W2.6 Service-Oriented Architecture as an Integrative Backbone for Cyber Physical Systems

Chair: Dr. Rolf Riemenschneider, Research Programme Officer, European Commission, DG for Communications Networks, Content & Technology

HORIZON 2020 brings several challenges to the domain of automation systems and factory applications. It is nowadays widely recognized that networked embedded control systems are an enabling form, the basis for the development of many innovative products and services in a multitude of industrial domains that support the core of European industry excellence and leadership. Several EU-funded FP7 projects have undertaken the challenge to tackle manufacturing aspects towards realizing the next generation of Service-oriented architectures (SOA) and future ICT-driven automation solutions in order to bring to the factory level the latest developments in the field of ICT solutions, including the deployment of SOAs using international (and many times open) standards (many times belonging to the W3C) such as DPWS, OPC-UA etc.
Additionally ARTEMIS has developed a vision and strategy to address the ever growing challenges in this embedded systems area, particularly the ubiquity of data enables by M2M communications and Internet of Things, that goes far beyond the scale and capability of today’s systems. The complexity of manufacturing systems will significantly increase: through the proliferation of sensor data, and richness of functions and services when linking physical systems to computing systems and back-end data bases. The design of these cyber physical systems must cope with the need to manage functional complexity and an increasing data volume together with real-time, reliability and sustainability constraints. Industry competition will be based on the ability to realize and validate next generation automation and control systems and to develop new functionality and value –added services that evolve from recent progress in SOA-based automation; these systems then are linked in to all kind of collaborative networks (including Internet) across supply chains and processes, such as the utilization of private and public clouds, where the ratio of technology Time to Market to Technology Time on Market is increasingly challenging.
The proposed session will present key results coming from a multitude of European projects, a vision on where we are heading and its impact, as well as key challenges and roadmaps for the future collaborative industrial systems and the domains they affect.

 Presentations & Speakers: 

  • Service-oriented Architecture: A world-wide adopted ICT-Paradigm towards Industrial Implementations of Cyber Physical Systems
    Prof. Armando Walter Colombo, Research Program Manager at Schneider Electric Automation GmbH and Director of Institute for Industrial Informatics, Automation and Robotics, University of Applied Sciences Emden-Leer

The future “Perfect Agile Factory” will enable monitoring, processing and control information flow in a cross-layer way. As such the different systems composing the whole enterprise will be part of a distributed ecosystem, where components, hardware and software, can dynamically be discovered, added or removed, and dynamically exchange information and collaborate. This cross-layer, intraenterprise collaborative infrastructure will be driven by business needs exposed and managed as individual and/or composed services by the system’s components.
In the presentation, an overview of key challenges appearing across the enterprise architecture will be addressed, such as structural, operational and managerial independence of the shop floor and enterprise constituent systems, interoperability, plug and play, self-adaptation, reliability, energy-awareness, high- level cross-layer integration and cooperation, event-propagation and –management, among others. The major characteristics and results of first industrial prototype implementations will be presented, describing the application of the Service-oriented Paradigm (SoA) to virtualise a shop floor and allow it to expose its capabilities and functionalities as “Services” located in a “Service Cloud”. 
Looking at latest reported Research-Development-Innovation-Results, two major trends and key enabling technologies and paradigms will be overviewed and the major characteristics of their potential use in industrial shop floors will be highlighted: “Cyber-Physical Systems” and the fusion between “Service-oriented Architecture and Cloud Computing”.

  • Implementing SoA in Industrial Cases: The SME Viewpoint
    Otto Karhumäki, Technology Director of Fluidhouse Oy

Adopting a Service-oriented Architecture (SoA) design approach in Industrial Automation Systems allows SMEs providers to enhance their business offering. In order to create new business opportunities, SMEs recognise the need to differentiate themselves by adopting a high-risk technology driven element such as SoA in Automation. Thanks to the current maturity of SoA design concepts, confidence among SMEs is becoming high. SoA approach deployed via Web Services is based on open standards and has been tried and tested in many different domains providing a cover for the technological adoption among SMEs.
This talk will provide some examples on how an SME like FluidHouse did develop and implement SoA- based monitor and control systems for their clients. It will stress the option for a stepwise approach to the implementations and also the main driven force of creating parallel solutions to the existing control systems, such as monitor and other applications.

Future factories are expected to be complex System of Systems (SoS) that will empower a new generation of today hardly realizable, or too costly to do so, applications and services. New sophisticated enterprise- wide monitoring and control approaches will be possible due to the prevalence of Cyber-Physical Systems (CPS), which have made Machine-to-Machine (M2M) interactions a key competitive advantage and market differentiator. This will be possible due to several disruptive advances, as well as the cross-domain fertilization of concepts and the amalgamation of IT-driven approaches in the traditional industrial automation systems. The Factory of the Future (FoF) will rely on a large ecosystem of systems where collaboration at large scale will take place. Additionally with the emergence of Cloud Computing, it is expected that Cyber-Physical Systems will harness its benefits, such as resource-flexibility, scalability, etc. and not only enhance their own functionality but also enable a much wider consumption of their own data and services. The result will be a highly dynamic flat information-driven infrastructure that will empower the rapid development of better and more efficient next generation industrial applications while in parallel satisfying the agility required by modern enterprises.

The Service-oriented Architecture (SoA) design concept is an evolution of previous approaches to warp and encapsulate data processing while the how and where the data is processed become transparent for the service consumer. The main advantages of SoA with respect to previous efforts reside on the well- established set of XML-based open standards for defining concepts such as: the description of the service, the communication among the services, and the discovering and connection between the services.
The automation of production systems is becoming a software-intensive task, and therefore, is facing even more integration issues to those already identified in the early 80s and 90s. It is expected than the deployment of SoA via different approaches such as DPWS (Device Profile for Web Services) or OPC-UA (OPC-Unified Architecture) at the Factory Floor will relax these integration tasks.
This talk will provide the views on how to capitalize Information Infrastructures deployed as SoA by creating a Factory InfoStore, which in a way reassembles the concepts of the Stores for Applications of the consumer electronics business. It will stress the possibilities for introducing new actors for the production automation business, and also the potential utilization of the concept by SMEs.

    Prof. Martin Wollschlaeger, Chair of Industrial Communications, Director of the Institute of Applied Computer Science, Faculty of Computer Science of TU Dresden

Service-oriented approaches are increasingly implemented in manufacturing systems. They are used in various levels of the manufacturing systems’ structure, ranging from sensor and actuator level up to MES and ERP. Within the EU FP7 project PLANTCockpit, this approach enables to extract manufacturing data from all these levels and to flexibly compute and combine them in order to generate and visualize aggregated data. This data are Key Performance Indicators (KPIs) that are used for enhancing production visibility, for energy management and sustainable manufacturing.

  • The ARTEMIS Innovation Pilot Project for Production and Energy Systems Automation
    Prof. Jerker Delsing, Professor at Lulea University of Technology, Coordinator of the Arrowhead project

Automation will in the future be built on services provided by systems and things all of the being networked. This puts high requirements on simple and seamless interoperability of services form different systems and things provided by any company. Arrowhead is addressing service interoperability by defining the Arrowhead service technology framework which will be proven in real application pilots in five technology domains, production, smart cities, electromobility, energy production and usage and the virtual market of energy. The service framework will provide core services for information infrastructure, system management and information assurance. Utilising the framework applications like railway train wide maintenance systems can be created supporting easy information tailoring to involved stakeholders.
