OPC UA client for communication with PLC B&R Automation
Staněk, Lukáš ; Parák, Roman (referee) ; Lang, Stanislav (advisor)
This thesis is a research of the OPC UA communication protocol with a subsequent example of its implementation in the creating client. The research begins with historical development and then focuses on to the theoretical analysis of OPC UA, these outputs are implemented in the client application OPC UA. This client, which is output of this thessis, then demonstrates the practical use of OPC UA. In this thesis are shown suitable procedures for development of applications, which are generally valid.

Energy meter with PLC communication
Szalbot, Michal ; Mlýnek, Petr (referee) ; Koutný, Martin (advisor)
Our thesis is about development of equipment, which combine two technology. First technology is wattmeter which is used to energy measurement and second is Power line communication. Wattmeter needs two variables for measurement, voltage and current. Voltage measurement is less difficult than measurement of current. Voltage can be reduce and measured by A/D converter. Current has to be transform to voltage and than can be measured same way. To do that we use current transformer. Than we design program for the microcontroller, involvement and PCB. Wattmeter is connect to PLC modem which has been chosen. Fusing this two technology we create wattmeter network. Next step was program which is used to network control and data collecting. This data are used to create charts in web application.

Design of a BPL modem with an ethernet interface
Malček, Ladislav ; Rusz, Martin (referee) ; Musil, Petr (advisor)
The task of the master thesis is the review of selected module PLC Stamp 1200, which provides data communication via power-lines. Subject of the first part is description of PLC communication and its types, especially BPL communication. Afterwards transmission lines, communication interfaces and couplers for injecting the signal into the lines are described. Next, general procedure of design printed circuit boards is presented, followed by specific application rules for prototype BPL modem, especially for RMII and RGMII interfaces. In the second part the design of printed circuit boards for BPL modem is presented. Next, the results of measurement of modem prototype and final device is provided. In the last part of the master thesis, there is a design and results of testing of noise coupler for injection of noise into transmission lines. This device is used for BPL modem testing in worsened conditions.
