Acyclic Profinet Communication between Sinamics Converters and Simatic S7-1200 PLCs
Dostál, Jiří ; Janda, Karel (referee) ; Pásek, Jan (advisor)
This paper deals with acyclic communication of Siemens Simatic S7-1200 PLCs and Sinamics drives on the Profinet industrial bus. Various possibilites of communication of the devices in accordance to the PROFIdrive profile is presented. General Proxy FBs for acyclic read/write of the drive's parameters are implemented. Together with other two FBs, that make use of acyclic communication to read the drive's fault buffer and to adjust an absolute encoder, an application with visualization for a simple positioning and for a demonstration of the Proxy FBs functionality is presented using a demo box.

Compiler of source code for SIMATIC PLC
Kubát, Zdeněk ; Kaczmarczyk, Václav (referee) ; Pásek, Jan (advisor)
The thesis discusses an independent compiler for STEP 7 and WinCC V7.0 applications of the SIEMENS company. The compiler processes source files generated in STEP 7 and subsequently saves the processed data in .xls type intermediatefiles. The data of the intermediatefiles serve as source data for functions generating files with tags to be imported into WinCC V7.0. The compiler was created using the C# programming language in Visual Studio 2010.

Control system for assembly and test automatic machine for electronics of car seats
Dočkal, Tomáš ; Zemánek, Pavel (referee) ; Pásek, Jan (advisor)
The thesis deals with definition of safety, traceability systems, creation of PLC programs for testing device control system and creation of Operator panel software. The thesis is divided into the machine specification and description, OP function description including function keys and the description of the control system with samples of the completed PLC program. The PLC program is written in STL and FBD language in STEP7. The conclusion describes functionality of the device.

Use of the software PLC in thermal engineering of buildings
Hubený, František ; Kaczmarczyk, Václav (referee) ; Pásek, Jan (advisor)
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.

The complex control system of production of bottle filling line machine
Karola, Ladislav ; Milan, Sobotka (referee) ; Pásek, Jan (advisor)
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.

Transfer and utilization of process data (PLC) in production control system
Kupčík, Michal ; Michal, Novotný (referee) ; Pásek, Jan (advisor)
This work explains to reader the difficulty of production scheduling and why is much advantageous using proper system for this work. Next he reads about complexity of production management and about necessity of linkage between all levels of company’s IT systems. We are going to use three different approaches for getting Siemens controller’s data out and for two of them we are going to describe general procedure, how we gets a data files, which are openable in classic table processor like MS Excel and which contain user’s choosen variables including their actual values. Finally reader will be familiarized with SimRead program, which serves for reading variable’s values in combination with Simatic standart communication blocks.

Control of batch process on recipe basis in SCL language
Vondráček, Jiří ; Milan, Sobotka (referee) ; Pásek, Jan (advisor)
The thesis is focused on the control of batch processes on recipe basis. The objective of this thesis is to create a philosophy of control batch processes using programming languages SCL and CFC. In the theoretical part of the work, the automation of production are explained and the principles of the control of batch processes based on recipes in accordance with standard S88 are described. In the last part there is a draft concept of such a procedure without the use of batch-oriented type systems like Batch is.

Decentralized Control of a Portal Crane by Means of PLC SIMATIC
Ribka, Jan ; Sobotka, Milan (referee) ; Pásek, Jan (advisor)
This master’s thesis deals with a total concept of decentralized control system for process control by means of PLC SIMATIC. This concept is demonstrated on a model of a portal crane in the introductory chapter. The second chapter is focused on industrial communication network PROFIBUS. Different types of this network and ways of communication are described. The third chapter is concerned with industrial communication network PROFINET (Industrial Ethernet). Different types of this network and ways of communication techniques are described. The next chapter presents components of Siemens company, which are necessary for creation of demanded control system. The following part describes the programming facilities for STEP 7 programs - Simatic Manager, Micro/WIN and WinCC flexible. It contains creation of the control system including communications on the networks.
