Bridge type of track shifter
Jílek, Roman ; Fiedler, Petr (referee) ; Štohl, Radek (advisor)
The aim of this Master's thesis is characterization Programmable Logic Controllers, description of Industrial interface – AS-Interface, assembling electronic components at construction of model of bridge type track shifter and programming model. First part is focused to Programmable Logic Controllers their qualities, characterization and separation and describing AS-Interface and its components. Second part is describing equipment and locations of equipment. Third part is about software. Fourth part is describing programming. Next part is about visualization and last part contains instructions for laboratory work.

Automatic barman
Podrabský, Tomáš ; Horna, Jakub (referee) ; Štohl, Radek (advisor)
I was working on a project of the automated bartender, whose construction has already been done. At the beginning I had to acquaint with construction and understand how it should work. I created the software in developmental environment CoDeSys in version 2.3 and later in version 3.5. Both of them allows the program creation, as well as visualization and online monitoring of PLC operation and debugging. PLC communicates via AS-interface. The aim of this project was to create fully functional application for barman. PLC program is structured as a state machine, which is ideal for this application. State machine is written in the developmental environment in language SFC and its individual steps in LD, ST, or FBD. I focused on simplicity and clarity of the program, in which I tried to incorporate as many features as possible. I managed to create a program that is able to tap one of the 4 or mix of any number of drinks. It can be also said that the operator doesn't want a full glass, but fewer doses than the maximum. The main acquisition for me was the fact that I was able to solve the problem independently, using the programmable controller on a real system, which gave me lots of new skills. The result of this work is fully functional automated barman including visualization that shows the status of sensors, the number of doses for individual drinks and allows to control the whole system and check error messages.

Add-on instructions for AS-Interface Network
Grepl, Tomáš ; Fiedler, Petr (referee) ; Štohl, Radek (advisor)
This master's thesis deal with design and creating of the instructions for industry bus AS-Interface. These instructions were implemented in the software ControlLogix5000 like add-on instructions. In the teoretical part there are presented the issues of industrial control, AS-Interface bus, add-on instruction and model of the labyrinth. The practical part of the master's thesis is focused to design of the add-on instruction and work with instruction and its characteristics followed by the description of the sample add-on instruction and the list of all implemented instructions. The final two chapters include visualization and laboratory exercise.

Bridge type of track shifter
Holomek, David ; Franek, Lešek (referee) ; Štohl, Radek (advisor)
This Bachelor thesis contains a description of a bridge type track shifter model, with the introduction including an analysis of the whole work. The first task describes the look and layout of individual parts of the track shifter model. There is also a description of the AS-Interface database, as well as a section with representations of the sensors and actuators of the track shifter. The fifth part describes the PLC software configuration, and is followed by a section dealing with the errors found in the AS- Interface database. After a description of the track shifter’s control program, the seventh section underlines the visualization aspect of the track shifter model. The final section includes samples of laboratory tasks.

Communication by PLC with peripherals of model elevator
Goryl, Stanislav ; Hynčica, Ondřej (referee) ; Štohl, Radek (advisor)
The theme of this bachelor thesis was to create firmware for internal and external control panel for a model of a lift. Control panels communicate with the upper-level control system via the AS-Interface fieldbus. The base of the firmware is the finite state machine. In the introduction of the thesis, there is a brief description of the AS-Interface bus and the outline of the principle of data transfer. Followed out, is the description of firmware for control panels. Furthermore, there was created a test application for PLC which verifies the functionality of control panels. In the last part, there was produced a manual for the firmware programming, including the construction of untypically involved programming cable.

Add-on instructions of the AS-Interface for the conveyor
Püschel, Robert ; Foukal, Roman (referee) ; Štohl, Radek (advisor)
The aim of the bachelor‘s thesis is to acquaint readers with a creation of Add-On Instructions in the development environment Studio 5000 for the industrial network AS-Interface, to which the conveyor model is connected. The thesis is divided into a theoretical part dealing with the description of the AS-Interface network, the operation of the Add-On instruction and the conveyor model and a practical part that describes the specific creation of Add-On instructions, their logic, demonstration in a task and a complete list.
