IEC-104 and MODBUS protocol conversion
Syskov, Mykyta ; Grenar, David (referee) ; Slavíček, Karel (advisor)
IEC 104 and ModbusRTU communication protocols are used for control, measurement and data collection in remote terminal units (RTUs) primarily in industrial automation, especially in the power industry. This bachelor’s thesis deals with methods of data conversion between these protocols. The theoretical part contains introductions to these protocols, followed by a description of proposed methods for mutual mapping of the items of individual protocols. The result of the work are scripts that are written in the Python language. These scripts implement the described designs. The operation algorithms are documented in detail in the practical part. Finally, using the UniPi G110 device and the xS51 extension from UniPi Technology, a demonstration of the functionality of this software solution is presented.

Modernization of laboratory equipment and creation of a laboratory task
Medek, Dominik ; Arm, Jakub (referee) ; Baštán, Ondřej (advisor)
This thesis deals with the creation of a teaching equipment, that will allow students to experience working with a PLC and its peripherals, as well as connecting the laboratory tasks and the PPA course project. The thesis discusses the PPA course, its laboratory exercises and the project. It lays out the requirements for a new teaching equipment, that is then created. Its potential uses are then evaluated and two laboratory exercises are created for which a possible solution is developed. The work also includes the establishment of a laboratory standard that addresses the uniform connector wiring for all laboratory teaching equipment and PLC panels.

Programmable Relay in the Application of Automated Production Tests
Ondruška, Arnošt ; Levek, Vladimír (referee) ; Šťáva, Martin (advisor)
This Bachelor thesis describes the design of a programmable relay and its application in the automation of production tests. First, commercially available, professionally produced relays are presented and selected bachelor and diploma theses related to the issue of automated measurement of electrical quantities are summarized. The thesis presents the design of an automated test workplace containing measuring devices, laboratory sources and other accessories controlled by a programmable relay via RS 232, with minimal human intervention. A block diagram is presented in the work, and individual blocks are subsequently described in detail. The output of the work is the creation of a custom design of a programmable relay and its use in automated measurement and control of the properties of serially produced industrial sources for the energy industry. The test program itself is written in the BASCom-AVR language.

I/O Peripheries for Modbus/TCP server
Mikula, Matej ; Štohl, Radek (referee) ; Macho, Tomáš (advisor)
The thesis focuses on the development of input-output peripherals for a Modbus TCP server. Its goal is to create a functional model of a device with analog and digital inputs and outputs. The device is capable of communicating with the PLC Allen-Bradley Logix series. It can report the state of its inputs, and it is possible to set the value of its outputs. The functionality of the proposed device is verified by creating a simple application for the PLC.

Virtual commissioning of wax model gluing for investment casting
Maňák, Juraj ; Bražina, Jakub (referee) ; Szabari, Mikuláš (advisor)
The thesis deals with the virtual commissioning of a robotic workstation for gluing wax models for investment casting. The theoretical part describes the concept of Industry 4.0 and its main pillars, followed by the technology of investment casting and the entire process from wax mold to casting. The next part summarizes the knowledge of robot programming methods and virtual commissioning. This is followed by a chapter analyzing the current methods of gluing and describing the individual components of a universal workstation.The practical part begins with the design of the robotic workstation, including components such as positioners and grippers, and their subsequent description. The next part focuses on creating a simulation in the Process Simulate software, including the definition of kinematic structures and operations. The thesis also describes the process of virtual commissioning, the use of Robot Studio for real feedback, and the subsequent creation of PLC and HMI in TIA Portal.

Design of a weighing unit for an automatic phenotyping line
Mikuš, Martin ; Věchet, Stanislav (referee) ; Štěpánek, Vojtěch (advisor)
The purpose of this master thesis is the design and realization of a weighing and watering unit for an automatic phenotyping system. The master thesis is structured into several phases. Firstly, a market survey of available control systems for unit operation is conducted, followed by design of conceptual solutions and selection of the most suitable design. Subsequently, the design is optimized and appropriate components are selected for implementation. Finally, the weighing and watering unit itself is implemented and thoroughly tested.

IEC-104 interface for UniPi Patron PLCs
Rylich, Slávek ; Grenar, David (referee) ; Slavíček, Karel (advisor)
The aim of this bachelor's thesis is to design, implement and verify a module that will enable the effective integration of the IEC-104 protocol into an existing PLC controller of the UniPi Patron series. The IEC-104 protocol is a standard in the energy and industrial sectors for reliable and high-speed communication between devices. The implementation of this protocol in the UniPi Patron controller expands its capabilities in the area of data collection and real-time information exchange, which contributes to better monitoring and control of industrial processes. The result of the work is a functional module running on the Unipi Patron PLC controller, which enables reliable communication with control SCADA systems through the IEC-104 protocol, thus contributing to the expansion of the capabilities of this control system in industrial applications.

Upgrading the Subsystem for Testing of the Safety Function of a Valve
Němec, Petr ; Fiedler, Petr (referee) ; Arm, Jakub (advisor)
The aim of this work is to develop a theoretical basis for the modernization of the subsystem for testing the valve function, the subsequent design and implementation of the visualization. The thesis briefly describes the steam turbine circulation and bypass technology. Thus, the technology of the system in which the safety function itself is located. Furthermore, the thesis deals with the functional safety analysis and describes the development of three analysis methods FTA, HAZOP and FMEA. The thesis also deals with the analysis and description of an existing application using a state diagram. From the subsequent analysis, the design of a new visualization is realized.
