Lecture
This lecture covers the principles, operation, and standard field buses of industrial communication networks, focusing on the hierarchy of networks in automation, the original idea behind field buses, and the advantages of using a field bus. It also discusses different classes of field buses, field bus applications in locomotives, drives, cars, and electricity network control. The lecture delves into the engineering of a field bus, including data density considerations, assessment of field bus expectations, and the importance of time-stamping and synchronization. It concludes with a comparison of cyclic versus event-driven transmission, the role of Ethernet in industrial communication, and the future of field buses in the context of operational technology (OT) and information technology (IT).
