Conversion of WinCC screens to manufacturing system COMES
Kárník, Jiří ; Štohl, Radek (referee) ; Pásek, Jan (advisor)
Presented thesis describes visualization of industrial processes. It focuses especially on the conversion of visualized data between Siemens Simatic WinCC and XML format. Build-in script editor is used to do aforementioned operations. Conversion and implementation of the data to the MES system COMES is solved in the next section of the thesis. Thesis also contains analysis of both used industrial systems and solves graphic format selection, which will be used to display image data in system COMES

Demonstration task - Motor protection with MODBUS TCP
Berčík, Dominik ; Drahota, Petr (referee) ; Štohl, Radek (advisor)
The purpose of this bachelor work is to design and implement the demostration panel for laboratory task in which asynchronous motor failures will be simulated. These will be evaluated using the intelligent electronic device REF615, which communicates via ModBus/TCP, and compared with the values of the motor protection E1 plus 193-EECB and the Power Flex 525 AC. Both devices communicate by Ethernet/IP. A part of the work is an analysis of functionality of used components including their configuration and description of communication protocols ModBus/TCP and Ethernet/IP.

House alarm - hardware
Vlach, Jiří ; Štohl, Radek (referee) ; Fiedler, Petr (advisor)
This work deals with the design and realization of a modular security central unit's hardware positioned in familial houses. As an operating component of the central unit is used Module Rabbit 3365 with an integrated Ethernet interface. Based on user's requirements and general requirements for electronic security system, circuit diagrams of the central unit's motherboard and power supply with a function of backup power supply are designed. The work also includes layout of a keyboard and LCD display. Printed circuit boards are designed, produced and assembled. The device is set to work. The last part concerns programming of the module Rabbit 3365 in Dynamic C. Gradually, set of operating functions for individual components of the security central unit are implemented.

Control of pneumatic press model
Sikora, Martin ; Stibor, Karel (referee) ; Štohl, Radek (advisor)
This thesis deals with improving of the pneumatic press model. The document contains short description of press model. It also focuses on completion of safety and functionality of the machine. There are an analyse and an aplication of instruments in the chapter Choice of instrumentation for change of the pressure force and for the increase of safety of this machine. The chapter Construction of the press model selects the mechanical components and solves the aplication for press model. In the section Extension of the control program there are the analyses of the control algorithms and programs for the safety PLC and PLC for vizualization. The last part of this work is devoted to vizualization, which displays the states of the sensors and safety PLC. In vizualization there is the setting of hand-operated mode or the automatic control mode with different pressing force changing in time.

Flow Measurement of Hot Dusty Gas
Dostál, Jiří ; Štohl, Radek (referee) ; Šedivá, Soňa (advisor)
The bachelor thesis deals with the measurement of hot dusty gas. The introduction outlines the problems of measurement. Another part of the work contains a theoretical introduction to the measurement of gas flow. In successive chapters the basic principles and characteristics of suitable methods for measuring the hot dusty gases are described. Finally, the function blocks are implemented in the Simatic STEP7 for calculation of volume flow rate for the methods selected in the theoretical part and visualization in WinCC flexible.
