SPS/IPC DRIVES International Workshop summary

SESSION: Communications

Martin Müller, Interbus Club Deutschland e.V., Blomberg, Germany (Chairman)
Prof. Dr. Christian Diedrich, Ifak Institut für Automation & Kommunikation e.V., Barleben, Germany

09:00The Impact of Ethernet on Industrial Communications

John Morse, Industrial Automation, IMS Research, Wellingborough, UK

The use of Ethernet in the industrial environment is one of the most significant developments in industrial automation. For a number of years IMS Research has carried out research work into industrial networking and industrial Ethernet markets. The presentation will examine the different protocols based on Ethernet, Ethernet infrastructure components and Ethernet enabled devices in the industrial environment. A general market synopsis, statistics and forecast trends will be included in the presentation.

09:30Net Diagnosis for Profinet IO

Frank Iwanitz, IAP, Softing AG, Haar, Germany

Today, dedicated monitoring applications are used for network analysis in fieldbus systems. These applications are utilized to identify implementation problems in devices, to commission applications including communication optimization, to locate sporadic disturbances in running applications, and to monitor the status of the production process and automation devices as part of permanent diagnosis solutions. In the future, today's fieldbus systems will be complemented and finally replaced by Real-Time Ethernet solutions. The proposed approach combines state-based diagnosis with an active monitoring component.

10:00 IO Link Communication at the Lowest Field Level

Christian Gemke, PHOENIX CONTACT GmbH & Co. KG, Blomberg, Germany

The communication to distributed I/O devices such as I/O stations is state of the art technology. However, the proprietary implementation of the communication interfaces to sensors and actuators does not fulfill the demand for a seamless communication and parameter data storage or a standardized tooling. The missing communication interface is an innovation obstacle for the sensor/actuator world.

SESSION: Engineering - Real Time Requirements and Drives

Prof. Dr. Georg Frey, Universität Kaiserslautern, Kaiserslautern, Germany (chairman)

11:00Supporting the Design of Drive Applications for Packaging Machines

Sebastian Diehm, ELAU AG, Marktheidenfeld, Germany

Engineering tools that handle increased requirements of mechatronic packaging machines contribute to lowering engineering costs. One of the most complex tasks in this case is motion design. Previously, this required complicated and time-consuming procedures. Tools such as ECAM-4 provide an approach to performing motion design more comfortably. Secondary tasks are automated, leading to high-quality results and reduced time requirements.

11:30 IPC based Closed Loop Control of Decentralized Servo Drives with eXtreme Fast Control (EtherCAT XFC)

Prof. Dr. Jens Onno Krah, University of applied science Cologne, Germany

In this contribution a new FPGA based Servo Drive concept is presented, where the position loop and the velocity loop are closed in an IPC-based PLC. Using EtherCAT as an extremely fast Fieldbus and an Embedded PC with Floating-Point-Unit (FPU), a Motion Control system with centralized feedback control can be built as open system. To customize Servo Loops there will be no need for interaction with a Servo Drive manufacturer any more.

12:00 Integrating Real-Time Ethernet in Injection Molding Machine

Werner Faulhaber, ARBURG GMBH + Co KG, Loburg, Germany

The injection process requires an extremely close linking of measurement values such as axis positions, speed/rpm, pressure/force and temperatures, etc. These values must be read and processed in each cycle within just 100µs. The number of axes to be controlled is limited. Expanded with an integrated robot system, a maximum of 16 axes are usually employed which must be coordinated in hard real time. What specific selection criteria were applied to achieve the right real-time Ethernet system for injection molding machines and what compromises had to be made?

SESSION: Engineering – Modularity and Reuse

Prof. Dr. Birgit Vogel-Heuser, University Kassel, Kassel, Germany (Chairwoman)

14:00Flexible Control Systems Development and Integration Environment for Distributed Systems

Prof. Dr. Haydn Thompson, University of Sheffield, UK

Development of distributed control systems requires tools that can deal with high complexity, integration of design information from multiple domains and analysis support for the overall design covering both technical and commercial performance. Currently, no integrated set of multidisciplinary design tools exist that can do this. The FLEXICON project created a toolset for Marine, Automotive and Aerospace (MAA) applications and this paper describes the application of the FLEXICON MAA co-simulation toolset to a Rolls-Royce High Speed Ship Demonstrator.

14:30Modularity in Machinery

Marcus Finkbeiner, Baumüller Nuremberg GmbH, Nuremberg, Germany

By making machinery modular, machine builders benefit from greater flexibility as regards the further development of their existing systems. Having a distributed configuration essentially makes it possible to break the machinery down into mechatronic units that can be logically mapped by means of software templates. One of the primary causes of major problems (from all kinds of perspectives) is the process of mapping the modularity within the software.

15:00Programming PLCs with an Object Oriented Approach

Dr. Ulf Schünemann, 3S-smart Software Solutions GmbH, Kempten, Germany

The IEC 61131-3 has established itself as a standard in programming of industrial controllers. Today more than 90% of all larger software projects for PCs use object oriented programming languages or methods. Despite scepticism about the benefit during the introduction period, shorter development cycle times and better re-usability have long been proven. These benefits are increasingly sought by the developers of larger control application projects.

SESSION: Engineering Along the Life Cycle

Prof. Dr. Haydn Thompson, University of Sheffield, UK {Chairman)

16:00Service-Oriented Cross-Layer Infrastructure for Distributed Smart Embedded Systems (SOCRADES)

Prof. Dr. Robert Harrison, Loughborough University, UK

16:30 Automatic Re-Implementation of PLC Programs

Dr. Mohammed Bani Younis, Helmut Schmidt University, Hamburg, Germany

Programmable Logic Controllers (PLCs) are a special type of computers used in industrial and safety-critical applications and re-implementation of an existing PLC program on a new platform requires considerable manual re-working by a specialist. Support for re-implementation on a new platform is rather limited today and is not fully automatic. The re-implementation process is especially complex whenever programs written in low-level languages such as Instruction List (IL) are to be re-implemented.

17:00SiSteMa: a Tool for the Simple Implementation of the Control Standard EN ISO 13849-1

Dr. Michael Huelke, BGIA - Institut für Arbeitschutz der Deutschen Gesetzlichen Unfallversicherung, Sankt Augustin, Germany

The EN ISO 13849-1:2006, the revision of the standard formerly known as EN 954-1, gives guidelines to develop, validate and certify in a simple way safety-related control systems in the field of machinery. SiSteMa makes it possible to design the structure of the safety related parts on the basis of 'designated architectures'. Time-consuming data retrieval and the manual calculation of formulas is no longer necessary.

17:30iSAS - Integration of Engineering, Initial Operation and Maintenance

Dr. Thomas Dreyer, AUCOTEC AG, Konstanz, Germany

At present, the fields of application of engineering, initial operation and maintenance in the domain of electrical engineering are dominated by a lack of information integration. In particular, for initial operation and maintenance not only this information integration missing, but ongoing experience is not captured and added to system documentation. S-TEN, an EU project, was created to support decision-makers in constantly changing technical environments and in this presentation the outline of a prototye intelligent service assist system (iSAS) will be given.

The atp International Workshops at SPS/IPC/DRIVES 2007 have been organised by Prof. Dr. B. Vogel-Heuser from the Technical University Kassel in Germany. He is also editor in chief of atp international.
