Time critical communication networks: field buses

Wireless Technology in Industrial Networks

“…6 The goal of this standard was to create a very low cost, very low power, two-way wireless communication solution that meets the unique requirements of sensors and control devices [20], [21]. In contrast to BT and IEEE 802.11, IEEE 802.15.4 has been specifically developed for use with applications in which a static network exists that has many infrequently used devices that transmit only small data packets.…”

Stabilizing a linear system by switching control with dwell time

“…Such networks can replace the point-to-point connections that have been conventionally used, and, as a result, reduce the number of wires and the cost for maintenance tasks [19], [21]. There are many industrial applications in which control networks have been successfully implemented, such as robotic systems [5], [12], networks on automobiles [14], [16], jacking systems for train cars [1], to name a few.…”

Das Internet in der Automation — eine Herausforderung für die Regelungstechnik

“…Erst in der jOngeren Vergangenheit hat die Regelungstechnik begonnen, industrielle Kommunikationsnetze, zumeist Feldbusse, als Mittel des Signaltransports auch innerhalb von Regelschleifen zu akzeptieren (Pleinevaux, Decotignie, 1988). Zu Beginn der Feldbus-Ara war die regelungstechnische Anwendung von Netzwerken noch auf wenige spezielle Bereiche (etwa die Antriebstechnik) und hoch spezialisierte Busse (z.…”
