Analýza řídících protokolů využívaných v průmyslových aplikacích / Analysis of distributed control protocols for indistrial applications

This master's thesis deals with distributed control protocols for industrial applications. It explains term distributed control system, control protocol and it is dealing with properties, frame structures and ways of communication within CAN, Modbus, IEC60870-5-101 and DLMS protocols. This thesis includes informations, which are in most cases difficult to find. Second part of the thesis is dedicated to education system. This part is contained by information about protocols and their layers based on ISO/OSI model, pictures of structure of messages, knowledge test and an application based on JavaScript language. This JavaScript application emulates behavior of workstations, which are using communication based on IEC 60870-5-101 protocol. This application can set various conditions for influence of message transfer. These conditions are setting way of message transfer, data availability, filling of workstation’s buffer or intentional damage of message's content. It also contains a large amount of context help, activated after moving mouse cursor over most of application's elements. Even visitor without great knowledge of distributed control systems should understand how this protocol works, thanks to these context help and messages printed in lower part of the application. The conclusion of this work is aimed to positive and negative features and comparison of mentioned control protocols.
