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.
