Abstract

A system, in particular for controlling signal towers in rail traffic, includes at least a plurality of redundant replicants for generating redundant control signals. A voter structure having a plurality of majority voters is also provided. Each majority voter has a respective output and inputs that are connected to the outputs of the plurality of redundant replicants. The voter structure and the plurality of redundant replicants are separated from one another in terms of hardware, the outputs of the plurality of majority voters are connected to the inputs of a discriminator voter and the output of the discriminator voter provides a control signal, in particular for controlling signal towers. The discriminator voter only emits a control signal when the inputs thereof are not at variance.
