End-to-end reliability for Wireless Sensor Network communications is usually provided by upper stack layers. Furthermore, most of the studies have been related to star, mesh, and tree topologies. However, they rarely consider the requirements of the multi-hop linear wireless sensor networks, with thousands of nodes, which are universally used for m...
The ongoing trend to move industrial appliances from previously isolated networks to the Internet requires fundamental changes in security to uphold secure and safe operation. Consequently, to ensure end-to-end secure communication and authentication, (i) traditional industrial protocols, e.g., Modbus, are retrofitted with TLS support, and (ii) mod...
In the past centuries, production processes have impressively evolved from mostly hand-made goods of small quantities to almost fully automated large scale productions. Three significant jumps are commonly referred to as industrial revolutions, which have brought first mechanization, then electrification, and in this century, partial automation to ...
Komunikace hraje v dnešním světě plném technologií klíčovou roli a informace představují nemalou hodnotu. Do průmyslového prostředí je na všech úrovních čím dál více zaváděna automatizace. Zařízení od senzorů a akčních členů až po pracovní stanice poskytující přístup k plánování a diagnostice systémů musí být připojená k síti a vzájemně si vyměňova...
Fueled by the growing global competitive pressure, future industrial systems require a much higher degree of exibility and reliability. The increasing complexity necessitates a paradigm shift towards a service-oriented organization of manufacturing processes, commonly associated with the keyword Industry 4.0. The higher exibility results from using...

Tématem této diplomové práce je heterogenní komunikace v řídicích systémech firmy ABB. Veškerá práce se soustředí na protokol Modbus, komunikaci pomocí tohoto protokolu v systémech 800xA firmy ABB a na testování projektů při použití zmíněného protokolu. Hlavním cílem práce je zajistit a demonstrovat možnosti testování komunikace, při použití výše z...
The paper presents the concept and implementation for Cloud-based Industrial Control Services (CICS) as a next generation PLC. As a distributed service-oriented control system in the cloud, a CICS controller can replace the traditional PLC for applications with uncritical timing in terms of Industry 4.0. The CICS services are programmed to industry...
In contrast to the predecessors, the fifth generation of mobile networks (5G) will particularly address communication in production systems by providing machine-type communication and matching requirements regarding reliability and latency. However, 3GPP 5G will not be the one and only network technology that can be used to fulfill all the requirem...
