Control modernization of two-axis manipulator
Mejzlík, Jiří ; Vetiška, Jan (referee) ; Houška, Pavel (advisor)
The bachelor thesis addresses the modernization of two-axis manipulator that is a part of the galvanizing line. The introductory section describes and evaluates the current situation and specifies the requirements for the device modernization. The selection of the proposed control is based on the analysis of possible solutions which are described in this work. The next part deals with the selection of suitable components and describes the process of implementation.

Model of cleaning station for food processing technology controlled by a control system na PROFIBUS network.
Vyskočil, Jaromír ; Sobotka, Milan (referee) ; Pásek, Jan (advisor)
This bachelor’s thesis deals with design, realization and laboratory commissioning of the model of keg / tank cleaning station (CIP) in foodstuff industry. The model uses two cleaning liquids – water and lye. There are several different types of valves used in the CIP model. They serves for inlet and outlet of lye or water and for separation of the both liquids branches. The control system offers monitoring of pressure, volume flow, level of the lye, etc. The measuring devises mostly communicate with PLC via industrial net PROFIBUS-DP and PA. The same net PROFIBUS-DP also provides communication between PLC and distributed control system Festo (valve island). Configuration and set up of the Festo valve island is described in the thesis as well. Further the work presents processing of the analogue values from different transmitters and their representation in a operator panel. Operator panel (OP) serves for control and visualization of the cleaning station. The OP configuration, the screens structure and the full functionality in the CIP station is explained. The individual screen description is incorporated as well. There are three modes of control – manual, semiautomatic and automatic. Automatic control is based on the recipe concept and the cleaning philosophy is split into several phases. The PLC control is presented in the form of flow diagrams algorithms and the program code in STEP7 is enclosed in attachment on CD ROM.

Extending the Parking and Boxes Laboratory Models for Connectivity to Decentralized Periphery
Mancl, Vlastimil ; Arm, Jakub (referee) ; Jirgl, Miroslav (advisor)
This bachelor’s thesis is about the description and connection of box conveyor and parking lot laboratory models to decentralized periphery made by SIEMENS with the usage of PROFIBUS DP communication standard. In order to do so, programs for controlling models were made in three different programming languages: LAD, STL and GRAPH. The programs were developed in engineering software SIMATIC STEP 7, created especially for programming PLCs made by SIEMENS company. Another part of this thesis is about the visualisation of laboratory models, made in WinCC software. The models were rated in terms of functionality and usability for study purposes. The results of this thesis are programes made for controlling the models with working visualisation and a possibility of connecting these models to decentralized peripheries.

Simple Remote Signalling of PLC Systems
Kacálek, Jan ; Šimek, Václav (referee) ; Tříska, Vít (advisor)
The aim of this thesis is the design and manufacture of hardware and software facilities used for the demonstration of communication with PLC systems. Furthermore, this paper summarizes the possibilities of communication and partially implements the MODBUS protocol via RS485 serial line. The hardware device is fabricated on the PCB and the components commonly available in electronics stores. Includes LCD display and LEDs for status display PLC system. The software application is written in Java and implements the same functionality as the hardware device.
