Foundation Fieldbus peripheries
Ferjančič, Michal ; Fiedler, Petr (referee) ; Štohl, Radek (advisor)
Master’s thesis deals be occupied with the transmission of process data with peripheries to control devices. Data transmission with performs through two types of industrial networks. Use with these two Foundation Fieldbus and EtherNet / IP. In work is shows method conversion through gateway between the two networks. Here there is adduced method to connected and configure devices on the networks and also their implementation. Part of this work is also creating a visualization of these peripherals and the gateway. The work is also presents possible use for laboratory task to practice.

Sensor devices emulator for industrial networks
Malček, Ladislav ; Fujdiak, Radek (referee) ; Blažek, Petr (advisor)
The task of bachelor thesis is design of sensor devices emulator for industrial networks. Subject of the first part is description, safety and control of electric network. Afterwards the current and voltage sensors and merging units for analysis of data are presented, followed by description of the used microcontroller, and all the individual components of simulator. In the next part the design of circuits for voltage, current and binary outputs is presented. The third part of thesis are designs of control terminal and web interface for setting of simulated values by user. After physical realization of emulator, it was tested on a control device. The last part of the thesis are results of testing.

Connection between PC and PLC through Ethernet Powerlink
Špaček, Marek ; Chomát, Luděk (referee) ; Malounek, Petr (advisor)
The aim of my bachelor‘s thesis is connection between PC and PLC with industrial network Ethernet Powerlink. This work describes the basic principle of Powerlink network connection and the option of connecting ordinary PC to Powerlink network according to Powerlink standard. This allows you to use your computer for setting parameters and visualization of other devices connected to the Powerlink network. The result of this work is an application that after the connection to the EPL network detects all active devices on the network, shows their names and eventually displays their variables.

Experimental work with POF - Polymer optical fibers
Doležal, Ondřej ; Urban, František (referee) ; Filka, Miloslav (advisor)
In this diploma thesis, the reader is familiarized with polymer optical fiber (POF). Firstly is mentioned theoretical background of optical fibers and optical transmission. The following are the basic properties and significant parameters of POF, a more detailed description of each type POF and their essential advantages and disadvantages in comparison with established optical fibers based on glass. The next chapter describes the area of practical issues: working with fibers and fiber installation, as well as the available connectors and methods of measurement of POF. Closely are analyzed knowledge of the practice, including the utilize in the aerospace and automotive industries, as well as in industrial networks, access data networks and local area networks. The practical part includes the measurement of basic transmission and mechanical parameters, including analysis of the results. The conclusion summarizes all the findings and results of this work, including possible future developments.

Possibilities of increasing the throughput of optical fiber industrial networks
Čičmanský, Tomáš ; Münster, Petr (referee) ; Filka, Miloslav (advisor)
Diploma thesis deals with problems of industrial networks using optical fiber as the main transmission lines. The task of the diploma work is to study and summarize the issues of industrial networks as well as the ways to increase their transmission capacity. In telecommunications and computer networks are generally used multiplexes, thanks to which we are able to achieve the desired transmission capacity. Consequently, the following work deals with the selection of the adequate solutions using described multiplexes as well as other transmission methods. The aim of the diploma work is to compare various renovation techniques of an old industrial network. Using this network as an example the work should demonstrate the individual problems and their solutions while considering different types of methods used. Based on the price, the performance and the difficulty to install other devices and transmission media we are able to select the appropriate solution for optical link.

Design of supply network configuration for large engineering company
Němec, Jan ; Holoubek, Jiří (referee) ; Topolánek, David (advisor)
This master-thesis analyzes issues of suggestion configuration of power supply network of industrial business. The option of the scheme of the configuration, the voltage level, the way of compensation of the reactive power, the way of the suppretion of the energetic interference and other requirements is included in the main tasks. This option has to be convenient with the requirements of the industrial business. The important point of this proposal is to prevent the influence of the superordinate distribution network. The compensation which keeps the power factor in the prescribed limits is one of the precautions against the influencing of the network. The second precaution is the elimination of energetic interference. The higher voltage, the fluctuation and the asymmetry of the voltage are the interferences which have the biggest impact on the industrial networks. The master-thesis offers the summary of the possibilities and ways of the elimination of the basic elements of the energetic interference.

Industrial device authentication system using blockchain
Hnátek, Michal ; Holasová, Eva (referee) ; Fujdiak, Radek (advisor)
This bachelor thesis deals primarily with industrial networks and blockchain. Current implementations of network security are enumerated. A large part is devoted to the analysis of consensus algorithms and their suitability for industrial networks. The work also includes an extensive comparison of libraries for blockchain creation. In the area of industrial networks, the Modbus protocol is represented. The general function of blockchain and its modifications for use in industrial private networks are described. The creation of a private blockchain with the Proof of Authority consensus algorithm using the go-ethereum library is described, as well as the creation of a smart contract for a given blockchain.
