Slave EtherCAT module
Hadámek, Jakub ; Bradáč, Zdeněk (referee) ; Valach, Soběslav (advisor)
The aim of this thesis is to create slave device using an EtherCAT fieldbus. It is focused on introduction of protocol and it’s implementation on microcontroller XMC4800 from Infineon. The result is a functional slave module with digital inputs and outputs controlled by EtherCAT master. In addition, the firmware of the microcontroller can be updated over the network. It also describes jitter measurements and comparison with faster Gigabit Ethernet.

Control module of stepper motor for positional system with Ethernet
Raszka, Dan ; Kubíček, Michal (referee) ; Kolka, Zdeněk (advisor)
This paper describes the design of Stepper motor controller module controlled over Ethernet for positioning system. Part of this work describes analysis of the assignment, design of modular circuit, choosing right components and prototype design of communication and power module. In another part each module is described with emphasis to modularity. It deals with description of manufactured prototypes and their tested paramethers.

Control of the laboratory model of synchronous drives
Koubík, Martin ; Bílek, Michal (referee) ; Zezulka, František (advisor)
The aim of this theses describes the design of the control program for the synchronous axes model and reconstruction of this model. The first main part is description of synchronous axes model, description of engines and other components of model. Then model modifications are described. Another part is discussing the TwinCAT programming environment and describe all important elements that must be performed for proper functionality of the model. There is also a description of function blocks that are used to program motion sequences. The last part is described of demonstration program and program which would be used for teaching.

Automobile Mirror Testing
Kováč, Ondrej ; Kofroň, Jan (advisor) ; Malohlava, Michal (referee)
In many sectors of the industry, the testing is a part of the production process. It prevents defective goods to appear on the market. Manually assemble automobile mirrors are tested to meet the minimal requirements of the producer and to reject badly mounted pieces. We decided to automate this process in order speed up and ensure the reliability of the testing. A special hardware was designed for this purpose. It is completely controlled by our application running on a regular PC. One of the improvements we have accomplished is a noticeable acceleration of the testing achieved by the parallel test execution. Development of this project contributes to the creation of a library for controlling industrial hardware.

Control and synchronization of electric drives in NI LabVIEW
Martini, Silvano ; Šubrt, Kamil (referee) ; Houška, Pavel (advisor)
This thesis in his beginning describes basics of motor controlling and function principles of EtherCAT bus. Majority of the thesis is devoted to extending module SoftMotion for development environment NI LabVIEW. There is described the basic concept of the module, ways of functions using, various programming approaches and examples. Realization of hardware control is mentioned at the end.

Using the EtherCAT bus couplers in the development environment NI LabVIEW
Svoboda, Filip ; Šubrt, Kamil (referee) ; Houška, Pavel (advisor)
This thesis focuses on EtherCAT fieldbus and its application by using NI LabVIEW. There are described the theoretical part of network elements designed for automation use in first part. Next part includes description of the EtherCAT and its advantages. There is described how NI LabVIEW accesses to this fieldbus in the next part. The real application developing process on the specific manipulator is treated then. It is controlled by the bus coupler. The results of the experiment are discussed in the last chapter.

Software interface for operating AFE-DK via EtherCat
Kokeš, Petr
Software interface for operating the AFE-DK embedded program via EtherCat is defined. AFE-DK is the implementation of PWM rectifier control algorithms into EMADYN-D controller, which is a "Slave" device for the EtherCat network communication. Transferred data structures, the Slave and EtherCat state machines as well as the Slave events are described.
