Abstract
In a method and a device for redundant transmission of protection commands between remote tripping devices (), useful information which represents a protection command or a rest signal is transmitted by a first remote tripping device () in at least two time slots via a first interface () to a first multiplexer (), and is transmitted via different transmission paths () by the multiplexer () based on the time slots. A second multiplexer () receives the useful information via the different transmission paths (), and transmits each useful information item via a time slot, which is allocated to the respective transmission path (), in a second interface () to a second remote tripping device ().
