Model of the lift including AS-Interface network
Žůrek, Martin ; Hynčica, Ondřej (referee) ; Štohl, Radek (advisor)
This bachelor´s thesis occupies with a suggestion of the model of a lift which is driven by a serial industrial bus AS-Interface. In the introduction there is presented theoretical knowledge useful for the reader to the problems especially of the origin and fundamental parametrs of bus AS-Interface, description three levels referential model ISO/OSI which are included in AS-Interface. Further there is the description of transmission of analogical values and standard profiles which are used. In the other part I am trying to solve the model of the lift from the construction standpoint and function of component parts which are included in the lift model. The fourth part devotes to the communications protocol for the control of storeys and the cab box which are shown the data transmission between unit master and unit slave and the opposite. In the last part it is shown programming environment and routines and functions and connection unit slave to unit master. Enclosed are electrotechnical schemes of the model of the lift, the block of programme structure for PLC and technical docummentation of components.

ASI-I modul for lift control boxes
Cseri, Peter ; Fiedler, Petr (referee) ; Štohl, Radek (advisor)
In the first part of my thesis, I was studying materials about AS-Interface network. Then I designed connections between ASI chips and microcontroller that controls the elevator’s control panels. After that I designed all that on double layer board using Eagle layout editor 4.12r2. After that I completed the boards with all electronics circuits and electric components. Then I had to program microcontrollers and microchips for use. These control panels and programs are my final products of this project.

Module of Digital Outputs with Modbus Communication
Vaško, Pavel ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
Goal of mine bachelor’s thesis is create functional module of digital outputs, which can be seen in typical industry using. This module must contain communication interface on protocol Modbus and standard communication bus RS-232, RS-485. The module must be equipped with microcontroller series x51. Size of equipment must be minimalized into the smallest proportion. One part of the thesis is focused on theoretic information about Modbus protocol. Next parts contain charakteristics of communication and software facility.

Control of Curalon cycle batcher
Jílek, Tomáš ; Hynčica, Ondřej (referee) ; Štohl, Radek (advisor)
The work deals with the controlling design of batching machine polyvinyl alcohol fibre, its integration into existing production technologies and the real implementation and verification of the machine functionality for which a design has been made. It also includes a design and implementation operator panel through which can be possible for production line supervising staff to set parameters and monitor the process. Firstly, there is described the default process of dosage, required conditions and restrictions for the newly established dosing machine. In the following part features of newly designed batcher are described, further it deals with the basic parameters and characteristics of selected components, which are important for the execution of its own proceedings. The next part of the work is concerned in detail with the implemented function of controlling algorithm and operator panel, which is provided through interaction with the staff supervising the production line. The last chapter provides the basic configured parameters of the controlled components.

Automation Measurement System
Žampach, Aleš ; Havránek, Zdeněk (referee) ; Štohl, Radek (advisor)
Bachelor’s thesis is bent on creation control software for multimeter and function generator. The first part of the thesis is focused on theoretical problems of individual parts of the whole measuring system and his parts. It show communication control unit with measuring instruments over the GPIB interface. Second part serves to presentation to problems graphical programming method and either as manual to control software for automated measuring system. At last third part are introduced examples of validation measure for check functionality software.

Light wavelength measurement module
Matoušek, Vojtěch ; Štohl, Radek (referee) ; Havránek, Zdeněk (advisor)
Measurement of the wavelength of light source by means of dual-wavelenght photodiode sensor is easy and fast. From the dependencies of the measured voltages corresponding to generated photocurrents of both elements of dual-wavelength sensor it can be calculated the information about wavelenght and intensity of the measured light source. Evaluation, displaying on LCD and sendind of measured information to PC are ensured with microcontroller from the AVR family – ATMega32. One part of the project is also visualization software for PC. Measurement module can be powered with wall socket power adaptor or with battery.

Function block for Simatic, Sinamics devices applied in position applications
Hložek, Vojtěch ; Pásek, Jan (referee) ; Štohl, Radek (advisor)
The objective of this Bachelor's thesis was to make a series of function blocks and functions which would establish a communication between the programmable logic controller (PLC) Siemens S7-300 and the drive system Siemens Sinamics S120 through Profinet or Profibus and datagrams. The function blocks adjust the datagram parameters through which we can control motors connected to a drive system. The functions were made for easy and fast control of the basic motor operations (startup, shutdown, etc.) . The thesis includes a definition of a used software, hardware and the algorithms of the function blocks and functions.

Batch control for model of distillation column
Vobejda, Lukáš ; Kacz, Peter (referee) ; Štohl, Radek (advisor)
This thesis deals with the batch controlling of a distillation column model. The thesis is divided into several parts. The first part, which is more theoretical, summarizes the description of the batch controlling, the distillation process and the equipment used, including the model of the distillation column itself. The second part is focused on the practical implementation. The beginning of this part displays different types of the models produced by the Standard 88. This section is followed by a description of a device database in the environment of FactoryTalk Batch Equipment Editor, creation of a logical phase codes using functions of the PhaseManager in the environment of RSLogix5000 and a creation of a recipe in the environment of FactoryTalk Batch Recipe Editor. The last part of this thesis deals with the visualization created in the FactoryTalk View Studio SE and final testing of the entire process.
