Control of concrete mixcure technology
Kurimai, Igor ; Mádl,, Pavel (referee) ; Zezulka, František (advisor)
Thesis presents control of concrete mixcure technology Prefa Brno – production plant Strážnice. It deals with areas of process control system using the control system Siemens S7 – 300. The first part of thesis describes concrete mixcure technology and control system SIMATIC S7 – 300. Algorithms, used for control of concrete mixcure technology, are designed in the next part of thesis. Further it is discussed control program and connection to the system SCADA. Time frame of process is described in the finally. There are defined critical processes, which can occur in the control. In the next the thesis deals with hardware performance for different types of concrete mixcure technology. The results of introduction control system into industrial process are analysed at the end.

Industrial Signal Processing and Visulalization Using PLC Systems
Hauer, Petr ; Hubík,, Vladimír (referee) ; Šebesta, Jiří (advisor)
This master’s thesis aims to familiarize with the types of signals used in industrial automation technology. Below are the methods for their processing and transfering to the PLC control system It is described method of processing these signals using an industrial controller of the S7 - 300 and a program for creating visualizations SIMATIC WinCC V7.0. The second part of the master’s thesis deals with the implementation of the control software of a specific technological process.

Innovation of "Parking" Laboratory Models
Pindel, Tomáš ; Benešl, Tomáš (referee) ; Jirgl, Miroslav (advisor)
This bachelor thesis deals with models of a parking lot used in the BPGA course as a learning kit,its innovation,realization of a universal connection to all sorts of the PLC SIMATIC S7-1500 in the laboratory and programming of model tasks in four programming languages: LAD, STL, GRAPH and SCL. The differences in programming in each of the languages are also analysed. Further on the making of a visualisation in WinCC is described for these model tasks. The result of this bachelor thesis are two fully-functionial models that can be used for teaching students with a connection to the PLC S7-1500 and their respective documentation. Finally, the model task and its corresponding program in languages LAD, STL, GRAPH and SCL is included + the created visualisation for HMI and PC.

PLC controlled system for manipulated arm
Slavík, Miroslav ; Zemánek, Pavel (referee) ; Pásek, Jan (advisor)
In this bachelor´s thesis is solved automatic task of PLC controled manipulated arm. For this controled is used Siemens Simatic 200 with programing enviroment MicroWin. The servos are moving with parts of arm. The servos are conected to the PLC trought PCB of electronics interface. PCB is created specially for this aim. Design of PCB is described. Details description is PLC´s program. Comunication between PLC and SCADA is trought a PPI cable. Vizualition of proces is runing on the ControlWeb by Moravians instrument, this is descripted also. To the Manipulated arm is instaled conveyor. Boxes are transporting by conveyor. Pyramid is build from boxes.

Communication Server Design and Implementation
Sedláček, Robert ; Kenyeres, Martin (referee) ; Škorpil, Vladislav (advisor)
In the first part of this work, there is analysis of the industrial proprietary protocol S7 by Siemens. The analysis is performed by Wireshark between the programmable controller S7-1200 and Simatic NET OPC server. This protocol is based on other protocols whose proposals and solutions are completely or at least partially described in this work. On the basis of this information is created a communication library in C ++, which allows the transmission of variables. This library is subsequently used in the implementation of the communication server through which one can easily access variables in the programmable machine with a text protocol.

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.

Control system of brewhouse
Šulc, Martin ; Kaczmarczyk, Václav (referee) ; Zezulka, František (advisor)
Investigation of the necessary theory of the brewing industry. Based on the findings to propose the optimal action and measuring elements such as temperature, pressure, pneumatic valves, drives and others. Subsequent characterization of all elements from the perspective of the control system and extension of technological scheme of measuring and regulating signs. For the section of the brewery brewhouse writing technological sequence with specifying the steps. Based on this description, create a control program for Simatic S7-300 from Siemens. The program is written in STL which takes the form of structured text. Visualization and process control is provided by SCADA system TomPack from the company ProjectSoft. The system communicates with the PLC via DDE server.

Control of manufacturing line
Stříž, Martin ; Hynčica, Ondřej (referee) ; Zezulka, František (advisor)
The main task of this project was to design a program for control system of dry concrete product handling line. This manufacturing line is controlled by a programmable logical controller Simatic S7 300 produced by Siemens company. A graphical touch panel TP 177A and a control desk with buttons are used as human machine interface. The developed program contains functions for control conveyors, manipulator and cleaning station. Management of formulations stored in PLC by operator is also included in program. The theoretical part deals with dimensioning of drives for two mechanical systems of this manufacturing line. Choice of power output of the electric motors depends on required torque. A fundamental principles and rules of five basic programming languages for PLC in accordance with standard IEC 61131-3 are specified here. The practical part describes project creation in Step 7 software and functions and capabilities of projected system by means of user manual.
