Modbus TCP interface
Krotký, Pavel ; Bohrn, Marek (referee) ; Pavlík, Michal (advisor)
Main puropose of this thesis is to design and develop Ethernet to serial interface converter. Ethernet and serial line protocols are briefly described. Appropriate microprocessor and hardware for realisation of each physical layars were choosen. Convertor uses Texas Instrument's TI-RTOS operating system. Convertor's purpose is to pass on communication between physical layers and also fulfill webserver role with configuration possibilities.

Terminal for testing of data communication of public transport vehicles
Fiala, Michal ; Holek, Radovan (referee) ; Macho, Tomáš (advisor)
This term paper deals with subject of wireless communication of city rail transport cars. In this paper are described individual modules for transmission and receiving of data containing communication between city rail transport cars and measures of siding switches. Then there are discussed possibilities of design of system for testing functionality of transmitting and receiving modules and the system is consequently designed. There are also described communication principles and protocol used for wireless communication and MODBUS protocol used for communication over RS-485 serial line. In the end was the system manufactured, completed and equipped with necessary software.

Graphical LCD display
Kulka, Branislav ; Kaczmarczyk, Václav (referee) ; Bradáč, Zdeněk (advisor)
Bachelor's thesis "Graphical LCD Display" is focused on designing graphical diplaying unit for displaying industrial data, which is equipped with RS232/RS485 interface and digital inputs and outputs. Device is equipped with I51 series microcontroller. In this work MODBUS protocol is discussed and implemented. Data can be dispayed on circle scale or in form of bargraph indicators.

Module of Digital Outputs with Modbus Communication
Vaško, Pavel ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
Goal of mine bachelor’s thesis is create functional module of digital outputs, which can be seen in typical industry using. This module must contain communication interface on protocol Modbus and standard communication bus RS-232, RS-485. The module must be equipped with microcontroller series x51. Size of equipment must be minimalized into the smallest proportion. One part of the thesis is focused on theoretic information about Modbus protocol. Next parts contain charakteristics of communication and software facility.

Transfer the IEC 61850 standard for communication protocol ModBus
Šikula, Jiří ; ABB, Oleksiy Melnyk, (referee) ; Polsterová, Helena (advisor)
This work describes the modbus communication protocol used in earlier and recent medium voltage switchgears. It also describes the IEC61850, a communication standard for most of the switchgear manufacturers as ABB, Siemens and others. It further describes the station automation gateway COM600, which is capable of conversion between many communication protocols. And finaly in this work you can find the concept of a device which is capable of conversion from IEC61850 to Modbus.

Simulator and client for MODBUS devices
Ondrášek, Michael ; Franek, Lešek (referee) ; Fiedler, Petr (advisor)
This bachelor’s thesis deals with communication protocol MODBUS. The properties of the protocol and its function are described at the beginning of a thesis. There are designed two applications on the basis of identified properties in the other part of thesis, they represent the server part and the client´s part. The server part is implemented by selected functions of protocol and it represents devices for data collection. The next part is the detailed design of applications and the description of their realization. The last part deals with testing of designed applications with available SW simulators. The thesis deals also with user manual for control of created applications.
