OPC UA client in Python
Zmrzlý, Jan ; Parák, Roman (referee) ; Lang, Stanislav (advisor)
OPC UA (Unified Architecture) is a modern industry communication standard. This is an expected evolution following the successful OPC Classic protocol. Nowadays, the majority of devices with these technologies are able to communicate with the server model server – client. The purpose of this bachelor's thesis is to summarize the knowledge about the OPC UA industry standard and the creation of an OPC UA client in the Python programming language. The client's functionality is verified on communication with the B&R PLC.

Data processing from the online diagnostic system
Cirhanová, Iva ; Jankových, Róbert (referee) ; Zuth, Daniel (advisor)
This master thesis deals with data processing from an online diagnostic system. The theoretical part of the work is divided into three chapters, the first deals with technical diagnostics as such, there are basic terminology and concepts associated with technical diagnostics, such as diagnostic methods, tools, models and signals. The second part is focused on diagnostic systems and their division. This chapter also provides some examples of online diagnostic monitoring systems from three different companies. The last chapter of the theoretical part is devoted to the description of the possibilities of data collection from diagnostic systems, ie. description of communication buses and protocols. The practical part of this work focuses on creating an application for data collection and visualization.

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.

Software Support for PLC Automation Systems
Kříž, Karel ; Ševcovic, Jiří (referee) ; Chmelař, Petr (advisor)
This thesis mainly deals with the study of communication protocols between process control systems of company Siemens and their superstructural systems (SCADA/HMI) the Ethernet interface. This is a management systems, which are mainly used by Aucon s.r.o. in practice. It also deals with OPC servers, and their use with client applications. Emphasis is placed on the theoretical analysis of certain types of inter-processcommunication in Windows. From the simple one to the model COM, which is the basis of the OPC technology. Practical part realize implementation of a simple programming interface, providing communications with equipment Siemens Simatic S7. This is realized by C++ with using WinSock2 a IPHlpApi libraries. This interface can be used at programming client application.

Web control system for textile machine
Balázsy, František ; Jirgl, Miroslav (referee) ; Arm, Jakub (advisor)
This thesis deals with the design and implementation of web control application for textile machine. It consists of an HMI application based on the VueJS and Electron frameworks which communicates with the B&R PLC using the OPC UA protocol. For programming and production management uses MES microservice based on web realtime API. After it deals with deploying the application to a Linux station with kiosk configuration. The whole stack is implemented using JavaScript programming language and open-source software resources exclusively.

OPC UA Client for "Sorter of Boxes" Laboratory Model
Magáth, Marek ; Arm, Jakub (referee) ; Jirgl, Miroslav (advisor)
This bachelor’s thesis is about OPC comunication protocol, specifically the newest specification OPC UA (Unified Architecture). By creating OPC UA client application using the OPC UA .NET libraries offered by the OPC Foundation for free. Setting up the OPC server on the S7-1500 PLC using the TIA Portal V14. Part of the work is done by modifying model Třídička beden, specifically with the modification motor control and creating more complex control task for this model. Next, by creating a control program in the Ladder Diagram, where I specifically describe some solutions of problems. And also by creating visualization on the touch panel TP700 Comfort. The visualization is created in WinCC, which is part of the TIA Portal. Finally, I describe how to link the OPC UA client created together with the touch panel and the PLC that control this model. And how to collect or observe the process data.

Differentiation potential of polydendrocytes in pathological states of central nervous system
Pavlištová, Tereza ; Anděrová, Miroslava (advisor) ; Smejkalová, Terézia (referee)
NG2 cells also called polydendrocytes or oligodendrocyte progenitors comprise fourth type of glial cells in the brain. Ng2 glia express distinct markers on their cell surface, which can be used for their identification. Particularly, NG2 proteoglycan chondroitin sulphate and receptors for platelet-derived growth factor belong to the main markers. Polydendrocytes arise in two canals of spinal cord and also in the ventral part of frontal brain, telencephalon and diencephalon. Population of NG2 cells is heterogeneous because they differ morphologically, by their electrophysiological properties and distinct differentiation potential depending on localization in brain. In conditions in vitro, polydendrocytes can differentiate into oligodendrocytes, protoplasmic astrocytes or neurons. In early postnatal brain, NG2 glia give rise to astrocytes, but most of these cells remain in the mature state or change themselves to oligodendrocytes. Pathological states of the central nervous system cause an activation of polydendrocytes, they start to be hypertrophied and increase expression of NG2 proteoglycan. Reaction of these cells is influenced by environment and chemical factors, for example growth factors, morphogens and cytokines. Depending on the type of CNS disorder the differentiation potential of NG2 glia...

Mobile Accessing of Automation Data (Front-End Development)
Kubiš, Jan ; Kolář, Dušan (referee) ; Květoňová, Šárka (advisor)
Content of this report describes design, implementation and functionality of a web application, which was developed within bachelor thesis and which purpose is to collect, transfer and present data from devices that are able to provide the data according to OPC standard specification (OLE for Process Control - Object Linking and Embedding for Process Control). The application makes use of client-server architecture. Application back-end is implemented in C# and front-end, which is the subject of this report, uses combination of programming, scripting and markup languages C#, JavaScript, HTML and SVG. Application is being developed for ABB company (who is owner of all source codes) and it is expected to be put into operation in commercial sector. Supported platform is operating system Microsoft Windows 10.
