Monitoring system for gasification of wood chips
Vaško, Radim ; Bradáč, Zdeněk (referee) ; Štohl, Radek (advisor)
In my work, I am developing measuring application for monitoring gas quality. I explain the technological process of measurement by spectrometric sensors. I design an industrial cabinet with PLC. I’m explaining algorithms of program for PLC AMiT AMiNi4DS. I describe inner communication of system. I assemble device mechanically and electrically. I am then setting the system ready for use. I create SCADA project for application. I describe the general characteristic of SCADA systems and specific SCADA software Reliance 4.

Medium voltage substation automation using control system COM600 and standard IEC61850
Havelka, Tomáš ; Štaffa, Jan (referee) ; Háze, Jiří (advisor)
This work deals with problematic of standard IEC61850, mainly with chapter IEC 61850-9-2 LE which is commonly known as Process bus communication. There are described advanced tools of the control system COM600 with detail description of their configuration in this work. It also deals with configuration of IEC 61850-9-2 LE with Relion family protection relays and its implementation to the control system COM600. The main aim of this work is focused on configuration of IEC 61850-9-2 standard with protection relays, configuration and detail description of COM600 advanced tools, description of Logic processor, further custom design and appliaction configuration global reset of Logic procesor in control system COM600.

CIP industrial protocol simulation
Molent, Michal ; Musil, Petr (referee) ; Blažek, Petr (advisor)
The thesis is about industrial automatic CIP protocol, which belongs to SCADA systems. The first part is focused on basic principles of CIP protocol and on analysis of two protocols (EtherNET/IP and DeviceNet), which are based on CIP protocol. The second part deals with designing scenarios for a simulation. The simulation of one-way communication, two-way communication with help of reads from the console and two-way real time communication between Raspberries PI 3B+. The third part deals with a realization of the simulation, a start-up and a function of predefined scenarios and graphic interface. The fourth part deals with analysis network communication in situations, which occur during a protocol EtherNet/IP simulation.

A Library for Detection of Semantic Properties of Tree Structures
Panov, Sergey ; Rogalewicz, Adam (referee) ; Smrčka, Aleš (advisor)
Testování multikomponentních IT a IoT systémů, které zpracovávají proudy různých zpráv je složitou úlohou. Proč je to složité? Kvůli množství komponentů, jejích asynchronní interakcí, různým kombinacím události pro testování, testovacímu prostředí, které se liší od reálného a množství dalším důvodů. Táhle práce navrhuje způsob generování komplexních dat pro testovací účely s minimálním zásahem vývojářů. Generování dat založeno na analýze sledu komunikace reálného systému a následnou syntézou podobných sledů pro testování. Práce také navrhuje framework na prvotní analýzu zpráv přenášených v zachycené komunikace. Tohle může být uděláno použitím různých abstraktních modelů: modelu zprávy a modelu komunikaci. Výsledkem téhle práce je implementovaní knihovna na tvorbu modelu zprávy a množina operací pro práci s tímto modelem.

Management of the energy transmission system polygon
Bohačík, Antonín ; Musil, Petr (referee) ; Blažek, Petr (advisor)
The diploma thesis is focused on the creation of a control interface for a polygon simulating the electrical distribution network of the Czech Republic, where communication between substations is realized by IEC 60870-5-104 protocol. The theoretical part of the thesis explains the basic principles, properties and possibilities of communication standards IEC 60870 and IEC 61850. The next part is focused on the actual implementation and subsequent implementation of the control interface, including the implementation of the IEC 61850-80-1 module for data transfer between the mentioned standards. The last part describes the created behavior scenarios or the analysis of communication itself.

PLC SCADA System for Control of Wind Tunnel
Trenčan, Tomáš ; Jirgl, Miroslav (referee) ; Arm, Jakub (advisor)
This work focuses on programmable logic controllers (PLC) made by WAGO and SCADA systems. It consists of two parts, theoretical part and a practical part. In theoretical part there are terms which explains SCADA systems, WAGO PLC and programming software e!COCKPIT made by WAGO and searches of free SCADA systems supporting communication through Modbus TCP. One of the SCADA systems was chosen as a visualization software for two task in practical part. Practical part consists of PLC codes made in programming software e!COCKPIT for two tasks, wind tunnel and controlled axis and their visualization.

Appropriate strategy for security incident detection in industrial networks
Kuchař, Karel ; Blažek, Petr (referee) ; Fujdiak, Radek (advisor)
This diploma thesis is focused on problematics of the industrial networks and offered security by the industrial protocols. The goal of this thesis is to create specific methods for detection of security incidents. This thesis is mainly focused on protocols Modbus/TCP and DNP3. In the theoretical part, the industrial protocols are described, there are defined vectors of attacks and is described security of each protocol. The practical part is focused on the description and simulation of security incidents. Based on the data gathered from the simulations, there are identified threats by the introduced detection methods. These methods are using for detecting the security incident an abnormality in the network traffic by created formulas or machine learning. Designed methods are implemented to IDS (Intrusion Detection System) of the system Zeek. With the designed methods, it is possible to detect selected security incidents in the destination workstation.
