Industrie 4.0 introduces a concept of digitalized production by allowing agile and flexible integration of new business models while maintaining manufacturing costs and efficiency at the reasonable level. In addition, cloud computing is one of the IT trends that is used nowadays to offer services on demand from a virtual environment in enterprise and office areas. The use of cloud computing in an...
Multipath (MP) communication is widely used to improve the reliability of communication networks in different domains. With this regard, we have also proposed MP communication to improve communication reliability for cyber-physical systems (CPSs) when using the Internet [1]. More specifically, we proposed using different end-to-end (e2e) paths that use different pairs of Internet service providers...
Nowadays, industrial networks are characterized by complex architectures of hybrid, wired and wireless segments, combining automation and information technology (IT). Their operation is supported by network management facilities. Network monitoring is a basis for management as it provides the necessary status information. This paper presents an approach to apply a monitoring concept coming from the...
Currently, cloud computing offers flexible, dynamic and cost effective computing outsourcing, but it limits these economic and operational benefits to non real-time and non safety-critical systems. This is because of the lack of alternative control, supported by current cloud infrastructures, in case of a broken cloud link. While steps have been taken in using cloud infrastructures for soft real-time...
It is our pleasure to welcome all participants to the 21st IEEE International Conference on Emerging Technologies and Factory Automation held in Berlin, in Germany.
The exhaustive digitalization of the economy, and to be more specific, of industrial production systems results in a new quality of information transparency. This is the basis for added values in terms of effectiveness, quality, and individuality. However, these added values also result in an increased exposure to Cyber-Security threats, due to the increased digitalization, information transparency...
Recent developments under the term Smart Grid change how users consume electricity and interact with the power grid. Smart metering and energy management are developments that transform the yet passive energy consumer to a participant that is actively involved in the energy market by using variable energy tariffs or by demand-response services. But such functionality demands a platform that integrates...
For cyber-physical systems (CPSs), communications system reliability is an indispensable requirement to realize them in critical infrastructures. One of the important attributes of system reliability is availability. System availability is broadly defined as the proportion of time that the system will provide service. In some CPSs, such as smart grids, the units are distributed over large geographical...
Scheduling of time triggered communication systems belongs to the well known hard mathematical optimization problems. This paper tackles the communication scheduling problem in redundant network topologies, where the real-time process data has to be duplicated and sent on two different paths to its destination. This paper proposes an algorithm that is able to find a feasible schedule in a short time,...
Software-Defined Networking (SDN) is a promising approach to build future industrial networks. The disruptive change of network architecture and management opens new possibilities in various application domains. While the approach is already deployed in several domains and was also initially examined to be used in the industrial area, many open questions arise when assessing the risks and improvements...
Durch die zunehmende Dezentralisierung von Sensoren, Aktoren und Verarbeitungseinheiten sind Rechnernetze erforderlich, die bestimmte Reaktionszeiten einhalten müssen. Sie stellen somit eine wichtige Infrastruktur in der Systemarchitektur von Echtzeitsystemen dar.
Cyber-Physical Systems (CPSs) represent a new paradigm of future intelligent systems. They consist of loosely coupled subsystems which interact with mechanisms of Service-oriented Architecture (SoA). In this paper we try to open a new topic in industrial communications. This topic is focused on basic communication patterns within CPSs. Patterns are abstract and generic solutions for common problems...
The term Industrie 4.0 carries the vision of smart factories, which automatically adapt to changes and assist the human as much as possible during operation and maintenance. This includes smart human machine interfaces, which reduce the chances of errors and help to make the right decisions. This paper presents an approach to equip the maintenance software running on a tablet PC with augmented reality...
In the industrial automation a paradigm shift from centralized, static automation structures to reconfigurable manufacturing systems (RMS) might be lie ahead. RMS are seen as a key enabler for the required changeability of future production companies since they can reduce the engineering effort needed for the reconfiguration of existing or the construction of new production systems. However, it is...
In this paper, an FPGA based FIFO with efficient memory management is proposed, which allows fast forwarding of real-time Ethernet frames. There are two main drawbacks of the existing FIFO implementations with respect to the buffering of Ethernet frames. Currentness of data is not guaranteed in case of buffer overflow because the new frames are dropped in this case. Furthermore, exhaustive resources...
Cyber-physical systems (CPSs) are a new paradigm of control systems where control, communication, and computation fields intersect. Applications of such systems are expected to play an important role in many domains in the future. This includes critical domains such as transportation and health domains. Hence, it is quite important for such systems to operate reliably. Moreover, many CPS applications...
Cyber-physical systems (CPSs) represent a new generation of control systems where distributed local control systems are connected not only physically, but also computationally by means of communication networks. CPSs target introducing intelligence beside traditional monitoring and control functionalities in a way that optimize the performance of the overall system. However, the realization of many...
Future market conditions require production systems which can be easily adapted to changing demands. However, the engineering process of industrial automation systems is characterized by high manual configuration efforts. Thus, the reconfiguration of such system leads to time-intensive and expensive downtimes. Therefore, this paper will present a concept on reducing the engineering effort — at least...
According to the vision of the Internet of Things the seamless and flexible networking of everyday objects will become an important field of application for Internet-based communication. The simple integration of these devices into a communication system often requires wireless technologies, especially when there is no wired infrastructure available. Cellular networks of the third and fourth generation...
