Full textAvhandlingen börjar med att ge lite bakgrundsinformation för att läsaren att förstå de nuvarande sårbarheten i nätverksanslutna enheter, särskilt när det gäller IT-säkerhet och dataintegritet. Idag övervakande kontroll och datainsamlingssystem använder nätverksanslutna programmerbara styrsystem används allmänt i många branscher och kritisk infrastruktur. Dessa nätverk anslutna enheter har under ökande attacker under en tid av illvilliga angripare (inklusive i vissa fall eventuellt regeringen stöds insatser). Denna avhandling utvärderar för närvarande tillgängliga lösningar för att minska dessa attacker. Baserat på denna utvärdering en ny lösning baserad på Trusted Computing Group (TCG) Trusted Platform Modules (TPM) specifikation föreslås. Denna lösning använder en lätt version av TPM och TCG:s pålitliga dator (RCM) för att uppnå önskad säkerhet. Säkerheten i den föreslagna lösningen utvärderas både teoretiskt och med hjälp av en prototyp. Utvärderingen visar att den föreslagna lösningen bidrar i stor utsträckning för att minska de tidigare observerade sårbarheter när omprogrammering nätverksanslutna enheter. Huvudresultatet av denna avhandling projektet är ett säkert sätt omprogrammering dessa nätverksanslutna enheter så att endast ett giltigt användarnamn framgångsrikt kan omprogrammera enheten och ingen annan kan programmera enheten (antingen att återställa den till ett tidigare tillstånd, kanske med en känd attack vector, eller ännu värre förhindra en giltig användare från programmering av enheten).

Full textThe 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.

Full textThis 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.

Full textAutotube 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.

Full textENGLISH 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.

Nowadays the competition between companies is increasing. In a production system, efficiency, speed and flexibility are important means for cost reductions. The complexity of automation systems has been increasing, which makes necessary the implementation of more efficient control programs, free of errors and easy to maintain. However, in most practical applications the solution of these problems is dependent on designer's experience and doesn t follow a formal methodology, which results in programs with errors and difficulties to understand and maintain, since only the designer understands the adopted solutions. The Supervisory Control Theory (SCT) is a method extensively researched in academic circles for the synthesis of control logic of automated systems. It allows control problems to be solved in a formal way, ensuring a minimally restrictive and no blocking solution that meets the control specifications. However, this theory is not widely used in industrial environments yet, once the methods for implementation of supervisors obtained by TCS are still deficient. Thus, the intention of this Dissertation consists of showing a methodology for implementation of supervisory control in Programmable Logic Controllers (PLCs). In this work, the synthesis of supervisors is made in accordance to local modular approach, which brings the benefits of a formal methodology and allows exploring the modularity of the plant and the control specifications. The implementation is based on an architecture structured in three levels: supervisor, interface and system to be controlled. For the implementation in CLP three different programming languages are applied: the high-level languages Sequential Function Charts (SFC) and Structured Text and the low-level Ladder Diagram language in some parts. The development of the methodology was based on two works: a doctoral thesis by Vieira (2007) and master thesis by Cruz (2011) and brought together the advantages presented in each one of these. To compare the proposed methodology and the two mentioned methods, several tests were made on a manufacturing cell available at PUCPR and simulations on a PLC and computer as well. The results show that the use of the methodology proposed in this work makes possible to implement PLC programs that are able to treat all non-controllable events occurred in the system to be controlled and treat one controllable event by each control cell in the same scan cycle. Furthermore, the use of high-level languages results in a program of easier interpretation and maintenance, also enabling reutilization of codes. In this work some problems related to CLPs implementations are also showed and proposals for solving them are presented, as properties as well that, if accepted, ensure that the problem does not occur.
Hoje em dia a competitividade entre as empresas está cada vez maior. Em um sistema de produção, a eficácia, a velocidade e a flexibilidade são importantes, pois significam redução de custos. Os sistemas de automação atuais estão cada vez mais complexos, justificando a necessidade de programas de controle mais eficientes, sem erros e de fácil manutenção. Entretanto, na maioria das aplicações práticas a solução destes problemas é feita com base na experiência do projetista, não seguindo uma metodologia formal, o que resulta em programas com erros e de difícil entendimento e manutenção, uma vez que só o projetista entende perfeitamente as soluções adotadas. A Teoria de Controle Supervisório (TCS) é um método para a síntese da lógica de controle de sistemas automatizados. Ela permite que problemas de controle sejam solucionados de modo formal, garantindo uma solução minimamente restritiva e não bloqueante e que atenda às especificações de controle. Entretanto, esta teoria ainda não é amplamente adotada em ambientes industriais, sendo a carência de métodos de implementação dos supervisores obtidos via TCS um elemento que contribui para que isso aconteça. Assim, esta dissertação se propõe a apresentar uma metodologia de implementação de controle supervisório em Controladores Lógicos Programáveis (CLPs). Neste trabalho, a síntese de supervisores é feita de acordo com a abordagem modular local, que traz os benefícios de uma metodologia formal e ainda permite explorar a modularidade da planta e das especificações de controle. A implementação é baseada numa arquitetura estruturada em três níveis: supervisor, interface e sistema a ser controlado. Para a implementação em CLP são empregadas três linguagens distintas de programação, as linguagens de alto nível Sequential Function Charts (SFC) e Structured Text, bem como a linguagem Ladder Diagram em algumas partes. O desenvolvimento da metodologia foi baseado em dois trabalhos: a tese de doutorado de Vieira (2007) e a dissertação de mestrado de Cruz (2011) e permitiu reunir as vantagens apresentadas em cada um destes. Para comparação entre a metodologia proposta e as duas metodologias citadas, foram feitos diversos testes em uma célula de manufatura existente na PUCPR, bem como simulações em CLP e em computador. Os resultados mostram que a metodologia proposta neste trabalho permite a implementação de programas em CLP que, num mesmo ciclo de varredura, são capazes de tratar todos os eventos não controláveis ocorridos na planta e ainda um evento controlável por célula de controle. Além disso, o uso de linguagens de alto nível resulta em um programa de mais fácil interpretação e manutenção, possibilitando ainda o reaproveitamento de códigos. Nesta dissertação também são abordados alguns problemas de implementação da estrutura de controle supervisório em CLPs, apresentando-se propostas para solucioná-los, bem como propriedades que, se atendidas, garantem que o problema não ocorra.

Full textThe 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.

Full textThis Diploma Thesis consists of the construction and control of an experimental automated system. In this system a pneumatic moving piston applies constant pressure to any surface that passes under it. The system includes a pneumatic cylinder, pneumatic valves, a pressure sensor and a Programmable Logic Controller (PLC) to control the system. Also, control via Labview is implemented, to be used for results comparison. The system consists of a proportional control valve, an On/Off valve, a pneumatic cylinder and a specially manufactured system for pressure application that also includes the pressure sensor. There is, also, a voltage amplifier that is used between the output of the pressure sensor and the analog input of the CPU. A random wooden surface passes under the experimental system. The primary purpose of the Diploma Thesis is the PID control of the system using the function module FM 355. The FM 355 module from SIEMENS is a function module that is capable of utilizing hardware PID control and fuzzy control in temperature applications. Also, a very important characteristic of the module is the ability to function even when there is loss of communication with the CPU. The FM 355 module controls the proportional valve, while the On/Off valve is controlled by the PLC CPU. In order for the system to work, the desired pressured to be applied must be chosen. This value is inserted into the CPU and from there it is sent to the FM 355 module. Any movement of the wooden surface that leads to a change of pressure, is monitored by the sensor and the system automatically adjusts to track the surface. Control via Labview implements exactly the same logic as mentioned above and was used to extract very useful conclusions.

Full textThis Diploma Thesis consists of the construction and operation, through the means of programming, of an experimental automated system which includes equipment such as pneumatic cylinders (classic or muscle type), position sensors etc. - combined or independent – and a Programmable Logic Controller (PLC) which controls the functions of the automated system. The programming part is referred to the PLC. The experimental automated system that was constructed is that of a mechanical climber. The climber consists of 4 pneumatic cylinders / artificial muscles, the one end of which is attached to a common body. The other end is attached to a sliding mechanism which allows the movement of the muscles on the surface of the vertical aluminum beams that compose the climbing structure. A small pneumatic cylinder is attached on every sliding mechanism, which is used to stop the sliding of the muscles. The combined and successive outstroke and instroke of the cylinders causes the upward or downward movement of the climber’s body, which mimics in a way the movements of a human body while climbing a ladder. Those functions are designed so that the mechanical climber reaches a desired height, which is set by the user. The climb to the desired height can be executed with four (4) different movement patterns: 1) Climb using only the upper limbs. 2) Climb using only the lower limbs. 3) Climb using the upper and lower limbs simultaneously. 4) Climb using the upper and lower limbs and PID position control. The user can set the desired height and choose one of the four movement routines. During the first three movement patterns, the instroke and outstroke of the cylinders is done with the use of predetermined pressure values. In this way, during those patterns the position control approximates the ON/OFF control theory. During the fourth movement pattern, the climb is executed with the same ON/OFF way but the final position control is done by use of a PID controller. After the completion of a movement pattern, or even during movement, the user can always enable the descendance movement routine which returns the climber to its former position.
