Since the concept of "Industry 4.0" was first coined at the Hannover Messe in Germany in 2011, the global manufacturing sector's aspiration for intelligent transformation has been ceaseless. Today, we have moved from initial conceptualization to the practical implementation of the deep integration of IT and OT (Operational Technology). The open automation technology demonstrated by Schneider Electric at the 2025 Shanghai Industrial Expo is not merely a technological leap; it is powerful evidence of the structural change currently underway across the global industrial system.
We must acknowledge that this transformation is fundamentally demand-driven, not just a spontaneously emerging tech trend.
Ending the "Black Box": The Constraints of Closed Architectures and Industry Pain Points
Global manufacturing faces a common "paradox of transformation": on one hand, there is an urgent need to enable flexible manufacturing through large-scale data utilization and AI model deployment; on the other hand, traditional industrial control systems-specifically the closed architectures based on PLCs and fieldbuses-have become the biggest impediment.
These legacy systems essentially operate as "black boxes":
- Data Silos: The tight coupling of hardware and software, along with incompatible protocols, means valuable production data is locked within devices or vendor-specific systems, preventing its efficient cross-domain utilization.
- Innovation Barriers: Control logic is deeply tied to proprietary hardware, making the integration and deployment of new algorithms and applications exceedingly slow and costly, severely hindering the speed of iteration.
- Computing Bottlenecks: Traditional controller architectures cannot handle the intensive computational demands of AI inference, preventing intelligent applications from penetrating real-time control loops at the shop floor level.
These "constraints" limit enterprises from achieving genuine "flexibility, collaboration, and efficiency," and impede the global supply chain's ability to respond quickly to change.
The Open Revolution: Software-Defined Control and the Path to Standardization
Open automation technology is characterized by a revolutionary "software-defined" restructuring of traditional industrial control. It no longer treats control logic as an auxiliary function of hardware but rather as a reusable, schedulable software asset.
Utilizing international standards like IEC 61499, control applications are decoupled from the underlying hardware, achieving:
Cross-Platform Portability: Control logic can be flexibly switched between industrial PCs, edge gateways, and real-time virtualization environments, significantly reducing system upgrade and maintenance costs.
Modular, Rapid Deployment: Complex control systems are broken down into standardized function blocks, allowing engineers to quickly integrate and deploy new production features, much like assembling building blocks, which dramatically boosts engineering efficiency.
This architectural shift opens a new channel for value creation in manufacturing, refocusing attention from one-time Capital Expenditures (CapEx) to continuous software services and innovation (OpEx).

Three-Dimensional Technology Synergy: The Foundation for the Future Factory's Determinism
For the open architecture to transition from concept to large-scale deployment, it must rely on the deep synergy of three critical technologies: networking, computing, and control:
1. Deterministic Networking: The Convergence of 5G and TSN
Achieving high-flexibility manufacturing requires solving the issue of communication real-time capability and determinism. By integrating the deterministic time scheduling capabilities of TSN (Time-Sensitive Networking) with the high bandwidth and wireless coverage advantages of 5G industrial private networks, industrial connectivity can move beyond reliance on traditional buses and extensive cabling. This not only enhances deployment flexibility but, more critically, provides a reliable technical guarantee for wireless networks to enter the real-time control loop for the first time.
2. Edge Intelligence: Front-Loading Cloud Computing Power
Modern factories require a "distributed brain." Non-real-time model training and large-scale data analysis remain in the cloud, while AI inference and rapid decision-making, which demand millisecond response times, are deployed on edge gateways and containerized platforms. This "cloud-edge-end" computing synergy mechanism ensures the stability and real-time performance of the control system while maximizing intelligent capabilities.
3. Ecosystem Collaboration: Breaking Down Barriers to Unleash Potential
The greatest significance of open automation lies in its creation of a multi-vendor, interoperable ecosystem.
Platform providers leverage open standards to attract system integrators,algorithm companies, and Independent Software Vendors (ISVs) to collaborate. This fundamentally resolves the problem of vendor lock-in for businesses. For Small and Medium Enterprises (SMEs), this means they can procure highly customized, industry-specific software functions and services at a lower threshold and in a more flexible manner, thereby accelerating the digital transformation of the entire industry.
Conclusion
Open automation is no longer just a technology option; it is a strategic prerequisite for global manufacturing to enhance supply chain resilience and achieve sustainable innovation in an era of rapid change. It is accelerating the industrial sector's transition from a closed, experience-driven era toward a fully open, collaborative, and algorithm-driven future.
