Collaborative robot control by PLC
Novotný, Jiří ; Benešl, Tomáš (referee) ; Macho, Tomáš (advisor)
This bachelor thesis deals with the control of a collaborative robot using a PLC. To implement this work is used collaborative robot YuMi from ABB and PLC from Siemens of latest series S7-1500. We will get acquainted with products which have been used in project and with the development environment for PLC (TIA Portal) and for robot (RobotStudio). We define the requirements for the communication interface between the robot and the PLC. We will describe a demonstrating task requiring control of a robot using a PLC. The task demonstrates a real application for the end user. Then we implement PROFINET communication interface and implement the described task for the robot. The final solution is then tested in real production line.

Milling machine CNC control
Krejčí, Jan ; Benešl, Tomáš (referee) ; Bradáč, Zdeněk (advisor)
This diploma thesis deals with rebuild of manual drill-mill machine BF20L into CNC mill machine, 3D model of that and eventual control using PLC. All axes are powered by stepper motors, with encoders, connected to control cards and industrial computer from company Beckhoff. For this control is made full switchboard, supplemented by electrical wiring diagram. Program control along with visualization is made in software TwinCAT 3. Drill-mill machine can be controlled manually or automatically by program.

Software Framework for PLC Program Standardization
Hrubý, Otto ; Benešl, Tomáš (referee) ; Jirgl, Miroslav (advisor)
This thesis deals with standardization of PLC software used in company. The aim of this thesis was to design program for single-purpose machine used in assembly process and communication program to allow machines to be used in Master-Slave system as Slave. The programs use elements from IEC 61131-3 to make them portable among different integrated development environments. The software was designed to be easily reusable and modifiable for different machines.

Simulator of current output 0-24mA
Mačišáková, Kateřina ; Benešl, Tomáš (referee) ; Bradáč, Zdeněk (advisor)
This bachelor thesis deals with design of very accurate current output simulator 0-24 mA with microcontroller with resolution 0.001 mA. In the thesis I deal with the market re-search with similar devices, theory and then with the conception of the whole system concept, with the identification of used components and with the evaluation of their suitability. I propose here a circuit diagram and a printed circuit board, which I then produce and install. For the resulting device I design and produce a box that will suita-bly complement and unify the entire system. I will revive the whole device, program it and test its functionality.

Safety analysis and safety measures for Industry 4.0 testbed
Kroulík, Matěj ; Benešl, Tomáš (referee) ; Fiedler, Petr (advisor)
This thesis deals with the requirements of security of machinery with respect to valid security standards. Especially it focusses on standards EN ISO 12100 and EN ISO 13849-1. Further the paper contains overview of security elements of machinery used in industry, also introduce the conception of Industry 4.0 testbed. In the last section, the theoretical findings are used to analyze and evaluate risks and theoretical proposal of security on Industry 4.0 testbed.

Functional model of a small hydro power plant control unit
Rusnák, František ; Arm, Jakub (referee) ; Benešl, Tomáš (advisor)
This semester work deals with realization of functional model of control unit for hydroelectric power station. Main task of this work is realization rectifier with active power factor correction, which is used instead of commonly used frequency converter. Control unit is designed for asynchronous motor in generator operation with self-excitation. The propeller turbine is used as propulsion. Theoretical part includes theory of the PFC converters. Practical part includes calculations for components of PFC converter and assembly of DPS PFC converter.

Application for Industrial Robot Demonstration
Lázničková, Jana ; Benešl, Tomáš (referee) ; Jirgl, Miroslav (advisor)
The aim of this paper is to create a demo application that presents the interaction of the Mitsubishi RV-4FR industrial robot with the SICK Inspector industrial camera. The robot step by step takes out items from the input stock (items can be randomly sorted), uses the camera to identify a specific item. Items that are not in order are placed in the storage stock. Conversely, the items in the corresponding order are folded into two output stocks and creating two different images.

SCARA control system
Bittner, Jakub ; Burian, František (referee) ; Benešl, Tomáš (advisor)
This thesis shows the process of restoring a SCARA type robot, which has had its controller destroyed. The signal cables as well as the power ones were rewired so that it would be able to create new control system for robot arm. New control system is created using devices from Beckhoff company. For that identification of motors is required. After that PC control is programmend to control every single axis of manipulator, with this program vizualizations of controll elements are created. In the end linear interpolation of movement between points is implemented.
