För att korta ner den totala driftsättningstiden i projekt beslutade Volvo Cars Skövde om att undersöka möjligheterna för verifiering av PLC-logik mot simuleringsprogram. Det övergripande målet med examensarbetet var att undersöka möjligheterna för att upprätta kommunikation mellan flödesimuleringsprogrammet Siemens Plant Simulation och en PLC-enhet. En ingripande förståelse av området virtuell driftsättning skapades vid skrivandet av referensramen och en litteraturstudie vilket legat till grund för det fortsatta praktiska arbetet. Genom en datainsamling med intervjuer, diskussioner och en omfattande litteraturstudie kunde en bättre förståelse bildas kring hur kommunikation mellan de olika programmen fungerar, samt viktiga punkter som bör has i åtanke vid virtuell driftsättning överlag. Ett hypotetiskt system utvecklades i Plant Simulation av Volvo Cars Skövde för att användas som testsystem. I emuleringsmjukvaran Simumatik3D skapades en modell för att efterlikna Plant Simulation modellen samtidigt som PLC-logiken utvecklades i Siemens Step 7. Under utvecklingens gång verifierades delsystem i Simumatik3D mot den skapade PLC-logiken tills det att modellen var färdigutvecklad. För att säkerhetsställa att både Simumatik3D modellen och Plant Simulation modellen var valid undersöktes ett antal valideringspunkter. Experimentfasen tog vid efter valideringstestet där olika scenarier undersöktes och testades för att föra upp eventuella problem i modellerna till ytan. En omfattande utvärdering presenteras där hela uppbyggnadsfasen av modeller utvärderas med avseende på tidsåtgång, för- och nackdelar och kommunikation med PLC. De två programmen Simumatik3D och Plant Simulation utvärderades mot varandra för att få ut vilket program som mest lämpar sig för virtuell verifiering av PLC-logik. Ett översiktligt arbetssätt togs fram utifrån den utvärdering som gjorts samt erfarenheter från genomförandet av arbetet. Resultatet av det framtagna arbetssättet presenteras vilket beskriver uppdelningen mellan beställare och leverantör, kommunikationen mellan parterna samt en överskådlig visualisering av arbetssättets process. Resultatet från utvärderingen visade att Simumatik3D lämpar sig åt att verifiera PLC logik på detaljnivå. Utvärderingen visade även att PLC-logik kan verifieras med hjälp av Plant Simulation, dock inte på samma detaljnivå. Plant Simulation lämpar sig istället till att göra simuleringsmodeller mer verklighetstrogna. Virtuell driftsättning av PLC-logik är ett nytt koncept på Volvo Cars Skövde och därför kan resultatet från detta arbete ligga till grund för fortsatt arbete inom detta område. Virtuell verifiering av PLC-logik diskuteras där flera aspekter som är viktiga att tänka på presenteras. Projektens huvudmål att virtuellt verifiera PLC-logik mot simuleringsprogram uppnåddes och gav goda resultat, de uppsatta delmålen resulterade i en omfattande utvärdering och framtida rekommendationer.To shorten project lead times Volvo Cars Skövde decided to explore the possibilities regarding verifi-cation of PLC-logic in simulation programs. The overall objective of the thesis was to analyze the pos-sibilities for establishing communication between the flow simulation program Plant Simulation and a PLC-device. A thorough understanding of the area virtual commissioning was obtained by writing the frame of reference and a literature review which served as basis for the continued practical work. Through a collection of interviews, discussions and an extensive literature review a better under-standing regarding how the communication between the different programs works, along with im-portant points that should be considered under a virtual commissioning project was obtained. A hy-pothetical system was developed in Plant Simulation by Volvo Cars Skövde to be used as a test sys-tem. The Simumatik3D model was created by emulating the Plant Simulation model and at the same time developing the PLC-logic in Siemens Step 7. During the development progress subsystems were verified in Simumatik3D against the created PLC-logic until the model was fully developed. To make sure that both the Simumatik3D model and the Plant Simulation model was valid a number of valida-tion points were tested. After the validation test the experimental phase started were different sce-narios were analyzed and tested to bring up any problems in the models to the surface. A thorough evaluation is presented in which the entire construction phase of the models is evaluated in terms of time required, advantages and disadvantages and communication with the PLC-device. The two pro-grams Simumatik3D and Plant Simulation was evaluated against one another in order to find out which program that is the most suited for virtual verification of PLC-logic. An overall methodology was developed based on the evaluation carried out and the experience gained from the implementa-tion of the work. The result from the developed methodology is presented which describes the parti-tion between the client and supplier, the communication between them and a visualization of the methodology-process. The result from the evaluation showed that Simumatik3D was more suitable for verification of PLC logic on a detailed level. The evaluation also showed that the PLC logic could be verified with Plant Simulation, but not on the same detailed level. Plant Simulation was more suit-able for making simulation models more realistic. Virtual commissioning of PLC-logic is a new con-cept on Volvo Cars Skövde and therefore can the result from this thesis form a basis for future work in this area. Virtual verification of PLC-logic is discussed in which several important aspects to think about is presented. The projects main goal to virtually verify PLC-logic in simulation programs was achieved and yielded good results, the partial objectives resulted in a thorough evaluation and future recommendations.

PLC kan idag vara det mest använda styrsystemet till industriella applikationer. Verifikation av programmerad PLC-logik är av stort värde och kan göras på olika sätt. ÅF Karlstad vill idag börja se över möjligheter till implementering av Virtual Commissioning som ett alternativ till minskning av ledtider. I det stora hela blev målet för detta projektarbete att i Xcelgo Experior bygga upp en 3D-miljö som liknar en saltvatten-process på Barilla i Filipstad, skriva PLC-logiken i Siemens TIA-portalen och testköra logiken i 3D-miljön. Och av detta kunna ge underlag till eventuella investeringar i denna teknik för ÅF Karlstad. Gränssnittet Xcelgo Experior visade sig var funktionellt och lättarbetat. Dock hann inte programutvecklarna få i stånd den uppdatering av modulkatologen som krävts för att tillräckligt kunna efterlikna Barillas process att det försvarbart skulle kunna verifiera PLC-logiken. Efter överläggande med min handledare på ÅF, Anders Emanuelsson, bestämdes att i stället verifiera logiken visuellt i Siemens HMI. Då detta projektarbete endast delvis kommer uppfylla de syften och mål som satts kommer istället en verifiering av PLC-logiken för processen att utgöras av Siemens HMI. Dock har användandet och testkörning av mindre skriven kod, anpassat för nuvarande version av Xcelgo, givit en bild av möjligheterna att effektivt validera PLC-logik då en version lämpad mer för den Värmländska industrin kommit.

The theme and goal of this diploma is a draft and a method of application of a drive algorithm of an omni directional robot. The robot is driven with the aid of a PCL from the X20 series, produced by Bernecker&Rainer. The propulsion is provided using 3 integrated regulating driving mechanisms, IclA D065 produced by SIG Positec, which communicate via the CAN bus. Furthermore, the robot uses sensors to read the positioning of its chassis and undercarriage in order to identify the traction quality of the surface of the terrain below and subsequently reduce skidding. This sensor uses the RS 232 bus to communicate with the PLC. Thanks to all the above-mentioned and characteristics of power supply, the result achieved is a totally autonomous machine.

Detta arbete var beställt av Sjöfartshögskolan i Kalmar. Skolan ville ha en enhet som kunde mäta aktiv-, reaktiv- och skenbar effekt, ström, spänning, frekvens och cosϕ på en generator och som kommunicerade vidare dessa värden till en PLC. Detta för att kunna lastfördela lasten mellan ett antal generatorer i kursen Tillämpad elteknik 15 hp där studenterna bygger en generatorinstallation med tre generatorer. Ett funktionsblock för lastfördelning skulle också programmeras. Prototypen som konstruerades baserades på en Arduino Ethernet och kommunikationen löstes med Modbus TCP/IP över Ethernet. Ett lastfördelningsprogram programmerades i form av ett funktionsblock som studenterna kunde importera till CoDeSys v2.3 och använda i sina installationer. Prototypen kunde läsa av värdena med ungefär samma noggrannhet som ett kommersiellt instrument som använder sig av samma mätteknik som prototypen. Uppdateringsfrekvensen var dock lägre än hos ett kommersiellt instrument. Kommunikationen med PLC:n fungerade utan problem. Då ingen undervisning hölls i arbetets slutskede kunde inte lastfördelningen testas på en fullskalig anläggning. Lastfördelningsprogrammet klarade dock av att hålla rätt frekvens på en ensam generator och fungerade som tänkt när programmet testades i en simulator. Prototypen gav fel mätvärden vid kapacitiv last. Vid jämförelse med en kommersiell tångamperemeter visade sig mätfelet bero på mätmetoden då båda gav liknande resultat. Som referens användes en professionell elkvalitetsanalysator. Alla uppdragsgivarens krav blev uppfyllda och arbetet kommer att kunna användas i undervisningen.This thesis was ordered by Kalmar Maritime Academy. The request was for a device that could measure active, reactive and apparent power, as well as frequency, voltage, current and cosϕ on a generator. The measured values would be communicated to a PLC for use in a load sharing program between a number of generators in the course Tillämpad elteknik, 15 ECTS. In that course the students constructs a three-generator electric power grid. Included in the request was also to program a load sharing program. The prototype being constructed was based on the Arduino Ethernet, and the communication was enabled by means of the Modbus TCP/IP protocol over Ethernet. A load sharing program was created in the form of a function block which the student could import into the CoDeSys for use in the generator systems. The prototype could measure values with close to the same accuracy as a commercial available instrument that were using the same technique for measuring. The refresh rate was however lower than the commercial available instrument. Communication with the PLC worked without any issues. No full-scale testing could be done since no course was held during the final stages of the thesis, however the load sharing program could keep frequency on a single generator alone and worked in a simulated soft environment. Measuring errors occurred when measuring a capacitive load. When comparing to a commercial available clamp meter, the same errors occurred. As a reference a professional power and energy quality analyser was used. All the requests were fulfilled and the result of this thesis will be used in the educational programme at the Academy.

Projektet går ut på att ersätta den befintliga styrningen av en DC-generator för 1200 kV med en fjärrstyrning från kontrollrummet via optolänk. Den nya styrningen ska utgöras av ett PLC-system (Programmable Logic Controller) som manövreras med hjälp av ett HMI – Human Machine Interface. Bakgrunden till projektet härrör från att den befintliga styrutrustningen är opålitlig samt styrs i en farlig miljö. Rapporten går igenom hur befintlig styrutrustning fungerar samt dess ingående komponenter, hur ett PLC-system fungerar med dess bakgrund och olika programmeringsspråk. Även programmeringen och byggnationen av det nya systemet avhandlas. I slutet av rapporten ges en genomgång av de provkörningar som utförts för att säkerställa att alla funktioner fungerar som tänkt. Resultat av provkörningarna ges och diskussion förs kring projektet. Projektet är utfört åt högspänningsgruppen på RISE i Borås som använder generatorn bland annat vid kalibrering av spänningsdelare. Det nya styrsystemet innefattar alla av den tidigare styrutrustningens funktioner och några nya funktioner så som överströms- och överspänningsskydd vilka slår från spänningsmatningen om dessa begränsningar överskrids. Att styrutrustningen nu är placerad i kontrollrumsmiljö gör att operatören kan hantera utrustningen utan att vara i närheten av farlig spänning.The report aims to replace the current control equipment for a DC-generator for 1200 kV by remote control from control room through optical fibre link. The new control will be a PLC system controlled by a HMI – Human Machine Interface. The background to the project is that the existing control equipment is unreliable and controlled in a dangerous environment. The report shows how the current control equipment works and its constituent components, how a PLC-system works with its background and different programming languages. This report will also describe how the programming and building of the hardware are done. In the end of this report are going through a test run to confirm that the system is working properly. Result of the test run are given and some discussion. The project is initiated by the high voltage group at RISE in Borås, who are using the DC-generator for instance while calibrating voltage dividers. The new control system contains all of the functions from the earlier control system but also some new functions such as overcurrent and overvoltage protection who turns off power supply if the limits are exceeded. The control system is now located in the control room so that the operator can use the system without being close to high voltage.

An important consideration in discrete event dynamic systems control theory is the selection of a suitable modeling formalism that can capture the complex characteristics of the system and the capability to automatically synthesize a controller based on the system model. Net condition event systems are well suited for modeling complex discrete event dynamic systems owing to their input and output structure, which effectively captures the behavior of the physical devices to be monitored and/or controlled. To date, net condition event systems control models have not been extensively applied to highly automated manufacturing systems and there are few guidelines on how to automatically generate Programmable Logic Controller programming languages from net condition event systems models. This research automatically converted net condition event systems control models into Programmable Logic Controller programming language and evaluated the applicability of the proposed methodology in highly automated manufacturing systems using HAS-200 as a test bed.

Der volle Inhalt der QuelleAnnotation:
The Programmable Logic Array (PLA) has been widely used in the design of VLSI circuits and systems because of its regularity, flexibility, and simplicity. The equivalence problem is typically to verify that the final description of a circuit is functionally equivalent to its initial description. Verifying the functional equivalence of two descriptions is equivalent to proving their logical equivalence. This problem of pure logic is essential to circuit design. The most widely used technique to solve the problem is based on Binary Decision Diagram or BDD, proposed by Bryant in 1986. Unfortunately, BDD requires too much time and space to represent moderately large circuits for equivalence testing. We design and implement a new algorithm called the Cover-Merge Algorithm for the equivalence problem based on a divide-and-conquer strategy using the concept of cover and a derivational method. We prove that the algorithm is sound and complete. Because of the NP-completeness of the problem, we emphasize simplifications to reduce the search space or to avoid redundant computations. Simplification techniques are incorporated into the algorithm as an essential part to speed up the the derivation process. Two different sets of heuristics are developed for two opposite goals: one for the proof of equivalence and the other for its disproof. Experiments on a large scale of data have shown that big speed-ups can be achieved by prioritizing the heuristics and by choosing the most favorable one at each iteration of the Algorithm. Results are compared with those for BDD on standard benchmark problems as well as on random PLAs to perform an unbiased way of testing algorithms. It has been shown that the Cover-Merge Algorithm outperforms BDD in nearly all problem instances in terms of time and space. The algorithm has demonstrated fairly stabilized and practical performances especially for big PLAs under a wide range of conditions, while BDD shows poor performance because of its memory greedy representation scheme without adequate simplification.

A temperature sensor is a device to measure the temperature through an electrical signal. It requires a thermocouple or resistance temperature detectors (RTD) and will interface with a programmable logic controller (PLC). A temperature transmitter is a device that connects to a temperature sensor to transmit the signal elsewhere for monitoring and control purposes that its role is to convert the temperature sensor's signal to a 0-10V DC voltage in the PLC. The PLC voltage signal setting is compared to the temperature deviation after the Proportional Integral Derivative (PID) operation. Then, the system will issue a temperature control signal to achieve the cooling system voltage control so that it implements continuous monitoring and temperature control. The temperature control system in the industrial field has a certain value that it is an important factor for controlling temperature. A certain value of the temperature of the desired environment has to be set with a minimum and maximum set-point temperature which is suitable for that environment and the set-point value can be variable and can be changed with Human Machine Interface (HMI) easily.

In this work I deal with the project of an automated robotic bartender, whose task is to show model concepts such as virtual commissioning, digital factory or industry 4.0. The work resolves two parts (cells) for the overall construction. Individual cells are solved from the design and realization of the construction through the virtual verification of operation to the design and realization of the control itself for the given cells. The construction solution was created in SolidEdge ST10. Virtual verification will be solved in the Tecnomatix Process Simulate program and the implementation of PLC and HMI control by Siemens is programmed in the TIA Portal. Wiring diagrams were drawn in the student version of the EPLAN design environment. Other colleagues work on other parts of the barman project.

My diploma thesis deals with the design and production of the first of the two parts of a device for classifying goods. This device needs two programmable logic controllers (hereafter PLCs), produced by Phoenix Contact, to complete these activities. These controllers are interconnected. One part of the solution, which is described in my thesis in detail, deals with the communication between these controllers, the design of optimalization of methods of classifying goods, which is important for the operation of the whole device and visualization realization. The PLCs are programmed in PC worx software and the visualisation has been made using the Visu+ programme produced by Phoenix Contact. The outcome of my thesis is a device, which, after setting up of the parameters, works independently and is completely controlled by a HDMI touch screen. This thesis has been supported by the Czech Ministry of Education in the frame of MSM 0021630529 Research Intention Inteligent Systems in Automation.

The Target Positioning Sensor (TPS) is used by cranes to locate containers in ports and on cargo ships. The reliability of the communication network between the TPS and the Programmable Logic Controller (PLC) is important to optimise the productivity of the container terminal. Lost data messages between the network devices will lead to delays and production loss for the terminal. The main goal of this thesis project is to make the Ethernet-based network between the TPS and the PLC more reliable. The current sensor network protocol uses the User Datagram Protocol (UDP), and the project aims to replace that with the Transport Control Protocol (TCP). This includes designing a new message handling application and performing case studies on how to best handle compatibility issues between the TPS and the PLC, to improve the longevity of the application. The case studies led to considering an adaptable behaviour toward future software updates in different parts of the network. An application which used TCP to communicate between a PC and a PLC was developed, intended to be used as a reference during future integration into the actual sensor network. The TCP application works but needs to be improved before being implemented in a real system. In addition, the project also looked into Time-Sensitive Networking, which is a method of increasing link capacity and reliability in time-sensitive network implementations. This was done through a literature study on the IEEE Time-Sensitive Networking Standard, which showed that the application of the standard could be beneficial if more sensors are added to the network of if the sampling frequency of the TPS is increased.

Approved for public release; distribution is unlimitedThe contribution of this thesis is the development of a CAD (computer aided design) tool for current mode multiple-valued logic (MVL) CMOS circuits. It is only the second known MVL CAD tool and the first CAD tool for MVL CMOS. The tool accepts a specification of the function to be realized by the user, produces a minimal or near-minimal realization (if such a realization is possible), and produces a layout of a programmable logic array (PLA) integrated circuit that realizes the given function. The layout is in MAGIC format, suitable for submission to a chip manufacturer. The CAD tool also allows the user to simulate the realized function so that he/she can verify correctness of design. The CAD tool is designed also to be an analysis tool for heuristic minimization algorithms. As part of this thesis, a random function generator and statistics gathering package were developed. In the present tool, two heuristics are provided and the user can choose one or both. In the latter case, the better realization is output to the user. The CAD tool is designed to be flexible, so that future improvements can be made in the heuristic algorithms, as well as the layout generator. Thus, the tool can be used to accommodate new technologies, for example, a voltage mode CMOS PLA rather than the current mode CMOS currently implemented.

The majority of the power generated today is produced using fossil fuels,emitting carbon dioxide and other pollutants every second. Also, fossil fuels will eventually run out. For the increasing worldwide energy demand, the use f reliable and environmentally beneficial natural energy sources is one of the biggest challenges. Alongside wind and water, the solar energy which is clean, CO2-neutral and limitless, is our most valuable resource.
Concentrated solar power (CSP) is becoming one of the excellent alternative sources for the power industry. The successful implementation of this technology requires the efficient design of tracking and operation system of the CSP solar plants. A detailed analysis of components needed for the design of cost-effective and optimum tracker for CSP solar systems is required for the power plant modeling, which is the primary subject of this thesis. A comprehensive tracking and operating system of a parabolic trough solar power plant was developed focusing primarily on obtaining optimum and cost effective design through the simplified methodology of this work. This new model was implemented for a 50 kWe parabolic trough solar power plant at University of South Florida, Tampa.

Increasingly, goods and services are purchased over the Internet without any form of physical currency. This practice, often called e-commerce, offers sellers and buyers a convenient way to trade globally as no physical currency must change hands and buyers from anywhere in the world can browse online store fronts from around the globe. Nevertheless, many transactions still require a physical presence. For these sorts of transactions, a new technology called Near Field Communication has emerged to provide buyers with some of the conveniences of e-commerce while still allowing them to purchase goods locally. Near Field Communication (NFC), an evolution of Radio-Frequency Identification (RFID), allows one electronic device to transmit short messages to another nearby device. A buyer can store his or her payment information on a tag and a cashier can retrieve that information with an appropriate reader. Advanced devices can store payment information for multiple credit and debit cards as well as gift cards and other credentials. By consolidating all of these payment forms into a single device, the buyer has fewer objects to carry with her. Further, proper implementation of such a device can offer increased security over plastic cards in the form of advanced encryption. Using a testing platform consisting of commercial, off-the-shelf components, this dissertation investigates the security of the NFC physical-layer protocols as well as the primary NFC security protocol, NFC-SEC. In addition, it analyzes a situation in which the NFC protocols appear to break, potentially compromising sensitive data. Finally, this dissertation provides a proof of security for the NFC-SEC-1 variation of NFC-SEC.

Autotube är ett företag baserat i Varberg som utvecklar och producerar luft- och vätskelösningar främst inom bilindustrin. På senare tid har biltillverkarna skiftat till högre bränsletryck i bensindrivna förbränningsmotorer vilket har lett till att företagets produktutvecklingsavdelning saknar testutrustning för att utveckla nya produkter vilket i sin tur har lett till att företaget köpt tjänsten från extern leverantör. Kostnaderna och den bristande insynen i trycktester hos extern leverantör har lett Autotube att investera i ny utrustning och bedriva framtida tester i företagets lokaler. Ambitionen är att testanläggningen ska kunna genomföra tryckpulser och sprängprover både för produktutveckling och stickprov. Det övergripande syftet med examensarbetet är att programmera PLC logiken, designa HMI-panelen och skapa en elektriskt överförbar rapport efter genomfört testutförande. Under projektets progression visade studier och företagets empiriska kunskaper att resultatet från testanläggningen karakteriseras av tre nyckelparametrar; funktionsduglighet, realtidsövervakning och datahantering. Varje kategori har givetvis flera underkategorier som adderar värde till nyckelparametrarna. För funktionsduglighet krävs pålitlig hårdvara som klarar av att vara driftsatt under lång tid utan avbrott. Dock om ett avbrott från yttre faktorer skulle inträffa behöver testanläggningen programmeras för att spara data och undvika att testresultaten raderas. För att undvika irritation och handhavandefel bör användargränssnittet vara utformad efter målgruppens behov och mängden information bör begränsas. God realtidsövervakning ställer krav på lättåtkomlig information både vid testanläggningen och på distans vilket ökar möjligheten att läsa av testutförandes värden oberoende av vart användaren befinner sig. För att minska användarens arbetsbelastning bör varningssignaler som indikerar när testanläggningen inte utför önskvärt arbete användas. Datahantering bör ske automatiserat för att tillse att rätt data lagras och att den mänskliga faktorn kringgås. Flertalet rapporter under testutförandets förlopp är fördelaktigt för jämförelse av testutförandets olika skeden vilket ökar insikten om vad som skett när och möjliggör en djupare analys av testutförandet. Det genomförda arbetet har analyserat olika alternativ och använt litteratur relevant till nyckelparametrarna tillsammans med kontinuerlig återkoppling från företagets tekniker för att skapa mjukvaran till testanläggningen. Resultatet är en pålitlig anläggning med skräddarsydd realtidsövervakning och automatisk datahantering.Autotube is a company based in Varberg that develops and produces air- and fluid solutions primarily to the automotive industry. Recently the automotive manufacturers have increased the fuel injection pressure in petrol engines which has led to the absence of proper test equipment which limits the company’s product development department as pressure test has to be bought by a third-party company. The costs and lack of insight in the pressure tests that is associated with purchasing the service from a third part company has led Autotube to invest in new equipment that will allow the company to do future tests in-house. The ambition is to perform pressure pulsation tests and burst tests for both product development and production samples. The general purpose of the thesis is to program the PLC logic, design the HMI-panel and to create and electrically transferrable report after test completion. During the progression of the project studies and the company’s empirical knowledge showed that the result from a test facility is characterized primarily by three key parameters; functionality, real time monitoring and data management. Each category includes several subcategories that adds value to each key parameter. Functionality requires reliable hardware that can stay commissioned for extended periods of times without Interruption. However, if interruptions do occur it is important that the data from the ongoing test is saved so that data is not lost. To avoid irritation and mishandling it’s important to design the user interface according to the needs of the users and to avoid excessive information that is not vital for the result. A proper real time monitoring solution requires that information is easily available both at the location of the test facility and at distance in order to enable to user to act no matter where the user is located. Warning signals that indicate when the test facility does not perform as expected should be used in order to reduce the workload. Data management should be automatic in order to store the correct data and prevent errors caused by the human factor. Several reports should be used during the test as it allows the user to compare the data in the different test stages which improves the insight and analysis capability of the performed test. The performed work has analysed different alternatives and used literature relevant to the key parameters combined with continuous feedback from the company’s technicians in order to create the software for the test facility. The result is a reliable facility with tailored real time monitoring and automatic data management.

Thesis (MScEng (Mechanical and Mechatronic Engineering))--University of Stellenbosch, 2010.ENGLISH ABSTRACT: This work considers the control of reconfigurable assembly systems using a welding assembly system as a case study. The assembly system consists of a pallet magazine, a feeding system, an inspection and removal system, a welding system and a conveyor. The aim of the work is to compare PC and PLC as controllers, as well as to compare two different approaches to reconfigurable control. The control system of the pallet magazine was developed using a PC and a PLC. The PC control was programmed using Visual C#, while the PLC was programmed in Ladder Logic using Siemens S-300 STEP7. The two controllers were compared based on the attributes that measure the quality of a controller's software, which include its capability, availability, usability and adaptability. The approaches to reconfigurable control considered were the agent-based methodology and the IEC 61499 distributed control methodology, both of which were applied to the feeding system. The agent-based control system was implemented using the JADE agent platform, while the IEC 61499 distributed control system was implemented using the FBDK software kit. These two methods were compared based on the characteristics of a reconfigurable system, which include the system's modularity, integrability, convertibility, diagnosability, customization and scalability. The result obtained in comparing the PC to the PLC shows that the PLC performs better in terms of capability, availability and usability, while the PC performs better in terms of adaptability. Also, the result of the comparison between the agent-based control system and the IEC 61499 distributed control system shows that the agent-based control system performs better in terms of integrability, diagnosability and scalability, while the IEC 61499 distributed control system performs better in terms of modularity and customization. They are, however, on a par in terms of convertibility.
AFRIKAANSE OPSOMMING: Hierdie werk beskou die beheer van herkonfigureerbare monteringstelsels met 'n sweismonteringstelsel as gevallestudie. Die monteringstelsel bestaan uit 'n paletmagasyn, 'n voerstelsel, 'n inspeksie-en- verwyderingstelsel, 'n sweisstelsel en 'n voerband. Die mikpunt van die werk is om persoonlike rekenaars (PCs) en programmeerbare-logikabeheerders (PLCs) as beheerders te vergelyk, asook om twee verskillende benaderings tot herkonfigureerbare beheer te vergelyk. Die beheerstelsel van die paletmagasyn is ontwikkel met 'n PC en 'n PLC. Die PC-beheer is in Visual C# geprogrammeer, terwyl die PLC in leerlogika met Siemens S-300 STEP7 geprogrammeer is. Die twee beheerders is vergelyk in terme van die eienskappe wat die kwaliteit van 'n beheerder se sagteware meet en sluit in vermoë, beskikbaarheid, bruikbaarheid en aanpasbaarheid. Die benaderings tot herkonfigureerbare beheer wat oorweeg is, is die agent-gebaseerde metodologie en die IEC 61499 verspreide-beheermetodologie. Beide is op die voerstelsel toegepas. Die agent-gebaseerde beheerstelsel is geïmplementeer met behulp van die JADE agent-platform, terwyl die IEC 61499 verspreide stelsel geïmplementeer is met behulp van die FBDK sagteware-stel. Hierdie twee metodes se vergelyking is gebaseer op die eienskappe van 'n herkonfigureerbare stelsel, waarby die stelsel se modulariteit, integreerbaarheid, diagnoseerbaarheid, pasmaakbaarheid en skaleerbaarheid ingesluit is. Die resultate wat in die vergelyking tussen die PC en PLC verkry is, toon dat die PLC beter vaar in terme van vermoë, beskikbaarheid en bruikbaarheid, terwyl die PC beter vaar in terme van aanpasbaarheid. Die resultaat van die vergelyking tussen die agent-gebaseerde beheerstelsel en die IEC 61499 verspreide beheerstelsel wys dat die agent-gebaseerde beheerstelsel beter vaar in terme van integreerbaarheid, diagnoseerbaarheid en skaleerbaarheid, terwyl die IEC 61499 verspreide beheerstelsel beter vaar in terme van modulariteit en pasmaakbaarheid. Hulle is egter vergelykbaar in terme van omskepbaarheid.

The traditional processes for treatment of hazardous waste are questionable for it generates other wastes that adversely affect people s health. As an attempt to minimize these problems, it was developed a system for treatment of hazardous waste by thermal plasma, a more appropriate technology since it produces high temperatures, preventing the formation of toxic pollutants to human beings. The present work brings out a solution of automation for this plant. The system has local and remote monitoring resources to ensure the operators security as well as the process itself. A special attention was given to the control of the main reactor temperature of the plant as it is the place where the main processing occurs and because it presents a complex mathematical model. To this, it was employed cascaded controls based on Fuzzy logic. A process computer, with a particular man-machine interface (MMI), provides information and controls of the plant to the operator, including by Internet. A compact PLC module is in charge of the central element of management automation and plant control which receives information from sensors, and sends it to the MMI

In this thesis we propose an abstraction based certification technique for Java programs which is based on rewriting logic, a very general logical and semantic framework efficiently implemented in the functional programming language Maude. We focus on safety properties, i.e. properties of a system that are defined in terms of certain events not happening, which we characterize as unreachability problems in rewriting logic. The safety policy is expressed in the style of JML, a standard property specification language for Java modules.
In order to provide a decision procedure, we enforce finite-state models of programs by using abstract interpretation.
Starting from a specification of the Java semantics written in Maude, we develop an abstraction based,
finite-state operational semantics also written in Maude which is appropriate for program verification.
As a by-product of the verification based on abstraction, a dependable safety certificate is delivered which consists of a set of rewriting proofs that can be easily checked by the code consumer by using a standard rewriting logic engine. The abstraction based proof-carrying code technique, called JavaPCC, has been implemented and successfully tested on several examples, which demonstrate the feasibility of our approach.
We analyse local properties of Java methods: i.e. properties of methods regarding their parameters and results. We also study global confidentiality properties of complete Java classes, by initially considering non--interference and, then, erasure with and without non--interference. Non--interference is a semantic program property that assigns confidentiality levels to data objects and prevents illicit information flows from occurring from high to low security levels. In this thesis, we present a novel security model for global non--interference which approximates non--interference as a safety property.Alba Castro, MF. (2011).

This Graduation Theses dissertate about a creation of a drawing documentation at the professional CAE EPLAN Electric P8 system. One original solution of a remote control and of motor-generator monitoring with a mobile phone, short SMS-aided in this case, was used as an example of the drawing documentation. As has allready been noted in previous Bachelor Thesis, this application can be use not only for a remote control of a motor-generator, but this solution is suitable for other electric devices too, which are out of reach of an attendance for example. In our case a generator with 6kVA power is concerned with rated output voltage 230Vac and rated current 25A. The system of a remote control has the advantage that it is created from standard components (electric instruments, a PLC – programmable automat, a GSM modem, an operating panel and the respective program in the PLC).

Os dispositivos lógicos programáveis pertencentes à família APEX 20K, são configurados no momento da inicialização do sistema com dados armazenados em dispositivos especificamente desenvolvidos para esse fim. Esta família de FPGAs possui uma interface otimizada, permitindo também que microprocessadores os configure de maneira serial ou paralela, síncrona ou assíncronamente. Depois de configurados, estes FPGAs podem ser reconfigurados em tempo real com novos dados de configuração. A reconfiguração em tempo real conduz a inovadoras aplicações de computação reconfigurável. Os dispositivos de configuração disponíveis comercialmente, limitam-se a configurar os FPGAs apenas no momento da inicialização do sistema e sempre com o mesmo arquivo de configuração. Este trabalho apresenta a implementação de um controlador de configuração capaz de gerenciar a configuração e reconfiguração de múltiplos FPGAs, a partir de vários arquivos distintos de configuração. Todo o projeto é desenvolvido, testado e validado através da ferramenta EDA Quartus II, que propicia um ambiente de desenvolvimento integrado de projeto, compilação e síntese lógica, simulação e análise de tempo.The APEX 20K programmable logic devices family, are configured at system power-up with data stored in a specific serial configuration device. This family of FPGAs contain an optimized interface that permits microprocessors to configure APEX 20K devices serially or in parallel, and synchronously or asynchronously. After configured, it can be reconfigured in-circuit by resetting the device and loading new data. Real-time changes lead to innovative reconfigurable computing applications. The commercial available configuration devices limit to configure the APEX 20K devices only on the system power-up and always with the same configuration data file. This work shows a configuration controller implementation that can manage the configuration and reconfiguration of several FPGAs from multiple configuration files. The entire project is developed, tested and validated through the EDA tool Quartus II, that provide a integrated package with HDL and schematic design entry, compilation and logic synthesis, full simulation and worst-case timing analysis.

La métamorphose du risque professionnel puise ses sources dans la mutation de la représentation du risque professionnel factuel qui a permis la consécration de la notion de maladie professionnelle. Substituée à l’accident du travail comme centre de gravité du droit des risques professionnels, elle devient le point d’impulsion d’une réflexion nouvelle du concept juridique de risque professionnel entraînant la mutation du risque professionnel pris en charge. Cette métamorphose, dans le droit de la Sécurité sociale, permet la réactivation de l’obligation de sécurité de l’employeur qui irradie le droit du travail et entraîne l’affirmation du droit à la santé et à la sécurité des travailleurs. Partant, la réparation des atteintes à la santé du travailleur est considérablement étendue. Néanmoins, cette construction se heurte à des obstacles de taille, et s’accompagne d’incohérences, qu’il faut dépasserThe metamorphosis of occupational hazard has its sources in the mutation of the representation of factual occupational hazard that led to the consecration of the notion of occupational disease. Substituted for the occupational accident as the centre of gravity of the occupational hazards law, it becomes the impetus for a new reflection about the legal concept of occupational hazard causing the mutation of occupational hazard taken charge of. This metamorphosis in the Social Security law, allows the reactivation of the employer's duty to ensure security that radiates labour law and causes the assertion of the workers’ right to health and safety. Therefore, the compensation of damages to workers’ health is considerably extended. However, this construction is fraught with obstacles, and is accompanied by inconsistencies that must be overcome

Il consiste dans la possibilité pour le juge du siège de prendre une décision de culpabilité et d'ajourner le prononcé de la peine, lorsque le reclassement du coupable est en voie d'être acquis, le dommage causé est en voie d'être réparé et le trouble résultant de l'infraction va cesser. Ce mécanisme introduit une distinction formelle entre la responsabilité pénale et la peine. Cette dissociation formelle permet d'identifier chaque composante du jugement et d'en définir précisément le contenu. L'ajournement rappelle ainsi la spécificité du prononcé de la peine, de la culpabilité et de l'imputabilité. Au-delà de cette césure formelle et substantielle, l'ajournement permet d'envisager une recomposition du processus pénal autour de ces éléments. Ainsi, l'ajournement favorise une reconnaissance de culpabilité au confluent des compétences du juge du siège et du procureur. Ensuite, le délai d'ajournement peut être consacré à la question de l'imputabilité. Enfin, le juge du siège peut à la fois prononcer une peine et contrôler son application.

Issues de la pratique des affaires aux Etats-Unis, les joint ventures sont devenues sous l'influence de la pratique internationale des instruments de coopération internationale permettant d'organiser le contrôle conjoint d'une entreprise dans l'intérêt commun de deux ou plusieurs partenaires indépendants. L'étude du montage de la joint venture dans la pratique (première partie) permet de saisir l'originalité du schéma contractuel dont la répétition a permis aux arbitres de dégager des règles d'interprétation spécifiques. Le complexe contractuel qui est à sa base (Titre 1) est unifié grâce au contrat de joint venture qui fait figure de contrat cadre de coopération (Chapitre 1), et exécuté au moyen de contrats d'application interdépendants (Chapitre 2). Les structures de l'entreprise (Titre 2) incitent à distinguer les joint ventures personnalisées dans lesquelles l'opération est conduite par le truchement d'une personne morale distincte (Chapitre 1), et les joint ventures non personnalisées qui demeurent contractuelles ou prennent la forme d'une société en vertu du droit compétent (Chapitre 2). L'unité de l'opération est assurée par une technique contractuelle particulière au terme de laquelle le groupement personnalisé est contractualisé pour permettre le contrôle conjoint de l'entreprise, le groupement non personnalisé organisé pour faire face à sa durée et à sa complexité. L'analyse de l'accueil de la joint venture dans l'ordre international (deuxième partie) conduit à constater que ce schéma contractuel original s'est répandu tout en étant soumis aux droits nationaux et non du fait de son autonomie par rapport à ces derniers. L'institutionnalisation de la joint venture (Titre 1) a permis à de nombreux pays à économie dirigée de s'ouvrir à l'investissement étranger (Chapitre 1), et offre aujourd'hui encore dans plusieurs Etats un cadre juridique pour la réalisation d'un investissement (Chapitre 2). En l'absence de réglementation spécifique, la reconnaissance de la joint venture (Titre 2) dépend de la détermination du droit applicable (Chapitre 1) et de l'intervention des lois de police (Chapitre II). L'application des méthodes traditionnelles de détermination du droit compétent doit ainsi être adaptée à l'existence d'un complexe contractuel et souvent d'une société qui est forcément qualifiée et régie par un droit étatique, tandis que les lois de police sont appelées, notamment en droit de la concurrence et en droit du travail, à prendre en considération la fonction singulière de la joint venture : le contrôle conjoint d'une entreprise.

Invitant à réfléchir sur les rapports entre droits spéciaux et droit commun, Droit et Economie, intérêt général et intérêts particuliers, l'étude du droit de la concurrence et du droit commun. Des obligations est envisagée de façon positive et prospective. La déconstruction révèle un entrecroisement inéluctable, à travers la résurgence rassurante du droit commun des obligations dans le droit de la concurrence et la pénétration différenciée de ce dernier dans le droit des obligations. La reconstruction subséquente repose sur une répartition des missions et des échanges mutuels entre ces droits. Sollicitant les vertus fédératrices du droit commun et les vertus constructives de la spécialisation, la complémentarité recherchée des deux disciplines requiert un double mouvement: la canalisation du droit de la concurrence par le droit commun des obligations (limite et modèle du droit spécial) ; la régénération de ce dernier par le droit spécial (aiguillon et préfiguration du droit commun).

Cette recherche vise à matérialiser la notion d'uniformité dans le droit public français en dépassant l'enjeu territorial, simple révélateur de l'importance de l'uniformité, mais qui, en aucun cas, ne l'explique ou ne la fonde. Par ailleurs, l'analyse d'une telle notion ne peut s'opérer à rebours ; le procès instruit contre l'uniformité n'apparaît pas suffisant pour comprendre sa signification et son importance. De plus, les altérations ou les exceptions à une telle notion ne rendent pas l'uniformité non effective. L'uniformité est liée au pouvoir politique, à cette forme si particulière constituée par l' État. Elle dépend de l'État moderne apparu à partir du XVIe siècle. Cependant, la thèse tocquevillienne d'une continuité entre l'Ancien régime et la Révolution ne sera pas reprise. La compréhension de l'uniformité requiert de la dissocier de l'égalité et son intégration dans un rapport vertical au pouvoir. L'uniformité s'inscrit également dans un rapport horizontal qui apparaît seulement avec l'État révolutionnaire. Ce dernier apporte une unité, au et du pouvoir, mais place les personnes dans un rapport égalitaire, à travers des dénominations abstraites, neutres et impersonnelles, telles que celles de "citoyen" ou d' "élève". Cette dimension horizontale ressort notamment à travers l'action de l'État. En ce sens, l'uniformité commande les grandes notions du droit administratif français : "acte administratif", "fonctionnaire", "usager", le "service public" et ses problématiquesThe uniformity is recently at the center of debate about territorial organisation of the Republic. Often found in the statent concerning the local communities, the uniformity is only perceveid as simple assertion. However, the uniformity is not a normal word, it is a notion caractherized of the modern state and its work. Its approach needs to go beyond the territorial stakes and reposition it in the center of thought about the French public law
