Application of "SIL" integrated circuits for pressure vessel filling
Červený, Patrik ; Steklý, Jakub (referee) ; Štohl, Radek (advisor)
The thesis focuses on the application of process safety according to SIL for pressure vessel filling in the energy industry specifically in a petrochemical plant for oil processing. The thesis includes a brief research of IEC 61511 and IEC 61508 standards that are used here, definition of pressure vessel, SIL analysis procedures, HAZOP hazard and operability study, process simulation in TIA portal and developed an application for error generation in C# using S7.Net library. The application generates faults that may commonly occur in operation and the process simulation responds in a safe manner. A HAZOP and SIL analysis of the process was performed in collaboration with McDermott and the results were summarized. Subsequently, a process simulation with applied protection was created.

Semiautomatic crimping machine
Nosek, Jakub ; Stibor, Karel (referee) ; Štohl, Radek (advisor)
This thesis deals with the design, creation and testing of a new automated machine for the production of ureteral catheters for a company producing medical equipment. The work is a continuation of the diploma thesis of a student of the College of Polytechnics Jihlava, whose work only concerned the design of the mechanical part of the machine and the analysis of the actual manual production process.

Automatic documentation tool for PLC software
Navrátil, Jan ; Štohl, Radek (referee) ; Petyovský, Petr (advisor)
This thesis focuses on implementing a tool for automatic generation of diagrams from annotated source code written in Structured Text for PLC applications. The aim is to streamline the documentation process of software projects by enabling developers to automatically generate diagrams that describe the structure and behavior of their applications. The thesis further explores existing tools for diagram creation and their capabilities. Based on this exploration, a compiler is designed and implemented, which extracts relevant information from the code and generates diagrams in the standardized graphical language UML. The result is an implemented tool that allows developers to easily create and update diagrams of their applications, contributing to a faster and more accurate documentation process.

Visualization of the production line by FactoryTalk Optix
Sýkora, Ondřej ; Knobloch, Tomáš (referee) ; Štohl, Radek (advisor)
This thesis is focused on creating a visualization in the new FactoryTalk Optix environment for the Automatic Bartender and Coaster Press machines. The first part is dedicated to the general rules of HMI visualization, the main concepts are based on the ANSI/ISA-101.01.-2015 standard. The second part is devoted to the analysis of visualization tools and software and their comparison and assessment of suitability of use for Allen-Bradley PLC. The final work is devoted to the design and implementation of visualization in the FactoryTalk Optix environment. In the fifth part, changes to machines, PC and PLC programs are analyzed. Also mentioned here is the superior FactoryTalk Batch control tool and how the visualization and editing of the PLC program is prepared for it. The last part is dedicated to editing the user manual.

HMI for a 3D milling machine using FactoryTalk Optix
Uher, Adam ; Foukal, Roman (referee) ; Štohl, Radek (advisor)
The thesis focuses on the design and implementation of an HMI (Human Machine Interface) for 3D milling machine. Basic visualization rules, best practises, principles of ergonomic design, and the creation of user interfaces are described. Visualization tools for the LOGIX PLC series are outlined, which can be utilized in HMI development. Following the guidelines and specified requirements in this paper, a design for HMI is created using the FactoryTalk Optix visualization tool. Changes to the functional safety and PLC program are identified and implemented. Subsequently, the visualization of the milling machine is carried out and the functions of the new system are subjected to testing.

Power Line Communication for Home Automation Applications
Hromádka, Michal ; Štohl, Radek (referee) ; Fiedler, Petr (advisor)
This thesis describes the design of a modem for a communication over residential power lines. First part is focused on the history, suitable frequency bands, modulation techniques and mainly on the selection of the optimal modem device. Second section contains the description of the hardware design of the modem itself and clarifies the implementation of the PLC module to be used as a communication interface for a full residential automation solution. Last chapters of this thesis introduce the communication protocol, design of the software for the ATmega32 MCU and present of the final field testing under real conditions.

Add-on to moto-racing software
Schneiderka, Dominik ; Macho, Tomáš (referee) ; Štohl, Radek (advisor)
The main goal of this bachelor´s thesis was to establish communication with scoreboard via RS-485 and develop application for reporter. Communication with scoreboard was added to existing program Regularity Rally, also main errors were corrected. To ensure correct behavior the existing database was slightly modified. All programs were developed in Microsoft Visual Studio 2017 and written in programming language C#. The database was developed via MySQL.

Desing of supplementary coding switching unit
Štefl, Martin ; Štohl, Radek (referee) ; Fiedler, Petr (advisor)
The diploma thesis is dealing with the area of controlling and safety technology for the railway transportation. The problems of the design and practical realization of an functional sample of switching unit supplying the ends of a track circuit are solved here. The switching unit enables the operation of the train control system. The outline of the design is formed by a power switch operated with a microprocessor. In addition, for the increase in safety the switching unit contains a control processor, which is controlling the right function of a work microprocessor and the failure-free state of a power switch.

Firmware for a pressure sensor with HART interfacel
Čožík, Ondřej ; Štohl, Radek (referee) ; Fiedler, Petr (advisor)
The bachelor thesis deals with draft of firmware for a capacitive sensor with HART communication protocol. At first, it briefly describes the HART protocol (principles of communication, frame structure and connectivity devices on the HART bus). Subsequently attention is paid to capacitive sensor description, method of data processing and communication method of the sensor with HART interface. The final part depicts individual parts of the firmware for the capacitive sensor (such as the method of values reading from A/D converter, data reading/writing from/to external or internal EEPROM or calculation of the measured pressure value, its temperature compensation and corresponding current loop, using D/A converter.
