Title (EN) POWER OVER ETHERNET IN A REDUNDANT RING DATA NETWORK
(FR) ALIMENTATION SUR ETHERNET DANS UN RÉSEAU DE DONNÉES EN ANNEAU REDONDANT
Abstract:
(EN) A process control system including a plurality of controllers and devices, the devices including I/O modules, sensor modules and actuators (1, 2, 3, 4, 5), which are connected to said system by a data communication network operated at least in part according to an Ethernet standard. The system also comprises one or more controller with an Ethernet switch functionality configured to support power over Ethernet (PoE). At least two said devices in a ring support power receiving on one first port and power supplying on a second port of a said device.
(FR) L'invention porte sur un système de commande de processus comprenant une pluralité de contrôleurs et de dispositifs, les dispositifs comprenant des modules E/S, des modules capteurs et des actionneurs (1, 2, 3, 4, 5), qui sont connectés audit système par un réseau de communication de données exploité au moins en partie selon une norme Ethernet. Le système comprend également un ou plusieurs contrôleurs à fonctionnalité de commutateur Ethernet conçus pour supporter une alimentation sur Ethernet (PoE). Au moins deux desdits dispositifs dans un anneau supportent une réception de courant sur un premier port et une fourniture de courant sur un second port dudit dispositif.
