge connectivity, and migration support.

This favors vendors capable of maintaining broad automation ecosystems. Mitsubishi Electric reported JPY 725.6 billion in FY2025 Factory Automation Systems revenue, covering control and drive products, processing machinery, power-distribution control equipment, and FA digital solutions. The scale of this broader ecosystem demonstrates how controller purchasing is increasingly connected to wider automation-platform decisions.

 

Competitive Landscape

The PAC market includes global automation suppliers such as Rockwell Automation, Schneider Electric, Siemens, Emerson, Mitsubishi Electric, Omron, ABB, Beckhoff Automation, Bosch Rexroth, Phoenix Contact, WAGO, Honeywell, Yokogawa Electric, and Advantech.

Competition increasingly extends beyond controller hardware to scalability, engineering efficiency, integrated motion and safety, industrial networking, cybersecurity, software openness, and lifecycle support. The ability to connect plant-floor control with higher-level digital systems is also becoming an important supplier differentiator.
