WebAssembly for the Industrial Internet-of-Things

WebAssembly for the Industrial Internet-of-Things

Sichere, skalierbare Plattformen mit Bytecode-basierten Virtuellen Maschinen
Stefan Wallentowitz, Markus Friedrich
The industrial internet-of-things is built on heterogeneous hardware/software platforms, which vary in their architecture and performance. Virtualization is an important technology for building secure and portable applications on scalable IoT deployments. Bytecode based virtual machines are coming back into focus with WebAssembly, a technology that started in the web browser and now raises interest in other use cases. In this paper we discuss a vision of scalable WebAssembly deployments in the industrial internet-of-things.

BSI Recommends: Virtual and Secure Surfing

BSI Recommends: Virtual and Secure Surfing

Clemens A. Schulz
Every day there are cyber attacks in the industrial sector − only the most spectacular incidents make the headlines. Like the attack on the automotive supplier Continental last summer or on the commercial vehicle supplier SAF-Holland in March this year. The financial damage caused by such attacks and the loss of trust among customers and employees are enormous. As protection against cyber attacks, the Federal Office for Information Security (BSI) now recommends that companies use a browser with so-called virtualised instances for the first time. This is because most attacks enter company networks via the internet. Such a browser can systematically keep attackers out of the network and is therefore a particularly effective protection.

Trends and Challenges in Factory Software

Trends and Challenges in Factory Software

Norbert Gronau ORCID Icon
Any networked information system that is used in the context of manufacturing and logistics in a factory can be referred to as factory software. This article describes six trends that will significantly influence the way software is used in factories in the near future. The trends are described in ascending order in terms of significance of impact.

Multidimensional Maturity Model for Digital Twins

Multidimensional Maturity Model for Digital Twins

Method for Systematic Classification and Assessment
Michael Lütjen ORCID Icon, Eike Broda, Jan-Frederik Uhlenkamp, Jasper Wilhelm, Michael Freitag ORCID Icon, Klaus-Dieter Thoben ORCID Icon
Digital twins are an important part of the Industry 4.0 idea. They mirror physical goods in the digital world and enhance them with additional capabilities and functions for analysis, forecasting and decisionmaking. This paper contributes to the classification and assessment of Digital Twins using a multidimensional maturity model. The presented method "DT-Assess" enables an application-specific assessment of Digital Twins. The developed maturity model consists of seven categories with a total of 31 characteristics to be evaluated. The systematic evaluation in five application scenarios allows, for the first time, a classification of the respective "digital twin" implementation or concept with the aim of identifying further development options and weaknesses.

Analysis of the Characteristics of Current Learning Factories

Analysis of the Characteristics of Current Learning Factories

Virtual reality as a possible answer to topical challenges
Christoph S. Zoller, Lars Harkemper, Wladimir Rempel
Learning factories offer the possibility to plan, execute and analyze the knowledge imparted in theory on realistic industrial systems. This article analyzes the potential of developing and operating a learning factory in a virtual environment. For this purpose, institutions with learning factories are surveyed regarding the challenges and desires in the operation of learning factories and the mentioned aspects are discussed with regard to their representability in Virtual Reality. The result shows that Virtual Reality positively influences a large part of the aspects and has a high potential to solve current challenges in the establishment and operation of learning factories.

Virtual Reality-Based Training in Industry

Virtual Reality-Based Training in Industry

Current Technical Requirements and Challenges
Benjamin Knoke, Moritz Quandt, Michael Freitag ORCID Icon, Klaus-Dieter Thoben ORCID Icon
This paper focuses on the investigation of current technical challenges in the context of industrial Virtual Reality (VR)-based training applications. This paper analyzes the current state of the art of industrial VR applications and provides a structured overview of the existing technical challenges. The identified challenges are discussed based on an industrial training scenario for the safe handling of electrical components.

The Digital Twin Theory – A New View on a Buzzword

The Digital Twin Theory - A New View on a Buzzword

Andreas Deuter, Florian Pethig
The digital twin is supposed to be a major tool for increasing productivity in the age of industrial digitalization. However, there are many heterogeneous definitions about the digital twin. This situation hardly supports the practical digital twin implementation. For this reason, the article introduces a new concept, called the Digital Twin Theory which is a theoretical framework containing several hypotheses about digital twins. The aim of the framework is a better understanding about the digital twin management in practice.

Food for thought – Introduction for Food Industry 4.0

Food for thought - Introduction for Food Industry 4.0

Severin Weiss
Implementing Industry 4.0 as the digital Agenda in all manufacturing industries and thereby increasing the competitiveness is a matter of course and clearly also applicable for the food and beverage industry. With altering customer behaviours, legal requirements as well as the increasing specialization, the industrial sectors are facing continuous challenge. Even though the automation of facilities in many cases is already put into practice, the structured integration into a holistic data concept is often missing. Through the digital networking of all processes, innovative solutions are on offer. What does Industry 4.0 mean for the food and beverage industry, where the opportunities lie and which specific implementation measures are available is subject to this article.

Control as a Service for Industrial Robots

Control as a Service for Industrial Robots

Vereinfachung von Programmierung und Inbetriebnahme durch Methoden der Virtualisierung und Augmented-Reality-Simulation
Jan Guhl, Axel Vick, Jens Lambrecht, Jörg Krüger
The methods presented allow the splitting of classic monolithic numerical controls of industrial robots and machine tools into their functional units. The core functionalities can then be brought onto different computers in even separate places. Using techniques of augmented reality allows enriching a captured scene with additional information, as a virtual model of the industrial robot or the planned paths. Combining these approaches leads to a simplified programming task for industrial robots as the programs can be visualized in their context. This decreases setup time and improves quality.

Transformation of Control Technology by Industry 4.0

Transformation of Control Technology by Industry 4.0

Einfluss von Cloud Computing und Industrie 4.0 Mechanismen auf die Steuerungstechnik für Maschinen und Anlagen
Moritz Chemnitz, Gerhard Schreck, Jörg Krüger
The third industrial revolution culminated in the Computer Integrated Manufacturing but limited computing power and the dystopia of a deserted factory prevented its success. Industry 4.0, however, stands for the integration of people, technology and organization. Based on the networking of products, tools and means of production become all relevant information available. The combination with cloud computing and big data enables the analysis and utilization of such information.
