Smart manufacturing is strongly correlated with the digitization of all manufacturing activities. This increases the amount of data available to drive productivity and profit through data-driven decision making programs. The goal of this article is to assist data engineers in designing big data analysis pipelines for manufacturing process data. Thus, this paper characterizes the requirements for process...
Hardware-in-the-Loop (HIL) is a well-established concept for developing and testing embedded systems. While it is widely used in industrial automation and the automotive area, it is rarely applied to Building Automation Systems (BAS). This work proposes the interconnection of a prominent building automation protocol, namely Building Automation and Control network (BACnet), and a simulator, PowerDEVS,...
Building planning as well as automation systems engineering involve numerous disciplines participating in a many-phase process. However, the information transitions between these different phases are mostly carried out manually which results in multiple sources of errors. Additionally, information which is already present is repeatedly manually re-entered during the whole workflow. This especially...
Most of today's security solutions, such as security information and event management (SIEM) and signature based IDS, require the operator to evaluate potential attack vectors and update detection signatures and rules in a timely manner. However, today's sophisticated and tailored advanced persistent threats (APT), malware, ransomware and rootkits, can be so complex and diverse, and often use zero...

Current trends and advancements in the Internet of Things and the Semantic Web have already found their way into the domain of building automation. As machine-to-machine communication and integration of heterogeneous building automation technologies are of increasing importance, interoperability is a necessary precondition. In order to support building automation communication, a customized set of...
KNX is a worldwide open standard for home and building automation, which originated from a classical fieldbus protocol. While the needs for interacting with the upcoming Internet of Things (IoT) were already partially addressed by the recent KNX Web Services application note, KNX IP networking still supports IPv4 only. This paper proposes the usage of IPv6 networking as native KNX medium. The most...
Over the previous years, many service-oriented (SO) solutions have been proposed by European research projects for the technological advancement of industrial systems. These projects typically include a software reference architecture (RA) based on the concepts of service-oriented architectures (SOA) and, often-times, an accompanying technology stack to guarantee system-wide interoperability. In this...
In the life cycle of buildings, plenty of different disciplines and companies are involved. Therefore, a unified information base for the whole building and its components and technical equipment is highly beneficial. One approach aiming at this goal is Building Information Modelling (BIM). There exist standards mostly focusing on architectural and building physical properties, like the Green Building...
Integrating formally separated control systems of a city by means of Information and Communication Technology (ICT) is well known under the term “Smart City”. The benefit is a more energy and cost efficient city. In the domain of road traffic an open traffic data platform shall be the base for smart road traffic infrastructure and services. The idea is to pool available data from road side sensors...
In order to handle the increasing complexity of smart grid systems, detailed use case and requirements engineering has become indispensable. For this purpose the Smart Grid Reference Architecture Model (SGAM) has emerged as the major methodology. This paper presents a textual Domain Specific Language (DSL) based on SGAM, optimized for rapid prototyping of smart grid applications using a model-driven...
The automated tracking and analysis of sport activities has become increasingly important in the recent years. While it is already very common in endurance sports, in weight training the tracking is still done mainly manually, which is a tedious task. This work aims at exploring the problem of automated tracking and analysing of weight training exercises by the use of low-power smart fitness devices...
Today's buildings provide continuously growing amounts of data monitored from diverse sensors. With regard to the similarly increasing energy needs of buildings, accurate evaluation and analysis of these data can be used in order to improve energy efficiency and reduce overall energy consumption of buildings. Hence, this work introduces a comprehensive framework based on well-known data analytics...
Research efforts for the Industrial Internet of Things (IIoT) have placed great emphasis on the use of vertical integration as a mainline strategy for the realisation of the fourth industrial revolution (Industrie 4.0). The present paper proposes the use of a distributed Gateway Service Bus (GSB) as a plant-wide and resilient platform for vertical integration, field level reconfiguration, and distributed...
Within the framework of the German reactor safety research, generic experimental investigations were carried out aiming at thermal-hydraulic consequences of physicochemical mechanisms, caused by dissolution of zinc in boric acid during corrosion processes at hot-dip galvanized surfaces of containment internals at lower coolant temperatures and the subsequent precipitation of solid zinc borates in...
In building automation systems, the diversity of existing field level networks is a major challenge for fully integrated solutions. Typical approaches achieve integration by shifting the needed complexity to the automation or management layer. In contrast, this paper focuses on leaving the complexity at the field level to provide a homogeneous view to upper layers without compromising reliability...
With the increasing popularity of the Internet, Ethernet and IP networks are commonly used as backbone technologies in the domain of building automation. For the area of networked fire alarm systems, however, dependability aspects need to be met and reliable communication must be guaranteed to satisfy functional and normative constraints. Due to the economic pressure in this domain, it is desirable...
Building automation is an important part of state-of-the-art building management in order to attain most efficient operation in accordance with comfort requirements, energy consumption, or budget allowance. For this purpose, current building management systems enable communication with subjacent systems at the field and automation level by definition of mostly syntactical technology mappings. However,...
With the ever-increasing emphasis on the importance of vertical integration for the fourth industrial revolution (Industrie 4.0), we contend that the largest potential lies in the replacement of single-purpose gateway-ing solutions with distributed gateway service bus (GSB) technologies. Within this paper, we primarily focus on the aspect of routing between variously grouped GSB components. We base...
This paper introduces a concept for bringing dependability into the area of building automation. The proposed approach is able to extend existing building automation networks with dependability features. For this purpose, the communication stack of a particular system is extended by adding an intermediate layer. This so-called dependability layer is transparent to allow seamless integration. Thereby,...
