Safety of pneumatic press model
Nešpor, Tomáš ; Foukal, Roman (referee) ; Štohl, Radek (advisor)
This thesis is concerning functional safety of machinery, concretely safeguard of model of pneumatic press. In the document is briefly introduced norm, which determines safety standards during designing of safe machine. In the next part is mentioned risk assessment written as technical report. In risk assessment are identified possible risks that could appear during working on machine. Furthermore there are listed safety precautions ensuing from assessed risks, list of elements which has been used to safety control of pneumatic press and evaluation of risks according to EN ISO 13849-1 norm. In the part Programming of the device (Programování zařízení) is configuration manual of the device and description of control programme. The description of visualization in FactoryTalk programme is at the end of this thesis.

Automation of software control systems
Sysel, Radek ; Pásek, Jan (referee) ; Štohl, Radek (advisor)
The diploma thesis is about the design process of complex objects in automation and their rapid inclusion in the entire process technology. It shows the proces of creating a database model to generate into the SCADA application. The aim of the thesis is to show what all is needed to create, to produce a functional visualization model connected to the control system PLC. There is the analysis of the automated system change management, when it is processing technologies developed and we must do it based on customer feedback and revisions add new objects.

Control of three axis of manipulator
Matějíček, Miroslav ; Hynčica, Ondřej (referee) ; Štohl, Radek (advisor)
Bachelor thesis deals with controlling of free axes of manipulator model by the help of servo – actuator with the help of instrumentation from the company Allen Bradley. It is used PLC from the series ControlLogix, which controls servo – actuators with the help of interface SERCOS and the control part Kinetix 2000. The procedure of the configuration of axes and configuration of coordinated system and a method of programming of the governing of axes including an exemplary laboratory work are given in the thesis.

Controller of hot runner for injection molds
Chrenka, Eduard ; Fiedler, Petr (referee) ; Štohl, Radek (advisor)
The thesis focuses on implementation of a hot runner controller for injection molds for plastic materials with a maximum number of 56 regulated zones. The first part of the thesis deals with already existing and used solutions of the given subject. The following part of the thesis describes the principles of temperature measurement by means of thermoelectric sensors, including their linearization as well as communication protocols MODBUS, EUROMAP 17. The identification of a regulated system ( heating zone) has been carried out before the hardware design. The development process is divided into some parts : system conception, hardware design, software development. The controller consists of measuring modules designed to collect data and handle power controllers for management of performance of heating elements. The necessary calculation power is integrated into the controllling computer. All parts of a hot runner controller are implemented taking into account the costs.

Crossroad model with industrial communication
Záviš, Jan ; Macho, Tomáš (referee) ; Štohl, Radek (advisor)
This diploma project summarizes a theoretical introduction regarding the issue of traffic light control. Further there is industrial communication discussed, where they are the Ethernet / IP protocol and the Modbus TCP protocol described more in detail. The following is the description of the Logix series programmable controllers. Then the diploma follows up with market research in order to find the most suitable development kit which is used as a trial prototype. Then it is concerned with a development kit with a communication module from AND-TECH company. Software was developed on them, more specifically a library for processor ports, memory and the Modbus TCP protocol. After verifying the functionality of the software, the hardware design was started. From the first site it is development kit and module and from the second site there are input and output circuits. There must be the assessment of the results found during the test operation. The end of the document describes incorrect steps that were repaired in hardware.

Risk assessment of the barman machine powered by Magnemotion
Jirků, Lukáš ; Stibor, Karel (referee) ; Štohl, Radek (advisor)
This thesis deals with the risk assessment of machinery, specifically the automated bartender model. The thesis includes the replacement of a pneumatic feeder with an electric linear conveyor using MagneMotion technology. The theoretical part of the thesis describes the automated bartender model, MagneMotion independent trolley technology and GuardLink safety technology. This is followed by the development of a risk assessment on the machinery according to ČSN EN ISO 12 100. The next part of the thesis describes the design and implementation of conveyor replacement and safety measures to reduce the risks resulting from the risk assessment. Finally, the implemented safety measures are verified.

Distillation column model control via Modbus TCP
Kozovský, Matúš ; Kaczmarczyk, Václav (referee) ; Štohl, Radek (advisor)
The aim of the work is the introduction of the basic technologies of web servers and the subsequent design and implementation of applications designed for web-server which will be used for communication with the distillation column model to create a simple and intuitive user interface for monitoring the state of the model and possible management model. This application will also use SQL server to backup the production process and message logging.
