Automatizace tvorby SW řídicích systémů / Automation of software control systems

Sysel, Radek January 2015 (has links)
The diploma thesis is about the design process of complex objects in automation and their rapid inclusion in the entire process technology. It shows the proces of creating a database model to generate into the SCADA application. The aim of the thesis is to show what all is needed to create, to produce a functional visualization model connected to the control system PLC. There is the analysis of the automated system change management, when it is processing technologies developed and we must do it based on customer feedback and revisions add new objects.

Vyhodnocení spotřeby osobní lodi / Passenger vessel consumption computation

Drbohlav, Lukáš January 2012 (has links)
This thesis is focused on a design and an implementation of a power consumption computation for a passenger vessel using the industrial automation system Siemens Simatic S7-200 and the touch panel Weintek Easy View MT8150X. A part of the thesis represents a theoretical summary of features and parametres of the programmable logic controllers (PLC) and a way how they are programmed. The work includes a description of a computational algorithm, a block diagram of interconnections and a visualization software for testing. A greater part of this publication is devoted to a detailed decription of a program in the PLC and its visualization, especially the power consumption computation, a distance, an average speed and a wind speed and a direction. At the end, the thesis shows a procedure for an implementation and a measurement on the passenger ships at the Brno dam, including an evaluation of downloaded data.

Převod vizualizace WinCC do MES systému COMES / Conversion of WinCC screens to manufacturing system COMES

Kárník, Jiří January 2016 (has links)
Presented thesis describes visualization of industrial processes. It focuses especially on the conversion of visualized data between Siemens Simatic WinCC and XML format. Build-in script editor is used to do aforementioned operations. Conversion and implementation of the data to the MES system COMES is solved in the next section of the thesis. Thesis also contains analysis of both used industrial systems and solves graphic format selection, which will be used to display image data in system COMES

Komplexní systém řízení výroby stroje plnící linky lahví / The complex control system of production of bottle filling line machine

Karola, Ladislav January 2012 (has links)
The Master’s Thesis is focused to introduction MES systems and factory information systems. Describes main advantages of applying MES systems and describes concept of Six Big Losses, which characterise main losses in production. For quantification of losses are used indicators like OEE. Next part is simulation data of Filler Machine and producing via OPC Server. Main application made in software SIMATIC IT by Siemens is collecting, processing and archiving data to PPA database due to rules and setups. Presentation of data is powered by Data Report which provides overview of efficiency and main losses in production.

Využití softwarového PLC v tepelné technice budov / Use of the software PLC in thermal engineering of buildings

Hubený, František January 2012 (has links)
This presenting master’s thesis deals with a problem of digitaly controled room temperature using the software PLC. The result of this work was creating of an algorithm to control temperature on the requested leve ofl setpoint, minimizing operating costs of the building. The PLC softwares from different manufacturers were analyzed and compared with conventional PLC. The testing facility was disigned and used to control the temperature in the room and data visualization. Room temperature was regulated by PS controller or two point regulator.

Řízení polohového servomechanismu s nespojitou přestavnou rychlostí. / Position control of servo with discontinuouns rechangeable speed

Jindra, Pavel January 2012 (has links)
Diploma thesis work includes simulation of compensation of control for discrete. The aim of the work is a solution positioning control of servomotor drive piston, which is controlled by pass of the pressure oil with the help of several electromagnetically controlled switchboards with the orifice in the output channels. The verification activities of the regulated system is done using simulation in Matlab/Simulink and Matlab/Simulink, Matlab/Hydrosim. The requirement on the created model is to verify the behavior of the system to be modified to be used for the further development of the issue

Řízení balícího stroje s použitím Safety PLC / Control of packaging machine using Safety PLC

Žiak, Martin January 2017 (has links)
This thesis deals with a technology of continuous packaging machine in the beginning from the point of risk assessment and design of necessary measures to reduce the risk as much as it is possible. Here the HRN method was used to quantify every risk factor. Next part documents the implementation of the safety measures and the realization of the safety circuits by using Simatic S7–1500F safety PLC and Shared device functionality. Safety function which is realized in the Sinamics S120 drive is Safe Stop 1. Next, it describes the drive dimensioning and the principle of the drive control. Simotion PLC is discussed in more details and then is used as a motion control master. An approach to the configuration of camming synchronous operation is dealt with in details. Cam design and their realization is documented, too. The thesis also demonstrates the state manager that was implemented in the user program and which is used according to the concept of OMAC state manager. In the end a simple HMI for packaging machine control is described.
