In the fierce competition of global industrial automation, Programmable Logic Controllers (PLCs), as the “brain” of industrial control systems, have their degree of localization directly affecting whether China’s intelligent manufacturing can truly take the initiative in development. The latest industry data shows that by 2025, domestic PLCs will not only establish a foothold in the small and medium-sized market but will also continue to break into high-end application fields, gradually reversing the long-standing competitive landscape dominated by foreign brands. This article will focus on five of the most representative companies in the current domestic PLC field, analyzing their rise and breakthrough paths from three dimensions: core technological capabilities, market penetration strategies, and future development challenges.
1
Inovance Technology: Leader in High-Performance Modular Design
Market Position
Over 20% market share in small PLCs, firmly in the first tier of domestic brands.
Technical Advantages
Full support for EtherCAT bus, focusing on high-performance modular architecture, compatible with multiple protocol communications.
Core Scenarios
New energy equipment, logistics automation, textile machinery.
Challenges
The product line for medium and large PLCs is not yet complete, high-end chips rely on imports, and core technology self-research needs to accelerate.
2
Delta: Benchmark for Full-Scene Coverage
Market Position15% market share, the preferred brand for small and medium manufacturing enterprises and the Southeast Asian market.Technical AdvantagesAH/AS/DVP series cover a wide range, supporting various industrial bus protocols, and a user-friendly programming environment.Core ScenariosPackaging machinery, food processing, general automation production lines.ChallengesThere is a gap in high-end functional modules (such as multi-axis motion control) compared to international giants, and adaptability to complex scenarios needs improvement.

Xinje Electric: Expert in Customized Solutions
Market Position12% market share, leading in the textile and packaging machinery sectors.Technical AdvantagesOutstanding deep customization capabilities, supporting multi-bus communication, providing “integrated hardware and software” solutions.Core ScenariosAerospace, CNC machine tools, environmental engineering.ChallengesLack of experience in large projects, the stability of complex systems needs further validation, and brand premium capability needs enhancement.
4
Infinova: Innovator of High-End Performance and Open Architecture
Market Position
Rapidly rising in the high-end PLC market in recent years, recognized in the industry for high performance and openness.
Technical Advantages
Its technical advantages stem from three core labels:100% independent research and development of hardware and software, advanced system integration architecture, and rapid customer response mechanisms.The company insists on a comprehensive independent research and development system from bottom-level hardware to upper-level software, holding 100% independent intellectual property rights; its self-developed ICS Studio fully integrated development platform completely eliminates dependence on the German Codesys platform, achieving highly flexible safety and controllability while leveraging advanced system integration architecture to fully exploit the performance potential of hardware-software collaborative optimization.
Core Scenarios
Intelligent equipment, semiconductor equipment, precision manufacturing.
Challenges
Brand awareness still needs to be improved, market channel construction needs to accelerate, facing strong competition from international brands in the high-end market.

Zhongkong Technology: The “Invisible Champion” of Process Industries
Market PositionBenchmark projects in the petrochemical and power industries, with the reliability of the G5Pro system leading the industry.Technical AdvantagesStrong integration capability of the industrial internet platform, the G5Pro system adapts to harsh environments such as high temperature and high pressure.Core ScenariosPetrochemical, oil field steam injection boilers, energy management.ChallengesWeak motion control functions, application scenarios concentrated in process industries, need to expand into discrete manufacturing fields.
Today’s domestic PLCs are no longer just a single identity of “follower.” On the road of technological upgrades, edge computing and AI algorithms are deeply integrated with PLCs, opening the door to intelligent control wider; in ecological construction, it has also shifted from simple “hardware replacement” to “full-scene solutions,” with the industrial chain becoming increasingly closely coordinated; moreover, in emerging fields such as new energy and semiconductors, they are quietly building technical barriers.
Each of the five major brands has its own expertise, firmly establishing itself in niche markets with differentiated strategies. Although there are still “barriers” to overcome, such as high-end chips and complex system stability, with policy support and market demand driving them, domestic PLCs are rapidly transitioning from “substitutes” to “leaders.”
It is certain that as these brands continue to exert their strength, the “self-controllable” confidence of Chinese intelligent manufacturing will become increasingly robust — the golden age of domestic PLCs has quietly begun.
