Die Industrie ist im Wandel. Die Grenzen zwischen Industrien, Anwendungsbereichen und Unternehmen verschwinden immer weiter, sind teils kaum noch in ihrer alten Ausprägung zu erkennen. Auch die industrielle Automation kann und sollte sich diesem Trend nicht entziehen. Immer mehr Technologien und Paradigmen anderer Bereiche gewinnen an Bedeutung. Hinzu kommt, dass die Anzahl und die Vielfalt an Geräten, Anwendungen, Anforderungen und Technologien stetig wächst. Diese Arbeit befasst sich mit Ansätzen, die es ermöglichen, einigen Aspekten der wachsenden Komplexität zu begegnen. Dabei handelt es sich um Technologien und Konzepte zum Thema Management, genauer zum Netzwerk-, System- und Dienste-Management. Ziel ist es nicht nur einen Ansatz zu finden, der gegenwärtigen Ansprüchen genügt, sondern auch noch für kommende Entwicklungen geeignet ist.

Economic utilization of geothermal networks under agricultural surfaces needs large agricultural areas. In order to exploit the cultivated land more effectively, this paper proposes a novel locally vibrating plough system that employs a hydraulic actuator direct on the plough blade instead of the state of the art external vibration units. Starting with a description of geothermal networks under agricultural surfaces and the construction technology in details, the contribution shows different concepts, the development and test of the most promising solution for imprinting local vibrations at the cutting edge with the goal of traction force reduction. A virtual demonstrator, the test rig set-up and the control concepts are described. Both of the closed-loop simulation and experimental position control of the entire vibration system demonstrate that the novel design has impressive performance improvement. Finally, the integration of the vibration system into a prototype tool is shown and the reduction of the traction force is proven by experiments carried out with a tractor on a testing field.

The effects of metastable tetragonal zirconia on the properties of Ordinary Portland Cement were observed during which the effect of crystallite size pH on the preparation solution, precursor salt, and the presence of co-precipitates, Fe(OH)3, SnO2 and SiO2 on the crystallization temperature, enthalpy and crystal structure, immediately following the crystallization exothermic burst phenomenon in ZrO2 were measured. Thermal analysis and x-ray methods were used to determine crystallite sizes and structures immediately following the exothermic burst. Comparisons were made for zirconias prepared from oxychloride, chloride and nitrate solutions. The existence of tetrameric hydroxidecontaining ions in oxychloride precursor is used to rationalise low values of crystallization enthalpy. The position of the crystallization temperature, Tmax was not dependent on crystallite size alone but also on the pH at which the gel was made, the surface pH after washing, and the presence of diluent oxides. Enthalpy v r1/2 and Tmax v (diluent vol)1/3 relationships indicate that surface coverage effects dominate a surface nucleated phenomenon. The data established for ZrO2 systems was used to develop tetragonal-ZrO2-SnO2 powders capable of improving the mechanical properties of Ordinary Portland Cement discs. The ZrO2-OPC discs were prepared by powder mixing, water hydration and uniaxial pressing. Vicat needle tests showed that tetragonal-ZrO2 increases the initial setting rate. Microscopy indicated that porosity distribution changes near to ZrO2 particles. Zirconia has also been introduced into OPC discs by vacuum infiltration methods developed for solutions and colloidal suspensions. Comparisons between OPC discs and the OPCtetragonal ZrO2 composites have been made on the basis of diametral compression strength, Young’s modulus, hardness and toughness (K1c), as estimated by the cracked indentation method. Bell-shaped curves are found for the way the mechanical properties are changed as a function of Zirconia content.

Ο στόχος της παρούσας διπλωματικής εργασίας είναι ο έλεγχος και αποκατάσταση της θερμοκρασίας και της υγρασίας από απόσταση σε ένα χώρο ο οποίος απαιτεί συγκεκριμένες τιμές των δύο παραπάνω μεγεθών. Ένας τέτοιος χώρος μπορεί να είναι μια αίθουσα χειρουργείου ή μια μονάδα εντατικής θεραπείας. Ανάλογα με τις επιθυμητές θερμοκρασίες που έχουν τεθεί, ενεργοποιούνται οι βάνες του θερμαντικού ή του ψυκτικού στοιχείου. Όταν η υγρασία του χώρου είναι κατώτερη της επιθυμητής, ενεργοποιείται η τρίοδος βάνα ατμού. Όταν η υγρασία του χώρου είναι υψηλότερη της επιθυμητής ενεργοποιείται η τρίοδος βάνα του ψυκτικού στοιχείου για επιπλέον ψύξη (αφύγρανση) και παράλληλα, αν χρειαστεί ενεργοποιεί και την τρίοδο βάνα του θερμαντικού στοιχείου για να διατηρήσει τη θερμοκρασία του χώρου στα επιθυμητά επίπεδα. Όλα αυτά υλοποιούνται με τη βοήθεια του PLC S7 300 όσο αφορά το λειτουργικό μέρος, της μονάδας CP 343-1 Lean για την επικοινωνία της εγκατάστασης από απόσταση μέσω ethernet, το LabVIEW 9.0 για την υλοποίηση του SCADA(Supervisory Control and Data Acquisition) και τέλος ο OPC SERVER της National instrument για την επικοινωνία του PLC S7 300 με το LabVIEW 9.0. / The scope of this thesis is the control and restoration of temperature and humidity from distance in environments which demand precise values of these two measurements. Such an environment can be an Operating Room or an Intensive Care Unit. The valves of the heating or the cooling element are activated according to the desired temperature. When room humidity is below the desired one, the dew three-port valve is activated. On the other hand when humidity is above the desired level the three-port valve of the cooling element is activated for further cooling (dehydration) and at the same time, if needed, it activates the three-port valve of the heating element to maintain the room temperature at the desired level. This is possible with the use of PLC S7 300, when it comes to the functional part, the CP 343-1 Lean unit for the distant communication of the installation through the use of Ethernet, the LabVIEW 9.0 for the implementation of the SCADA(Supervisory Control and Data Acquisition) and the OPC SERVER of the National Instrument for the communication of the PLC S7 300 with LabVIEW 9.0.

This thesis details the design of a protocol translator between the industrial-automation protocol OPC UA, and HTTP. The design is based on the architecture of the protocol translator of the Arrowhead framework, and is interoperable with all of its associated protocols. The design requirements are defined to comply with a service-oriented architecture (SOA) and RESTful interaction through HTTP, with minimal requirement of the consuming client to be familiar with OPC UA semantics. Effort is put into making translation as transparent as possible, but limits the scope of this work to exclude a complete semantic translation. The solution presented in this thesis satisfies structural- and foundational interoperability, and bridges interaction to be independent of OPC UA services. The resulting translator is capable of accessing the content of any OPC UA server with simple HTTP-requests, where addressing is oriented around OPC UA nodes.

Internet of Things (‘IoT’) systems are complex, asynchronous solutions often comprised of various software and hardware components developed in isolation of each other. These components function with different degrees of reliability and performance over an inherently unreliable network, the Internet. Many IoT systems are developed within silos that do not provide the ability to communicate or be interoperable with other systems and platforms. Literature exists on how these systems should be designed, how they should interoperate, and how they could be improved, but practice does not always consult literature. The work brings together a proposed reference architecture for the IoT and engineering practices for flow semantics found in existing literature with a commercial implementation of an IoT platform. It demonstrates that the proposed IoT reference architecture and flow-service-quality engineering practices when integrated together can produce a more robust system with increased functionality and interoperability. It shows how such practices can be implemented into a commercial solution, and explores the value provided to the system when implemented. This work contributes to the current understanding of how complex IoT systems can be developed to be more reliable and interoperable using reference architectures and flow semantics. The work highlights the value of integration of academic solutions with commercial implementations of complex systems.

In order to test an automation code for a production cell it is necessary to have access to the physical model. Therefore, the automation code is validated in the end of the design process. Finding and correcting faults in the code takes time and changes late in the design process tend to be expensive. Having a virtual model of a production cell with the same features as a physical model enables to test automation code and evaluate different features in an early stage of development. The process of having a virtual model to validate code and try out new features is called Virtual Commissioning (VC). The ability to detect errors in the code and identify problems early in the process can lower the lead time for the project and reduce the overall cost. Virtual Commissioning is a relative new process step in the industry and have so far mainly used in larger enterprises. This project has been done at a company named NPB Automation AB, located in Jönköping, Sweden. NPB is a smaller company that designs and produces robot cells that are fully automated. This project is an investigate to see if a software that can perform a Virtual Commissioning should be added to their lineup of tools. This task has been managed by empirically finding how a Virtual Commissioning can be set up. To find out how Virtual Commissioning can affect different fields at the company interviews were held with personnel from different working fields. To get practical knowledge and verifying that Virtual Commissioning can be performed on a robot cell produced at the company, a Virtual Commissioning were set up of a subsystem of a robot cell. The Virtual Commissioning in this project was set up with the software Emulate3D connected to a Rockwell PLC model 1769- L33ERMS, the PLC code used were written in Studio 5000 Logix Designer. The conclusion of his project is that Virtual Commissioning can reduce time to market by reducing the commissioning time. The tasks where Virtual Commissioning will benefit the most is in new projects or when validating changes.

This award solves design of two models that are designed to teach on PLC and in the future on the Control Web. Both models should be used in LabLink system, which allows you to remotely working on laboratory tasks. The first software model simulates the movement of trains on rail in relation on control from the PLC. The second model is a physical model of drill. In both models are solid managing and type of construction, which allows operation without physical intervention.
