No-Touch Scalable Containerized OPC UA Deployment
As the industrial landscape evolves toward decentralized, cloud-native architectures, OPC UA remains central to standardizing connectivity and interoperability. However, traditional OPC UA deployments—often static, Windows-bound, and tightly coupled to on-premise infrastructure—struggle to meet the demands of modern, dynamic, and distributed systems. In this presentation, we explore a visionary use case: a fully automated, no-touch, and scalable architecture for deploying OPC UA servers using containerization and lightweight orchestration.

OPC UA in vending industry
The European Vending & Coffee Service Association (EVA) is a not-for-profit trade association established in 1994, representing the interests of the whole European coffee service and vending industry vis-à-vis the European Union Institutions and other relevant authorities or bodies.
European Vending & Coffee Service Association and OPC Foundation started a Joint Working Group “OPC UA for Vending, Office Coffee Service & Automated Retail Working Group”.
This presentation is about to learn about the aim to develop an OPC UA Information Model for the communication between a vending machine, its peripherals, and the company’s information systems. A vending machine must be understood as a self-service machine that dispenses food (including drinks, such as coffee) and non-food products using different dispensing technologies.

Tobacco Companion Spec in praxis by PMI
While Philip Morris International Inc. is widely known as a cigarette company, in 2016 it announced its new purpose: To deliver a smoke-free future by focusing its resources on developing, scientifically substantiating, and responsibly commercializing smoke-free products that are less harmful than smoking, with the aim of completely replacing cigarettes as soon as possible.
To achieve this transformation, PMI has been expanding manufacturing capacity and diversity. There, the need to make manufacturing equipment digitally operational with speed and efficiency has never been greater; allowing faster ramp up of production, scaling and optimizing new manufacturing processes in a data driven way. Starting in 2017, PMI has been building a “digital foundation” based on OPC UA and the TMC (Tobacco Machine Communication) companion specification to exchange information in a structured, standardized and secure way with their manufacturing equipment. From simple data collection to advanced AI solutions, the standard has been a catalyst for the digital transformation of PMI’s shop floor.

Object Serialization: A new Core Technology for Data Streaming
Transmission of data from field level to internet clients gains more and more importance. There are already established core technologies supported by OPC UA for this purpose, such as PubSub. However, when dealing with object hierarchies containing different OPC UA variables at different hierarchy levels, a compact representation of the data of interest offers additional advantages for the consumer as well as for the publisher of the data. This paper explains the Object Serialization concept of aggregating values from different variables into the value of a single variable. It also explains how the inclusion of metadata and status information into this value can be customized for various use cases.

Role-Based Security Management for Industrial Devices and Applications Based on OPC UA
Open Platform Communications Unified Architecture (OPC UA, IEC 62541) has become a leading communication framework in industrial automation. OPC UA defines secure communication and information exchange that enable standardized connectivity between industrial applications in process monitoring, production control, manufacturing execution, etc.
In this paper we define a model for centralized security management for all industrial devices and applications, including user management and role-based access control (RBAC).
The aim is to present a model for managing application and user identities centrally with optional connections to existing IT network and user management systems via LDAP/AD connections.
The system also enables simple role-based access control (RBAC) based on roles defined in the central management system.
The roles can then be used in the server applications to limit access to critical functionality, such as controlling the devices, or even just to monitor their state.

Overview of activities and harmonization in the field of mechanical engineering
The mechanical and plant engineering industry is making great efforts to standardize machine data that is exchanged via interfaces. Over 60 OPC UA specifications have already been published in this area. At the heart of these standards is the OPC UA for Machinery specification. It forms the basis for all domain-specific specifications and can also be used without the use of other specifications.
In this presentation, the various activities and results of the numerous working groups will be presented. It will be shown for which machine types the standardization has already taken place or which areas are in the development process or are just starting. The presentation will focus on the OPC UA for Machinery standard, which serves as harmonization across the entire machinery and plant engineering sector. It consists of various published building blocks, each of which can be used to generate different added values.

OPC UA FX Automation Component - Ongoing work and future outlook
The FLC Base Facet WG is responsible for defining the common interfaces, behaviors and state machines of OPC UA FX automation components (i.e., controllers and devices).
The functional model of an OPC UA FX Automation Component consists of one or more Functional Entities, input/output variables and configuration parameters.
Information between multiple Functional Entities is exchanged by OPC UA FX connections. These connections are based on OPC UA PubSub and are established by a so-called Connection Manager which is a mandatory service of an OPC UA FX controller.
In this presentation an update is given which specification enhancements are being elaborated for Controller-to-Controller connectivity. In addition, an outlook is given how the Functional Model of an Automation Concept will be extended to support the connectivity between controllers and field devices, including field instruments, remote I/Os and motion devices.

Enhancing interoperability and engineering efficiency in Industry 4.0 environments
The increasing complexity of modern industrial automation systems necessitates efficient and standardized approaches for engineering and interoperability. OPC UA FX (Field eXchange) extends the OPC UA framework to enable deterministic, real-time communication across diverse industrial environments. AutomationML (AML) complements this by providing a standardized data format to represent engineering information across the lifecycle of automation systems. This paper explores the integration of OPC UA FX with AML to facilitate offline engineering processes. It outlines a methodology for using AML to model system components, communication structures, and configurations, which can be seamlessly imported into OPC UA FX environments. This offline engineering approach improves consistency, reduces manual configuration efforts, and enhances interoperability between engineering tools and runtime systems. The paper concludes by discussing future directions for enhancing interoperability and engineering efficiency in Industry 4.0 environments.

LADS OPC UA and Allotrope Foundation: Enabling Seamless, Interoperable Laboratory-Data Infrastructures
LADS is the OPC UA Companion Specification for the laboratory and analytical domain.
The Allotrope Foundation is an international consortium of pharmaceutical, biopharmaceutical, and other scientific research-intensive industries developing advanced data architectures to transform how laboratory data is acquired, exchanged, and managed across its full lifecycle..
Communication and data standards for laboratory and analytical applications are two sides of the same coin:
- Communication standards capture live data and results during experiments and analytical processes.
- Data standards document those results – along with the complete scientific context.
True data interoperability requires consistent definitions across both domains.
In this talk we demonstrate, how LADS OPC UA and Allotrope technologies create seamless integration – with Allotrope Foundation Ontologies providing the shared language.
This approach unlocks a scalable, semantically rich foundation for building the connected, digital lab of the future.

(LADS) OPC UA exposing Allotrope vendor-neutral data for BioPharma manufacturing or for standardized data access for automated offline laboratories
This presentation demonstrates how the unification of standardized lab instrument communication and harmonized, vendor-neutral data formats becomes a reality—by exposing Allotrope data model information as an OPC UA Information Model.
Such an approach is highly relevant in domains like BioPharma manufacturing, and it is increasingly important for the automation of offline analytical laboratories.
Mapping Allotrope data into an OPC UA Information Model enables the direct exposure of fine-grained information without the need to transport or parse the full ASM JSON.
The session will showcase a proof-of-concept that exposes Liquid Chromatography (LC) data—based on the Allotrope model—as an OPC UA Information Model, accessible via traditional OPC UA protocols as well as OPC UA REST APIs.
Whether you’re a lab equipment vendor, software provider, system integrator, or data scientist, this session illustrates how LADS OPC UA and Allotrope data models together pave the way for next-generation lab connectivity, streamlined workflows, and truly standardized, vendor-neutral data usability.

UAFX C2C Functionality for Robot Control Application
This paper delves into the use of OPC UA Pub/Sub over TSN in motion control applications, exploring its potential to factory floor to cloud communication capabilities. OPC UA, including C2C functionality via UAFX is employed as a real-time communication protocol, facilitating the exchange of data between controllers. Furthermore, OPC UA MQTT from the same stack is used to transmit data to the cloud for dashboarding purposes. This use case is implemented in a fully functional 6-Axis robot which is used in the packaging industry and supporting benchmarking measurements shows that the proposed design of OPC UA along with TSN is better performing compared to the legacy field-bus protocols. Also, the motion control application is always deterministic even after the convergence of IT and OT network
Key performance metrics, including round-trip time, network jitter, memory footprint, and system-level synchronization, are measured which supports that OPC UA Pub/Sub would be a right choice for filed level communication. Lessons learned from this solution development which include the importance of achieving faster cycle time communication in motion control applications through Pub/Sub over raw Ethernet frames, the ease of pushing motor control service data to the cloud and performing edge AIoT analytics is discussed in this paper.

OPC UA Information Model Management and Unified Name Spaces
The paper investigates how Industrial IoT solution architectures can be designed to create Unified Name Spaces with the help of OPC UA Information models. The paper is based on two customer projects. (cloud-based IoT solutions across 100+ production sites; one customer process industry, another customer food & beverage, both projects still in PoC phase). To enable efficient IoT application development, the customers need to work with a central data repository as „single source of truth“. The paper proposes a solution architecture with central governance for OPC UA information models to be deployed on edge level, thus creating standardized OT-interfaces publishing machine data into a Unified Name Space.
