A one-way coupling device for the feedback-free transmission of data from the first network with high security requirements into a second network with low security requirements, containing a request unit, an eavesdropping unit and a receiving unit, wherein the request unit is formed so as to provide a first communication link within the first network to at least one device and, moreover, to request first data from the at least one device and then to transmit the first data via a second communication link on a separate line loop of the request unit, and the eavesdropping unit, which is formed so as to eavesdrop on data on the separate line loop and to transmit data to a receiving unit which is arranged in the second network. Also, a corresponding request unit, a corresponding method and a corresponding computer program product is also provided.
