In this thesis is proposed implementation of weather station with web server built on hardware platform with microcontroller STM32f417 and ethernet interface.

This master’s thesis deals with the renewal of electrical equipment of 2D manipulator and putting it into operation. It contains a description of the machine, used components and their connections. It describes the principle of two communication buses, which are used for machine control. Next part is devoted to the safety analysis of the machine. Following chapters describe developing of a control program and designing of a visualization.

The main objective of this thesis is to create a monitoring system for an asynchronous motor using IED REF615. For REF615 devices it is necessary to make the appropriate configuration and connection.The device communicate with the MVI69-MNET card by Modbus/TCP protocol. The thesis describes the operation of an asynchronous motor through the use of a PowerFlex 40 frequency changer. PowerFlex 40 sends data via an Ethernet/IP connection. The thesis also describes a program in PLC for monitoring the power status of an asynchronous motor. The next part of my work is a visualization created in the FactoryTalk View Studio. In conclusion, the thesis is tested by connecting all of the components as well as all of the proposed functions.

This master thesis deals with the possibilities of simulation and optimalization of ethernet networks in Matlab interface. Ethernet technology, quality of service and architecture of differentiated services are described in this thesis. Based on these facts, there was created a toolbox. This toolbox allows to create a dynamic network, which can be configured via using GUI. In the end of the thesis, there are shown results of the simulation of networks, which is running in created program.

Main accomplishment of this master’s thesis is to make a module for verification of the function binary and analog inputs (analog inputs only for current loop between 0-20mA) on data logger MODAS DataPoint. Hardware testing device will be made on development kit STM32F3-Discovery from STMicroelecronics Company. Device generates testing signals for confirmation of the function MODAS DataPoint device. Testing device communicates with MODAS DataPoint device via Ethernet, communication between PC application and hardware of the testing device is realized by USB interface in DFU mode. Solution included PC application, where you can connect to the tester device and tested Modas DP device. Furtheremore, the test starts here and application inform user about during a test, processed measured data and generate output protocols.

The main goal of this work is to make complete project of a computer network for Less & Timber s.r.o. The project will contain all information, from the cable traces, connection units, sockets and their count.

The work deals with the measurement of electrical quantities, distribution of data across the Ethernet network into the Internet and intelligent selection of the required values to be transmitted and stored on a central node. The work describes the communication protocols in scale that is necessary for implementation, discussed the requirements for computational resources and microcontroller control is proposed by flowcharts. Attached are source codes in C programming language for microcontroller and PHP scripts for storing and presenting data on Web server.

This thesis is about development and construction of systems for building automation. At the beginning it´s focused on usage of building automation. Short describe used topology of installation and available systems on the market. The second chapter is about designing of hardware’s elements systems. Then it’s describing control unit Raspberry Pi 3, microprocessors for communication and slave modules. For my thesis I am also engaged in interface communication and designing of I/O systems. The third and fourth chapter is describing software equipment’s of the system. The parts of microprocessor firmware and manner of control logic creating and visualization in control unit module are described in details. Last chapter contains the description of construction of testing module and measuring of system parameters.

Für die Implementierung von Hochgeschwindigkeits-LANs bieten sich gegenwärtig zwei Technologien an. Dies ist zunächst der verbindungsorientiert arbeitende Asynchronus Transfer Mode (ATM), welcher u.a. garantierte Bandbreiten ermöglicht und auch für WAN-Anwendungen einsetzbar ist. Ein Nachteil von ATM ist die Inkompatiblität zu den verbreitetsten LAN- Technologien, Ethernet und Token Ring. Für die Kopplung mit solchen LANs müssen spezielle Server herangezogen werden. Im Gegensatz dazu steht Gigabit Ethernet (GE) als Weiterentwicklung des Ethernet-Standards (IEEE 802.3). GE arbeitet verbindungslos und ist kompatibel zur Ethernet-Familie und anderen IEEE 802 konformen Technologien. Mit der Verfügbarkeit der IEEE-Standards 802.1p, 802.1x, 802.1Q und 802.1D sowie proprietären Mechanismen können mit Gigabit Ethernet LANs aufgebaut werden, die ATM-ähnliche Eigenschaften besitzen. Durch den Einsatz des TCP/IP Protokolls, welches traditionell in Netzen zur wissenschaftlichen Datenverarbeitung Verwendung findet, bleiben Eigenschaften, vor allem von ATM, verborgen. Dies betrifft insbesondere die dynamische Anforderung von Bandbreitengarantien (QoS).
