This thesis deals with the design and subsequent realization of laser diode control devices. The circuit will be able to control the diode with using a laser driver, via a computer network or via the display for control current values, setting of initial values and more. The device will be connected also with a SD card for saving of settings. In the theoretical part there are described individual components that are needed for functionality of the device. The practical part contains a block diagram, in which is described complete feature of the device, then a draft scheme with a description of all integrated circuits and important components. At the end of this work is described the software that controls the entire designed device.

Different network devices require processing of the network traffic. To process the network traffic, it is necessary to parse headers of particular protocols packed in incoming ethernet frames. The processed headers can be repackaged to ethernet frames and sent back to the network. The goal of this thesis is to design and implement a circuit for analysis and parsing of ethernet frames, together with circuit for deparsing ethernet frames. The circuits are designed for throughputs of up to 400 Gb/s. The circuits are implemented for the FPGA technology.

This project describes the design of a system for remote temperature monitoring of stored a more commodities quantity for the horse-breeding. The main task of this system is the early alert before the fire developed to the spontaneous combustion and continuous monitoring of the quality and safety this commodities. The main module communicates with several autonomous temperature sensors, which are located in multiplie locations. The measured values can be stored on an internal memory, displayed on the display and transmitted with the Ethernet network to the client computer, where it is possible this temperatures to view with in the user program and graphs.

This diploma thesis deals with the study of leakage problems in industry and the use of Agilent weight detectors for its detection. Based on the studies conducted, a hardware and software solution has been proposed for connecting the measuring elements to a helium detector at a simple configurable station. Additionally, a C# application was created. This application allows the leak detector to be controlled and data collected from the detector and its surroundings. The created application was tested in a real environment. The conclusion of this work is devoted to the possibilities of using the created application.

This thesis deals with network substandards from the TSN group (IEEE 802.1Q), which deal with prioritization of network traffic in TSN networks. These sub-standards include 802.1QBV and 802.1QBU, which have been described in more detail and compared in terms of network permeability and latency. Substandard 802.1QBU was chosen for the design implementation in FPGA. The design was described in VHDL. The designed design was verified by simulations, using self-tests. The work includes synthesis and time analysis.

The performance of the virtual switch Open vSwitch (OVS) is insufficient to satisfy the current requirements for link bandwidth of the server connections. There is an effort to accelerate the OVS both in the software and in the hardware by offloading the datapath to the smart network interface cards. In this work the COMBO card for 100G Ethernet developed by CESNET is used to accelerate the OVS. The suggested solution utilizes the firmware for FPGA generated from the definition in the P4 language to classify the packets in the card and DPDK for the data transfers and offloading the classification rules into the card. Forwarding of one flow with the shortest frames from physical to physical interface using one CPU core reaches forwarding rate of 11.2 Mp/s (10 times more than the standard OVS) with classification in the card and 5.9 Mp/s without classification in the card.

This diploma thesis deals with the design and application of the ISA 95 standard for a semi-automatic barman machine. The thesis is divided into theoretical and practical part. The theoretical part deals with the description of the ISA 95 models, together with FactoryTalk platform and its products related to the ISA 95 standard. In the practical part batch procedure is designed and applied on the machine. Based on this, implementation of standard ISA 95 using Rockwell Automation products is made. The last chapter of this thesis deals with verification of functionality and overall system design, from which concludes an overall machine performance and production deficiencies.

This diploma thesis is focused on the analysis of the most well-known industrial protocols and acquaintance with the Dobot Magician robotic arm. The main goal of this thesis is to create an industrial loop, which consists of communication – client and server. The individual components of the industrial loop consist of three robotic arms (including peripherals), their control units (in our case Raspberry PI 3B +), switch, and a server. The control units communicate with the server using two selected industrial protocols, namely Modbus TCP and EtherNET/IP. The result of the work is an endless loop, which tries to resemble the real operation of the assembly and disassembly of the box equipped with dierent items.
