US 2006/0067208 A1 · Method and device for medium-redundant operation of a terminal in a network

Abstract

The invention relates to a method and device for medium-redundant operation of a terminal in a network. The device comprises: a first transmission device (6) of a physical bit transmission plane which is connected to a network component (9) via a first connection medium (8) disposed between the first transmission device (6) and a network component (9) and which can produce an error signal during automatic monitoring of link to the network component (9) if no physical link or if a defective link to the network component (9) exists; another transmission device (7) on the physical bit transmission plane, which is connected to the network (4) via another connection medium (10); and a control device (5) which is connected to the first transmission device (6) and the other transmission device (7) in order to deactivate the first transmission device (6) as a reaction to the error signal therefrom, enabling activation of the other transmission device (7) and enabling an electronic error telegram to be sent to the network (4) via the other connection medium (10) by means of the other transmission device (7). The invention also relates to a method for operating said device.

Dependent claims

A method for media-redundant operation of a terminal in a network:

automatically monitoring, via a first transmission devices in the terminal, which is connected to a media access controller for the terminal, a connection which is formed between the first transmission device and a network components via a first connecting medium;
producing, from the first transmission device, a failure signal if no connection or a faulty connection is found via the connecting medium during automatic monitoring of the connection, and
as a reaction to the failure signal,
deactivating the first transmission device via a control device (5) which is connected to the first transmission device;
activating, via the control device, a further transmission devices, which is connected to the media access controller for the terminal, with a sound physical connection being reproduced between the terminal and the network via a further connecting medium, and
sending an electronic failure message by means of the further transmission device via the further connecting medium to the network for registration of the further transmission device.
