Modernization of the I/O simulator for PLC
Veselý, Petr ; Jirgl, Miroslav (referee) ; Štohl, Radek (advisor)
This thesis deals with the reconstruction of an I/O simulator for PLC. The content of the first chapter is an introduction to the PLC and a description of the standardization of discrete and analog signals. Subsequently, the physical simulator located in the laboratory is described. The next part of this thesis is devoted to the design of the modification of the analog inputs and outputs in order to communicate properly with the modules. Further, the modification of the analog outputs on the simulator and also the modification of the cables between the PLC and the simulator are presented. In the fifth chapter I describe the Add Profile technology and then present the solution of the demonstration and test problem. Finally, I describe the verification of the functionality of all simulators.

CANopen drive PLC control
Hámor, Martin ; Knobloch, Jan (referee) ; Ctibor, Jiří (advisor)
The main goal of this bachelor’s thesis was to create an electric drive controlled by a PLC using the CANopen protocol. Three methods of message transmission were tested using Schneider Electric Machine Expert Logic Builder software, designed for PLC programming, and PCAN-View, which monitored incoming and outcoming messages in real time. Control methods are detailed in chapter 6, one of these methods was successful.

Development of water show control
Havran, Lukáš ; Pruša, Radomír (referee) ; Štěpánek, Vojtěch (advisor)
This thesis deals with the design methodology for controlling a digital water curtain. The research section focuses on analyzing control systems suitable for this technology and on software tools that enable the implementation of a user application designed to control the water curtain. Based on the research, the practical part involves the implementation of a user application for composing and executing water scenes. Another aspect of the practical part is the selection and programming of control hardware that manages the water jets. The control principle relies on communication between the user application and the control hardware. The practical part is further complemented by the construction design of the digital water curtain in the form of a 3D model, which includes all construction elements, including the control hardware.

Virtual commissioning of a robotic learning system
Dejmek, Tomáš ; Knoflíček, Radek (referee) ; Vetiška, Jan (advisor)
This bachelor thesis deals with the virtual commissioning of a robotic system. This system is located in the premises of the Institute of Production Machines, Systems and Robotics of Brno University of Technology. Virtual commissioning has become an indispensable component in the creation of automated workplaces in recent years. It has an impact on reducing costs and downtime in production. The thesis contains a theoretical part, which is devoted to the research of topics related to virtual commissioning. This is put into a broader context with the concept of Industry 4.0. This is followed by a description of the parts of the robotic system and a description of the operations to be performed by the system. The practical part is devoted to a description of the creation of a simulation model in the RobotStudio software. This is followed by the last part, which introduces the creation of educational materials. These materials are text files containing a detailed procedure for working with RobotStudio. The output of this work is the virtual commissioning and creation of the tutorial materials.

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.

An Innovative Control System for Water Supply Management at a Farm
Doležal, Aleš ; Sýkora, Tomáš (referee) ; Jirgl, Miroslav (advisor)
The thesis deals with the implementation of an innovative control system for the management and supply of water to the farm. For the innovation, fiber optic communication between the main switchboard and the poles at the wells was chosen. Furthermore, the thesis deals with the selection of components and sensors for the implementation of the system. The program that controls the whole application is written in ladder language in a development environment from Unitronics, from which the control PLC is also supplied.

Identification of industrial devices
Šotola, Bohuslav ; Blažek, Petr (referee) ; Pospíšil, Ondřej (advisor)
This thesis, titled Identification of Industrial Devices, deals with the use of machine learning for the passive identification of exclusively programmable logic controllers (PLCs) from Siemens, communicating via network traffic. The identification is performed to obtain information about vulnerabilities in the devices currently in use. The motivation for introducing identification in the industry is to minimize the likelihood of attacks and thus reduce losses in production. Datasets in the field of Industrial Control Systems (ICS) are created for targeted device identification within 5 minutes of capturing network traffic. These datasets are statistically processed to find input parameters showing independence from topology and time. The statistically processed parameters are then subjected to machine learning models. If they are found to be sufficiently independent, the idea is verified on independent data not related to previous ones. In identification, there is also an attempt to utilize network transmission parameters that are independent of the PLC device manufacturer. Identification of PLC devices is possible, with the ideal use of the older version of the proprietary S7 protocol, as it allows identification within 5 minutes of capturing traffic. Identification based on the older version of the protocol is also relevant because it is used in practice. An obstacle to capturing traffic for identification is the fact that potential users often need appropriate permissions. Firmware updates must be taken into account, providing new data security features.
