Die Entwicklung von Feldgeräten ist ein äußerst komplexer Vorgang, welcher auf vielen Vorrausetzungen aufsetzt, diverse Anforderungen und Randbedingungen mitbringt und bisher wenig beachtet und veröffentlicht wurde. Angesichts der fortschreitenden Digitalisierung drängen immer mehr Anbieter auf den Automatisierungsmarkt. So sind aktuell zunehmend Technologien und Ansätze aus dem Umfeld des Internet of Things im Automatisierungsbereich zu finden. Diese Ansätze reichen von Sensoren ohne die in der Industrie üblichen Beschreibungen bis hin zu Marktplätzen, auf denen Integratoren und Anwender Softwareteile für Anlagen kaufen können. Für die neuen Anbieter, die häufig nicht aus dem klassischen Automatisierungsgeschäft kommen, sind die bisher bestehenden Modelle, Funktionalitäten, Profile und Beschreibungsmittel nicht immer leicht zu verwenden. So entstehen disruptive Lösungen auf Basis neu definierter Spezifikationen und Modelle. Trotz dieser Disruptivität sollte es das Ziel sein, die bewährten Automatisierungsfunktionen nicht neu zu erfinden, sondern diese effektiv und effizient in Abhängigkeit der Anforderungen auf unterschiedlichen Plattformen zu verwenden. Dies schließt ihre flexible Verteilung auf heterogene vernetzte Ressourcen explizit ein. Dabei können die Plattformen sowohl klassische Feldgeräte und Steuerungen sein, als auch normale Desktop-PCs und IoT-Knoten. Ziel dieser Arbeit ist es, eine Werkzeugkette für den modellbasierten Entwurf von Feldgeräteapplikationen auf Basis von Profilen und damit für den erweiterten Entwurf von verteilten Anlagenapplikationen zu entwickeln. Dabei müssen die verschiedenen Beschreibungsmöglichkeiten evaluiert werden, um diese mit detaillierten Parameter- und Prozessdatenbeschreibungen zu erweitern. Außerdem sollen modulare Konzepte genutzt und Vorbereitungen für die Verwendung von Semantik im Entwurfsprozess getroffen werden. In Bezug auf den Geräteengineeringprozess soll der Anteil des automatisierten Geräteengineerings erweitert werden. Dies soll zu einer Flexibilisierung der Geräteentwicklung führen, in der die Verschaltung der funktionalen Elemente beim Endkunden erfolgt. Auch das Deployment von eigenen funktionalen Elementen auf die Geräte der Hersteller soll durch den Endkunden möglich werden. Dabei wird auch eine automatisierte Erstellung von Gerätebeschreibungen benötigt. Alle diese Erweiterungen ermöglichen dann den letzten großen Schritt zu einer verteilten Applikation über heterogene Infrastrukturen. Dabei sind die funktionalen Elemente nicht nur durch die Gerätehersteller verteilbar, sondern diese können auch auf verschiedenen Plattformen unterschiedlicher Gerätehersteller verwendet werden. Damit einher geht die für aktuelle Entwicklungen wie Industrie 4.0 benötigte geräteunabhängige Definition von Funktionalität. Alle im Engineering entstandenen Informationen können dabei auf den unterschiedlichen Ebenen der Automatisierungspyramide und während des Lebenszyklus weiterverwendet werden. Eine Integration diverser Gerätefamilien außerhalb der Automatisierungstechnik wie z. B. IoT-Geräte und IT-Geräte ist damit vorstellbar. Nach einer Analyse der relevanten Techniken, Technologien, Konzepte, Methoden und Spezifikationen wurde eine Werkzeugkette für den modellgestützten Entwurf von Feldgeräten entwickelt und die benötigten Werkzeugteile und Erweiterungen an bestehenden Beschreibungen diskutiert. Dies Konzept wurde dann auf den verteilten Entwurf auf heterogener Hardware und heterogenen Plattformen erweitert, bevor beide Konzepte prototypisch umgesetzt und evaluiert wurden. Die Evaluation erfolgt an einem zweigeteilten Szenario aus der Sicht eines Geräteherstellers und eines Integrators. Die entwickelte Lösung integriert Ansätze aus dem Kontext von Industrie 4.0 und IoT. Sie trägt zu einer vereinfachten und effizienteren Automatisierung des Engineerings bei. Dabei können Profile als Baukasten für die Funktionalität der Feldgeräte und Anlagenapplikationen verwendet werden. Bestehende Beschränkungen im Engineering werden somit abgeschwächt, so dass eine Verteilung der Funktionalität auf heterogene Hardware und heterogene Plattformen möglich wird und damit zur Flexibilisierung der Automatisierungssysteme beiträgt. / The development of field devices is a very complex procedure. Many preconditions need to be met. Various requirements and constrains need to be addressed. Beside this, there are only a few publications on this topic. Due to the ongoing digitalization, more and more solution providers are entering the market of the industrial automation. Technologies and approaches from the context of the Internet of Things are being used more and more in the automation domain. These approaches range from sensors without the typical descriptions from industry up to marketplaces where integrators and users can buy software components for plants. For new suppliers, who often do not come from the classical automation business, the already existing models, functionalities, profiles, and descriptions are not always easy to use. This results in disruptive solutions based on newly defined specifications and models. Despite this disruptiveness, the aim should be to prevent reinventing the proven automation functions, and to use them effectively, and efficiently on different platforms depending on the requirements. This explicitly includes the flexible distribution of the automation functions to heterogeneous networked resources. The platforms can be classical field devices and controllers, as well as normal desktop PCs and IoT nodes. The aim of this thesis is to develop a toolchain for the model-based design of field device applications based on profiles, and thus also suitable for the extended design of distributed plant applications. Therefore, different description methods are evaluated in order to enrich them with detailed descriptions of parameters and process data. Furthermore, c oncepts of modularity will also be used and preparations will be made for the use of semantics in the design process. With regard to the device engineering process, the share of automated device engineering will be increased. This leads to a flexibilisation of the device development, allowing the customer to perform the networking of the functional elements by himself. The customer should also be able to deploy his own functional elements to the manufacturers' devices. This requires an automated creation of device descriptions. Finally, all these extensions will enable a major step towards using a distributed application over heterogeneous infrastructures. Thus, the functional elements can not only be distributed by equipment manufacturers, but also be distributed on different platforms of different equipment manufacturers. This is accompanied by the device-independent definition of functionality required for current developments such as Industry 4.0. All information created during engineering can be used at different levels of the automation pyramid and throughout the life cycle. An integration of various device families from outside of Automation Technology, such as IoT devices and IT devices, is thus conceivable. After an analysis of the relevant techniques, technologies, concepts, methods, and specifications a toolchain for the model-based design of field devices was developed and the required tool parts, and extensions to existing descriptions were discussed. This concept was then extended to the distributed design on heterogeneous hardware and heterogeneous platforms. Finally, both concepts were prototypically implemented and evaluated. The evaluation is based on a two-part scenario from both the perspective of a device manufacturer, and the one of an integrator. The developed solution integrates approaches from the context of Industry 4.0 and IoT. It contributes to a simplified, and more efficient automation of engineering. Within this context, profiles can be used as building blocks for the functionality of field devices, and plant applications. Existing limitations in engineering are thus reduced, so that a distribution of functionality across heterogeneous hardware and heterogeneous platforms becomes possible and contributing to the flexibility of automation systems.

This thesis proposes a novel approach to power electronics system design that is based on the open-architecture distributed digital controller and modular power electronics building blocks (PEBBs). The proposed distributed digital controller partitions the controller in three levels of control authority. The power stage controller, designated as hardware manager, is responsible for low-level hardware oriented tasks; the high level controller, designated as applications manager, performs higher-level application-oriented tasks; and the system level controller handles system control and monitoring functions. Communications between the hardware-oriented controller and the higher-level controller are implemented with the previously proposed 125 Mbits/sec daisy-chained fiber optic communication protocol. Real-time control and status data are communicated by means of communication protocol. The distributed controller on the power converter level makes the system open, flexible and simple to use. Furthermore, this work gives an overview and comparison of current state-of-the-art communication protocols for real-time control applications with emphasis on industrial automation and motion control. All of the studied protocols have been considered as local area networks (LAN) for system-level control in power converter systems. The most promising solution has been chosen for the system level communication protocol. This thesis also provides the details of design and implementation of the distributed controller. The design of both the hardware and software components are explained. A 100 kVA three-phase voltage source inverter (VSI) prototype was built and tested using the distributed controller approach to demonstrate the feasibility of the proposed concept. / Master of Science

Electro Hydrostatic Actuators (EHA) are emerging as a viable option for industrial machine builders as the design combines the best of both electro-mechanical and electro-hydraulic technologies. The EHA is a highly integrated, compact alternative to traditional hydraulic solutions. Automation engineers moving toward electro-mechanical actuation in pursuit of energy efficiency and environmental cleanliness, will find an EHA an attractive option for high force density actuators. This paper will address the factors to consider when assessing an industrial machine’s application suitability for this latest innovation in actuation. It describes principal base circuits, a concept for EHA building blocks and a realized pilot application as well as challenges on actuator and components level.

A tecnologia emergente dos dispositivos móveis como telefones celulares, handhelds e smartphones trouxe um novo paradigma para o uso desses equipamentos, que, além das convencionais chamadas de áudio, hoje suportam vídeo, internet e redes sem fio. Várias aplicações têm sido desenvolvidas para esse ambiente. Por outro lado, na área da automação industrial, os instrumentos de campo modernos contêm embutidos, internamente, conjuntos de informações que proporcionam grande oportunidade para a gestão de ativos. A necessidade do gerenciamento de ativos ocorre na fase de operação da planta industrial e é realizada por meio de ajustes finos, calibrações, alteração de configurações e manutenções, com o objetivo de se evitar paradas indesejadas. Esse trabalho insere-se no contexto de interface entre esses dois mundos: a computação móvel e o gerenciamento de ativos. Nesse sentido, é desenvolvida uma análise dos padrões abertos PROFIBUS PA, HART e Foundation Fieldbus e o uso das suas características aplicado ao gerenciamento de ativos. É apresentada, ainda, uma proposta e verificação de viabilidade técnica de uma arquitetura aplicada ao gerenciamento de ativos a partir de um dispositivo móvel usando-se um canal de comunicação seguro baseado no padrão CyberOPC para acesso à planta industrial / The emerging technology of mobile devices like cell phones, hand helds and smartphones has brought a new paradigm for the use of such equipment, witch, in addition to conventional audio calls, now supports video, internet and wireless networks. Several applications have been developed for this environment.
