Zusammenfassung:The invention relates to an ethernet device (100, 200) with safety features at the physical layer and a method for a bi-directional data transfer between two ethernet devices (100, 200), wherein at least one of the two ethernet devices (100, 200) is an ethernet device (100, 200) with safety features at the physical layer according to the invention. The ethernet device (100, 200) can switch safety critical traffic from a first ethernet channel (120) to a second ethernet channel (140) is a safety problem has been detected for the first ethernet channel (102). L'invention concerne un dispositif Ethernet (100, 200) doté de fonctions de sécurité au niveau de la couche physique et un procédé de transfert bidirectionnel de données entre deux dispositifs Ethernet (100, 200), au moins l'un des deux dispositifs Ethernet (100, 200) étant un dispositif Ethernet (100, 200) doté de fonctions de sécurité au niveau de la couche physique d'après l'invention. Le dispositif Ethernet (100, 200) peut commuter un trafic critique de sécurité d'un premier canal Ethernet (120) à un second canal Ethernet (140) si un problème de sécurité a été détecté par rapport au premier canal Ethernet (102).
