1.2 Scaling Hot Data : An OPC UA Aggregator Use Case at Renault
„As factory operations increasingly demand „hot,“ sub-10-second data, Renault Group faced a major challenge: handling the growing number of OPC UA client requests on the shop floor without impacting our existing „cold data“ cloud pipeline. To address this, the OPC UA Aggregator provides a single entry point for real-time data. It protects underlying OPC UA servers by aggregating and preserving local data models, successfully unlocking a real-time shop floor OPC UA-based ecosystem.“
I fully agree with the presentation’s two main takeaways. For the Renault segment, I will highlight the OPC UA Aggregator’s critical role in scaling our real-time operations. Unlocking hot at scale is a major priority for the coming years, and this aggregator is what makes it possible.
The second point is equally crucial. The main differentiator of this aggregator – which we co-developed with Systerel – is that it actually replicates the address space of the aggregated servers.
At first glance, this architectural choice might seem counterintuitive or inefficient. Why not just use a standard passthrough like most OPC UA aggregators do? The reality is all about resilience. A passthrough model exposes local servers to client overload, which can disrupt critical cold data collection.
By replicating the address space, end clients query the aggregator directly. This acts as a shield, completely preserving the performance and functionality of the underlying servers. Three years ago, when we evaluated market vendors, almost none offered this replication logic. That’s exactly why we decided to build it ourselves.
Finally, regarding the presentation structure: I envisioned a two-part format to provide comprehensive feedback. Systerel will lead the technical dive on the Aggregator, followed by Renault demonstrating the deployment and practical applications. Please let me know if this aligns with your expectations, as I am fully open to rearranging the flow if necessary. Thank you in advance

1.3 Success Story: 6.5 Million Data Points – A Platform for Austria’s Road Infrastructure with evon XAMControl
How do you integrate millions of data points from tunnels, road facilities, and technical systems into a single, centrally controllable platform? In our project for ASFiNAG, we demonstrate exactly how this is achieved.
In this session, we provide insight into how we efficiently integrate all of Austria’s tunnel and road infrastructure into our evon XAMControl software platform via OPC UA. To achieve this, we developed our own ASFiNAG OPC UA specifications to establish a uniform standard for functionality and visualization.
In addition, we’ll outline the decision-making process behind selecting suitable communication protocols and explain the key reasons why OPC UA was ultimately chosen as the future-proof communication foundation.
Discover how standardization, structured integration, and modern communication technology are taking the control of critical infrastructure to a whole new level.

1.5 Moneytime: Bridging the Gap Between Shop-Floor Data and Enterprise ROI
While Industry 4.0 has successfully digitized physical assets through OPC UA, a critical financial blind spot remains between shop-floor events and their economic meaning. This presentation introduces the PPROI Framework and the concept of Moneytime, treating Capital Employed not as a static accounting value, but as a time-dependent variable linked to industrial process events. Based on microphase-level modeling, the approach applies a Financial Semantic Layer to transform raw machine and process data into real-time financial insight across assets, operations, and production lines. The session will show how inactivity, utilization, and hidden capital losses can be made visible within a Financial Digital Twin – and outlines how this concept could evolve toward an OPC UA Companion Specification for Financial Semantics.

1.6 OPC Foundation offering open-source solutions for the EU Digital Battery Passport
The Digital Battery Passport becomes mandatory in the EU in less than a year. In this talk, you learn about the Digital Battery Passport and the state of implementations. Since multiple implementations exists while the technical specification is not finalized, OPC Foundation’s Joint Working Group for Battery Solutions created the first Digital Battery Passport interoperability specifications to make different solution work together, based on the CENCENELEC JTC24 specification. The demonstration shows the automatic creation of Digital Battery Passports modelled with OPC UA and the flow of information from production but also during the live cycle and its integration to existing infrastructures.

Day 2 (May 19)
2.1 Certificate Lifecycle Management with Enterprise PKI and OPC UA GDS
As industrial systems become increasingly connected to enterprise IT, cloud platforms and IIoT ecosystems, securing machine identities is essential. Public Key Infrastructure (PKI) provides the foundation for trusted communication, but managing certificates at scale in OT environments is complex. This presentation explores how automated certificate lifecycle management using OPC UA Global Discovery Server (GDS) enables secure, scalable operations, and how OT PKI can be integrated with enterprise PKI systems.

Matthias Damm,

Operational technology (OT) environments are undergoing rapid transformation as industrial systems become increasingly connected to enterprise IT networks, cloud platforms and Industrial Internet of Things (IIoT) ecosystems. While this connectivity enables advanced use cases such as predictive maintenance, remote operations and data-driven optimisation, it also significantly expands the cyber attack surface.
A fundamental requirement for securing these environments is the establishment of trusted identities for machines, applications and services. Public Key Infrastructure (PKI) provides the cryptographic foundation for this trust by issuing digital certificates that enable authentication, encryption and data integrity. These certificates ensure that communication partners can be reliably verified before sensitive operational data is exchanged.
However, deploying PKI in OT environments presents unique challenges. Industrial systems often consist of large, heterogeneous device fleets with long lifecycles, limited connectivity and strict availability requirements. As a result, traditional manual approaches to certificate management are not scalable.
Automated certificate lifecycle management is therefore a key enabler for secure and efficient OT operations. It allows organisations to provision, renew and revoke certificates at scale while enforcing consistent security policies across distributed environments.
This presentation explores how certificate automation can be realised in industrial systems. It outlines the security mechanisms of OPC UA, explains the role of the Global Discovery Server (GDS) in enabling automated certificate lifecycle management, and demonstrates how OT PKI infrastructures can be integrated with enterprise PKI solutions to meet both operational and regulatory requirements.
2.2 Ensuring Authenticity with OPC UA
With growing security awareness, innovative concepts for trust-based device integration are highly important.
This presentation will examine how OPC UA provides a solution to ensure the verification of a device’s authenticity and its seamless commissioning, making it manageable for maintenance technicians. Furthermore, a comprehensive overview of the vital roles and processes across the device’s lifecycle will be provided.

2.3 Empowering OPC UA by Formal Semantics and Knowledge Graphs
OPC UA, the de facto foundation of the industrial data ecosystem, is now taking its next step: Formal Semantics.
With the restart of the OPC UA Semantic Validation Workgroup, the focus shifts toward making meaning explicit, machine‑verifiable, and interoperable beyond traditional system boundaries.
By building a bridge from OPC UA to the Semantic Web, we immediately unlock proven technologies such as Web Ontology Language (OWL) for logical constraints, SHapes Constraint Language (SHACL) for validation, and a query language (SPARQL). This bridge does more than validate models: It connects OPC UA to a global ecosystem of ontologies and knowledge graphs, enabling cross‑domain reasoning, integration with external knowledge, and new levels of interoperability.
This session introduces the foundations of Semantic Web and demonstrates its relevance for OPC UA. We will show how machine instances can be validated and how to semantically guard Companion Specifications through their lifecycle.

2.4 Early Detection, Reliable Integration: Verifying OPC UA Information Models with Confidence
This session introduces the Information Model Implementation Verifier, a tool for validating both OPC UA Information Models and the instantiated objects of an implementation. By checking structural and semantic correctness, it helps vendors and system integrators detect issues early and ensures consistent quality verification for any Information Model released by the OPC Foundation, even as specifications evolve.
With a strong focus on usability, the verifier requires only minimal connection input while hiding test complexity behind a streamlined workflow. It supports quality assurance across the entire project lifecycle—from prototyping and implementation to system testing and final commissioning—reducing integration risk and increasing conformance confidence. Built on the OPC Foundation’s UA Compliance Test Tool, it benefits from proven features such as CI integration, custom extensions, and a continuously evolving compliance testing framework.

2.9 AI Loves Python, Python Loves OPC UA
Artificial Intelligence (AI) and computer vision workloads are overwhelmingly developed in Python; not for raw execution speed, but because Python serves as an expressive orchestration layer on top of highly optimized C++ and Fortran implementations.
The new o6\Python OPC UA SDK embraces and extends this paradigm. By providing a Pythonic interface on top of the high-performance open62541 C stack, it enables efficient, low-overhead integration between AI pipelines and OPC UA-based industrial communication. The result is a seamless bridge between data-driven intelligence and real-time industrial systems.
A second dimension of “AI Loves Python, Python Loves OPC UA” emerges with the rise of Large Language Model (LLM) coding agents. These systems exhibit significantly stronger capabilities in Python than in C/C++. Combined with the rich type hints of o6\Python, they can generate comprehensive, correct, and maintainable OPC UA applications, thereby unlocking new levels of automation productivity in industrial software engineering.
Third, MCP-based architectures based on o6\Python enable ad-hoc question answering against dynamic OPC UA information models. This allows AI systems to interactively explore, query, and reason over live industrial data sources in a flexible and context-aware manner.
This talk demonstrates how aligning AI, Python, and OPC UA –augmented by LLMs and MCP – based interaction patterns-creates a powerful technology stack for intelligent industrial applications.

3.2 LoRaWAN to OPC UA – Reference Architecture and Case Study
This presentation is about a vendor-neutral architecture integrating LoRaWAN-based LPWAN sensor networks with OPC UA. It addresses challenges such as heterogeneous payloads, cloud-managed networks, and missing semantic standards. A data processing layer decodes, enriches, and maps raw sensor data into structured OPC UA information models. The solution supports OPC UA Companion Specifications and custom extensions for cross-industry applicability. MQTT integration enables both ingestion of external IoT data into OPC UA and OPC UA PubSub over MQTT. This ensures scalable, cloud-ready data exchange while preserving OPC UA semantics end-to-end. The architecture enables unified access to heterogeneous sensor data through a consistent interface. Optional analytics integration allows AI/ML-based insights such as anomaly detection and predictive metrics. Use cases include process industry applications leveraging PA-DIM® for standardized sensor representation. The approach provides a scalable, flexible pathway for integrating LPWAN data into industrial digital ecosystems.

Day 4 (May 21)
4.1 A new OPC UA Digital Twin framework and its show cases on OpenAtom competition including OPC UA WebAPI and AAS
After the release of the OPC UA WebAPI specification in 2024, we demonstrated this new standard by integrating it with existing OPC UA Servers at the OpenAtom Competition 2024. To further explore its potential, we contributed a Digital Twin Framework based on the OPC UA WebAPI standard on GitHub, including corresponding SDK and Tool Kits. Built upon the OPC UA Meta model and adopting the Asset Administration Shell (AAS) concept, this framework extends the OPC UA ecosystem from industrial devices to IT systems and the cloud, covering BOM, work orders, industrial knowledge bases, and more.
In the 2nd OpenAtom Competition held at the end of 2025, our teams successfully validated the concept and roadmap of this OPC UA Digital Twin Framework. We believe this represents a milestone and plays a fundamental role in supporting key areas such as industrial ontology and industrial AI.

4.2 Deeply Embedded OPC UA: Strategies for Full NS0 and Encryption on a $1 Microcontroller
Historically, OPC UA was perceived as resource-hungry compared to other communication frameworks such as Modbus and MQTT. We show this is not the case. OPC UA has a history on embedded devices. Different from previous efforts with feature-constrained implementations, we present strategies for a full OPC UA Server (NS0-Full, DI, encryption) on a $1 microcontroller, using less than 100 kB RAM. This opens new markets for OPC UA, including small sensors, smart building components, and even consumer devices.

4.3 From logistics to the European Green Deal – nothing works without automatic and unique object recognition! The AutoID industry has relied on OPC UA for more than 10 years.
AIDC technologies are among the core technologies required for automated manufacturing, the development of modern logistics systems, and the implementation of the European Green Deal. This makes the standardized, easy integration of these technologies –independent of specific technologies and manufacturers – all the more important. More than 10 years ago, the AIM Association and the OPC Foundation therefore developed a corresponding OPC UA Companion Specification. The need for standardized availability of basic information and technologies has not diminished since then. AIM has therefore recently contributed to standardizing the mapping of object coordinates using OPC UA semantics – it may sound trivial, but it is important.

4.4 From Automatic Asset Onboarding to AI-Orchestrated Manufacturing: An SDM Testbed for Industrial Deployment
This presentation is about an industrial testbed that repositions OPC UA as a foundation for AI-orchestrated manufacturing within Software-Defined Manufacturing (SDM). Moving beyond traditional data integration, OPC UA is used as a semantic backbone for capability-driven production coordination. The system enables automatic onboarding of assets across a pharmaceutical bottle production line in under five minutes, without PLC upgrades. Digital twins are seamlessly created by linking OPC UA companion specifications with Web of Things (WoT) interfaces.
This allows interoperable, reusable capability exposure across heterogeneous multi-vendor equipment. The architecture introduces AI-based orchestration using a MAGS (Multi-Agent Generative AI Systems) middleware layer. Machines expose capabilities via digital twins, enabling dynamic and autonomous production coordination. The implementation validates low-latency control APIs and automated semantic alignment across industrial models. It supports rapid production reconfiguration and service-oriented manufacturing approaches. Aligned with the OPC UA Cloud Reference Architecture, the solution enables scalable, multi-site AI-driven manufacturing.
