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.

Certification - Status of OPC UA FX certification

Because OPC UA FX will be used in real-time & safety-critical applications, OPC Foundation’s Field Level Communication (FLC) Initiative has decided to require mandatory certification for OPC UA FX products (i.e. controllers and field devices). Based on the OPC UA FX controller profile – specified in OPC 10000-84 – the FLC Test Development WG has created test cases and test scripts for the OPC UA Compliance Test Tool (CTT) in order to ensure that OPC UA FX products are compliant and interoperable with other products in machines, skids, factories and plants. This presentation will explain the concept and status to test the functionality of an OPC UA FX product, including the information model, the handling of UAFX connections as well as the offline descriptor.

Enterprise deployment of OPC UA in oil and gas brownfield assets using a data gateway and a domain specific information model

Aker BP has 7 offshore oil production sites, 6 brownfield and one green-field, using OPC UA and the same OPC UA information model that was made for Equinor’s Johan Sverdrup field, and was also open sourced by Equinor.

For the purpose of efficient workflow for normalization and enrichment of data from the various sites, an OPC UA gateway from TGS-Prediktor was chosen.

Aker BP calls this their Digital Foundation, which is an enabler from the strategic value perspective. A total of 1.2 million data variables is part of the solution. Among benefits are, enhanced data quality, robust change processes, information management within OT domain, standardized semantics across enterprise assets and reduced number of interfaces towards the cloud environment.

Base standard for Energy Consumption Management
„OPC UA for Energy Consumption Management“ has now been published under the number 34100. The standard is intended to serve as the basis for Companion Specifications that address energy consumption and standby management. It was created by a joint effort between the organizations ODVA, OPC Foundation, PI and VDMA. In terms of content, the specification describes energy measuring points for electric and not electric energy. Depending on requirements, these can also be implemented multiple times in systems, machines or components. In addition to displaying energy consumption values, the specification can also be used to perform standby management. Standby management enables a device or parts of a device to switch to an energy-saving mode when it is not in operation or activated.

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.

Day 4 (June 20)

Implementation of the NAMUR Open Architecture:
"One fits all" - one solution for all system architectures

The familiar concept of NAMUR Open Architecture opens up new possibilities for plant operators to optimize maintenance processes or increase productivity. Thanks to the standardized data model PA-DIM (Process Automation – Device Information Model) and OPC UA, the way up to higher-level asset management systems or other cloud applications has already been implemented. But how do we collect the data for existing infrastructure from the field level with as little impact as possible? The broad portfolio of different protocols, bus systems, manufacturers and field devices in existing plants in the process industry makes a „one fits all“ solution difficult to implement. However, different approaches can be used to map the information for all field devices in the systems. For example, for 4-20 mA devices, the HART protocol can be used to transmit and evaluate corresponding data in addition to the process values. Here, already installed signal splitters offer a quick and easy way to open a second channel. However, even without a signal splitter, a channel for monitoring and optimization can be implemented using the secondary master function of the HART protocol. It is estimated that 4-20 mA and HART cover between 60-80% of the field devices used. The remaining 20-40% is made up of Modbus, Profibus, WirelessHART and, in future, Ethernet-APL. NOA solutions are also required for these fieldbus systems and protocols. So do we need a special NOA device for every fieldbus system and protocol? Or are there possibilities for a flexible „one fits all“ solution?

A new digital tool for EU regulation - The Digital Product Passport under the new Ecodesign for Sustainable Product Regulation (ESPR)

The Ecodesign Regulation for Sustainable Products (ESPR) creates a horizontal product regulation for the European internal market.

It is intended to be the future main instrument for circular products in the European Union and therefore open the way to a circular economy.

The aim is to make sustainable products a standard. With the implementation of the Ecodesign Regulation, the scope of the original Ecodesign Directive has been greatly expanded.

Whereas previously only energy-related products were considered, it will also be possible to regulate many other product groups under the new Ecodesign Regulation.

When the regulation comes into force, information and reporting requirements will become mandatory.

In the context of digitalization, the digital product passport is now to be implemented as a tool for these reporting requirements.

The digital product passport is a collection of structured data with a predefined scope and defined property and access rights, which are transmitted via a unique identifier.

The content of this structured product data includes the components, materials and chemical substances used, as well as information on reparability, replaceability and professional disposal.

The data should originate from all phases of the product life cycle and should also be able to be used for various purposes in all these phases.


What does this mean for companies that fall under the corresponding product regulation?

What tasks will they have to fulfill?

Richard Merkel,
Introduction to the EU Battery Passport

AAS / DPP / PCF / DBP powered by OPC UA

OPC UA is a critical component to fulfill the requirements of the new EU legislation for the Digital Product Passport (DPP) as well as the Digital Battery Passport (DBP). With its vast ecosystem of modelling tools, best-in-class modelling capabilities and, in addition, the new REST interface that was recently added, OPC UA has all the ingredients to build DPPs and DBPs with ease. Product Carbon Footprint (PCF) data can be simply integrated from the shop floor and the supply chain. If you want to see how this works in practice, join the session!

Device and Update Management based on OPC UA Part 100: Devices

In the presentation, first the motivation for a holistic device and update management system is highlighted: High IT security requirements make it necessary for device firmware and certificates to be monitored and, if necessary, updated at a central location. Then, the basics of the software update model as an add-in of OPC UA Part 100: Devices are discussed. After that it will be shown how the software update model has been integrated into address spaces of Phoenic Contact PLCs and what the underlying process for distributing and executing software updates looks like. An application for holistic device and update management is then presented, with which the following features are realized:
– Updating device firmware
– Updating PLC projects
– Centralized creation, management and distribution of certificates
– Global discovery server

The integration of device and update management into the existing IT security infrastructure will also be discussed. The presentation concludes with an outlook that shows the future potentials of device and update management.

Using Companion Specification for Type based Client Application

In our talk, we will highlight the advantages of Companion Specifications, particularly from the view point of client developers. Companion Specifications are instrumental in defining domain-specific DataTypes, VariableTypes, and ObjectTypes, which can be used for the development of generic templates. We will demonstrate this concept’s effectiveness through the umati Dashboard, which utilizes such templates to integrate a diverse array of machines seamlessly.

Our methodology includes interpreting a Companion Specification’s model and adeptly mapping its nodes to visualization. The presentation will provide an exploration of the technical underpinnings, complemented by a demonstration of  the template generation process and the straightforward integration of machines into the dashboard.

A Query Language for OPC UA Event Filters

OPC UA Events are powerful but still underused in practice. This also stems from the effort of defining EventFilters.
Besides the selection of transmitted event fields, EventFilters also allow the definition of logical rules for server-side filtering of relevant events.This contribution proposes a query language to make OPC UA EventFilters more accessible. Examples are shown for a parser implementation as part of the open62541 library.

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.
