Abstract:

The complexity of industrial internet of things devices increases since new network protocols should be incorporated while still maintaining backward compatibility with existing protocols. When the complexity of the devices increases, the need for testing also increases, which can be performed using fuzz testing. Fuzz testing is a highly automated testing technique that has developed to become a fast and efficient way of detecting bugs in different systems, including network protocols. In this thesis, a complete fuzz testing framework is developed, which considers and motivates both the choice

Abstract:

The protocol of Digital Addressable Lighting Interface (DALI) was established in the early 1990s by a conglomerate of lighting product manufacturers to replace the original 0-10 V lighting control systems. It was designed as an open standard substitute to Digital Signal Interface (DSI), on which its structure is based [1]. The scope of this project was to control the lighting in the Murdoch University, South Street Campus, Western Australia by using a chosen controller to connect those modules to the chosen Schneider Enterprise/Automation server in the most efficient manner.

Abstract:

Communicating devices are on the rise. Fueled by the introduction of Internet-of-Thing (IoT) and Industry 4.0, more and more devices are capable of information sharing. There is a long history of communicating devices in industrial and building management contexts that previously relied on fieldbuses. One of these legacy fieldbuses is the Modbus protocol, originating in serial communication and now adapted for use with Ethernet. It has significant adoption in the fields of industrial automation systems (IAS) and building management systems (BMS) but carries many limitations. Industrial systems

Abstract:

This diploma thesis is focused on problematics of the industrial networks and offered security by the industrial protocols. The goal of this thesis is to create specific methods for detection of security incidents. This thesis is mainly focused on protocols Modbus/TCP and DNP3. In the theoretical part, the industrial protocols are described, there are defined vectors of attacks and is described security of each protocol. The practical part is focused on the description and simulation of security incidents. Based on the data gathered from the simulations, there are identified threats by the int

Abstract:

This diploma thesis explains the principle of SCADA systems and describes the DLMS/COSEM protocol. In the next part, it shortly describes the Modbus protocol and details the pros and cons of the Modbus protocol in comparison with the DLMS/COSEM protocol. In the next part, an open-source automated scanner was created. This scanner detects devices in a laboratory network. As the next step, the automated scanner finds out open ports and active services, which run on these devices, and tries to attack HTTP, SSH, and Telnet services. Next, the program checks, whether the found device is a smart-met

International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada<br>This article presents a measurement system based on the RS-485 interface. The presented system is an alternative solution for distributed measurement systems, which cannot be built using IEEE-488 interface due to distance limitation between elements of the system. The RS-485 interface is a base for communication between measurement instruments and uses a Master-Slave protocol to exchange data between them. One dedicated master device, usually a PC, controls all sl

Abstract:

This diploma thesis is focused on the analysis of the most well-known industrial protocols and acquaintance with the Dobot Magician robotic arm. The main goal of this thesis is to create an industrial loop, which consists of communication – client and server. The individual components of the industrial loop consist of three robotic arms (including peripherals), their control units (in our case Raspberry PI 3B +), switch, and a server. The control units communicate with the server using two selected industrial protocols, namely Modbus TCP and EtherNET/IP. The result of the work is an endless lo

Abstract:

In control technique there is evident highly expressive trend of shifting from efficient central managing systems towards smaller systems which are distributed on technology and which are connected by communication bus. There is no need to link all signals to central management system, operation is then distributed and realized directly in individual parts of technology. That’s why these systems are called distributive managing systems. Distributive managing systems are widely used not only in industrial applications but also in buildings, cars, etc..

The function of the protection relay is to capture running data, to provide protection against possible damage, to control an electric motor and to communicate this data to the System Control and Data Acquisition (SCADA) system in a control room. In the case of remote sites e.g. a pump station, the protection relays are used as standalone units. The protection relays are equipped with communication facilities to be used in an instrumentation environment. If a trip occurs or settings n
