This thesis focuses on creating an application that allows generation of PLC and HMI programs using TIA Openness. The application is programmed to separate logic from graphics, which is beneficial in case of a change of the visuals of the application. Generating programs is possible thanks to the XML transcription or by creating a configuration within the application guide. The generating is done by overwriting source XML files contained in the application library according to the selected configuration. The application was created with Framework Windows Forms in C#. A reference set of device modules has been created for PLC and HMI in the development environment of TIA Portal V15.1. The source XML files, on the basis of which the generating is carried out, were then obtained by exporting a reference set and placed into the application library. With a simulation tool Factory I/O and S-7 PLCSIM it was verified that the generated program is, thanks to the mapping of variables on pins of blocks, fully functional in manual mode. At the same time it was proved that it is possible to generate programs for different devices which signifies the versatile use of this application. The contribution of this work is the significant reduction of time when creating new PLC and HMI programs.

Die Programmierung von SPS-Systemen erfolgt hauptsächlich händisch, obwohl große Teile des Programmcodes sehr ähnlich sind und sich häufig nur durch die eingesetzten Variablen unterscheiden. Der Beitrag befasst sich mit der Entwicklung und Testung einer Codegenerierungssoftware für das TIA Portal, um den Zeitaufwand der Programmierung zu reduzieren und Flüchtigkeitsfehler zu vermeiden.

PID is a prevalent tool of automatic control in both industry and home environment, and PID parameters are often forced to modify because of systematic service on the machines or systems, which is time-costing. The project aims to investigate the possibility of applying neural network and reducing PID configuration in controlling industry process, by means of establishing control models and comparing control performance between conventional PID method and improved PID control based on neural network where two built neural networks are considered as cores to adjust weights which result in the suggested PID parameters. Adaptive learning rate is also applied which is adjusted by the algorithm based on the error changes. Algorithm program is written in Siemens TIA Portal and simulated in Factory I/O. In general, the simulations after analysis have shown that the proposed model has a better performance than conventional PID in terms of steady state, deviations and consistency of control value except tuning time. In the future the author is dedicated to continue improving the mentioned model through quickening learning process, applying better activation function and modifying variable structure and so on.

This paper describes the development of a proof-of-concept application, which can be used to train people in the field of programmable logic controller (PLC) and robot programming. This concept leads to a better understanding, what kind of infrastructure and software packages can be combined, to not only have a visual representation of an industrial like scenario, but also the possibility to use commonly established programming environments such as TIA Portal, to set up a PLC program. In addi-tion, it provides insights on how OPC UA can be used and is suitable for controlling a typical six-axis industrial robot with the help of a PLC.

Vattenkraften är en viktig del av den svenska elförsörjningen och tillgodoser cirka 45 % av det årliga elbehovet i landet. Vattenkraften utnyttjar höjdskillnaden mellan inflödet och utflödet för att driva turbiner och producera el. I Sverige finns omkring 200 dammar med en fallhöjd större än 15 m och för höga nivåer vid någon av dessa skulle leda till ett dammbrott med omfattande konsekvenser. Ett viktigt område som det investeras mycket i idag är dammsäkerhet vilket går ut på att undvika okontrollerade översvämningar av dammen. Kännedom av fallhöjd och flöde är nödvändiga inom vattenkraft för att kunna beräkna producerad effekt och även vid dimensionering av dammar, vattenvägar och generatorer. Mättningar på inflödet till ett vattendrag anses vara mycket komplicerat och tidskrävande däremot kan utflödet genom utskoven beräknas med matematiska samband. Utskov avser öppningar i dammen som används för att avbörda vatten. Det finns således olika typer av utskov och det som påverkar valen är aspekter som kostnad, väderförhållanden, avbördningsförmåga, etc. För att undvika en möjlig överströmning av en damm dimensioneras ofta utskoven med avseende på vilken mängd vatten de bör avbörda. Ett krav som ofta ställs är att det ska vara möjligt att avbörda en vattendrags högsta vattennivå (HHQ). Några av de mest förekommande varianter av kontrollerade utskov i Sverige är valsdammar, luckdammar och bottenutskov.   Nivån i vattenmagasinet mäts upp med hjälp av sensorer som är placerade på olika platser vid dammen och uppmätta höga nivåer leder till att olika larmfunktioner löser ut. Regleringen av vattennivån sker då genom att avbörda vatten på ett kontrollerat sätt genom utskoven.  Genom att simulera regleringsprocessen av vattennivån i en virtuell miljö kan olika scenarier som kan uppstå vid magasinhantering testas på ett ekonomiskt sätt och hitta lämpliga reglerstrategier. Simuleringar är också en av de verktyg lyft fram inom industri 4.0 vilket kan bidra till framtidens lösningar inom automatiseringsprojekt. I arbetet studeras de olika beståndsdelar i ett vattenkraftverk och en tilltänkt metod presenteras för skapning av en virtuell modell av nivåregleringsprocessen i Siemens SIMIT, styrning av modellen via en virtuell PLC-enhet och visualisering av processen på en HMI-skärm. / Hydropower is an important part of the Swedish electricity supply and meets about 45% of the annual electricity needs in the country. Hydropower uses the height difference between inflow and outflow to power turbines and produces electricity. In Sweden, there are about 200 dams with a drop height greater than 15 m, and too high levels at any of these dams would lead to a dam break with extensive consequences. An important area in which a lot is invested today is dam safety, which is about avoiding uncontrolled flooding of the dam. Knowledge of drop height and water flow is necessary for hydropower to calculate the power produced and when dimensioning dams, waterways, and generators. Saturations on the inflow to a watercourse are very complicated and time-consuming, however, the outflow through the spillway can be calculated with mathematical correlations. Spillways refer to openings in the dam that are used to carry away water volumes. Thus, there are different types of spillways, and what influences the choices are aspects such as cost, weather conditions, etc. To avoid possible flooding of a dam, the spillways are often dimensioned with respect to the amount of water they should carry away. A requirement that is often made is that it must be able to carry away the highest water level (HHQ) of a watercourse.  The level in the water reservoir is measured with the help of sensors that are in different places by the dam and measured high levels lead to different alarm functions being triggered. The regulation of the water level then takes place by carrying away water in a controlled manner through the spillway. By simulating the regulation process of the water level in a virtual environment, different scenarios that can arise during reservoir management can be tested in an economical way and find suitable control strategies. Simulations are also one of the tools highlighted in industry 4.0, which can contribute to future solutions in automation projects. In the work, the various components of a hydropower plant are studied, and an intended method is presented for creating a virtual model of the level control process in Siemens SIMIT, controlling the model via a virtual PLC unit and visualizing the process on an HMI screen.
