With the new SmartFactory reference architecture, SmartFactory Kaiserslautern (SFKL), Germany presents the foundation for intelligent, interoperable, and secure data networking of production, IT systems, and data spaces. The concept supports the goals of the national Manufacturing-X initiative.

The SmartFactory reference architecture implements the complete digitalization of production. "The spectrum ranges from edge-based, modular control technology to a unified IT data layer and agentic AI, while also addressing open data ecosystems," said Prof. Martin Ruskowski, one of the creators of the architectural model.

"Even the principle of the MX port from Manufacturing-X is already available as software with us. The individual elements interlock and ensure the future viability of the industry through faster engineering and optimized processes." A crucial contribution to IT/OT convergence.

Connecting Operational Technology (OT) And Information Technology (IT)

Industrial value creation is undergoing a profound transformation. Global crises, a shortage of skilled workers, and increasing regulatory requirements are putting additional pressure on companies. To ensure long-term competitiveness and innovative strength, fully connected, data-driven production systems are essential. This is where the reference architecture comes into play: it provides the technical foundation to seamlessly connect Operational Technology (OT) and Information Technology (IT) and to exchange data securely, interoperably, and independently of specific manufacturers.

"We are particularly addressing migration in the brownfield," emphasizes Simon Jungbluth, one of the authors of the recently published white paper 'SmartFactory Reference Architecture.' "We want to show that digitalization does not necessarily mean purchasing completely new systems but that even less complex algorithms can contribute significantly to optimization."

Digital Twin-Driven Manufacturing in Five Steps

"With the SmartFactory reference architecture, we demonstrate how factories can think and act in the future—connected, flexible, and intelligent," explains Ruskowski. "It serves as a practical guide for companies on their journey into a connected data economy. Of course, we offer all kinds of support through the community or via the SmartFactory Academy."

The path to a self-organizing factory based on digital twins is described in five steps. This allows companies to self-assess and formulate their own goals.

• 1. Create a digital foundation: Develop standardized data models and interfaces (e.g., Asset Administration Shell, OPC UA) for seamless communication and data availability.
• 2. Utilize data: Establish reliable data foundations for analyses and automated reporting to better understand processes and deviations.
• 3. Optimize processes: Derive concrete improvement measures from data analyses to increase efficiency and reduce costs.
• 4. Decentralized control: Introduction of digital agents for products and resources that autonomously exchange information and support decision-making.
• 5. Self-organization: Fully autonomous cooperation of agents, enabling the factory to respond flexibly, in real time, and adaptively to changes.

"The self-organizing factory does not emerge through a technological leap but through a deliberate, multi-stage transformation process," Ruskowski summarizes, emphasizing: "We are not saying that every factory ultimately needs to be self-organized. Companies know their own goals best. We just want to provide support on the way there."

Home of Next Gen Factory Automation

The three-layer model of the architecture—consisting of OT, IT/OT coupling, and IT levels—enables consistent integration of machines, edge devices, and cloud applications. Based on standardized technologies such as OPC UA, AutomationML, and the Asset Administration Shell (AAS), it establishes the foundation for interoperability, modularity, and secure data flows.

In addition, the application example of the production island _PHUKET demonstrates how these principles can be implemented in practice: smart machines control themselves, AI agents take over flexible production planning, and data is linked in real-time via standardized interfaces. "That's why we chose the slogan 'Home of Next Gen Factory Automation,'" says Jungbluth. "Because we are already applying these principles. We will showcase _PHUKET in November at the SPS trade fair in Nuremberg (Germany) at Harting's booth in Hall 10."

The reference architecture paves the way for data-driven services, AI applications, and new business models in the industry. Ultimately, companies should benefit through:

• Higher efficiency thanks to seamless data availability.
• Flexibility and resilience through modular, intelligent systems.
• Preservation of knowledge despite skilled labor shortages.
• Sustainable competitiveness in a platform-dominated market.

With the SmartFactory reference architecture, a robust foundation for the IT/OT transformation towards a connected, sovereign, and future-proof industry is available for the first time. (mk)
