1. A safety-directed control system comprising:
at least one safety sensor unit;
at least one safety actuator unit, which is connected to the one safety sensor unit via a fieldbus;
a programming device connected to the at least one safety actuator unit via the fieldbus; and
processing circuitry;
wherein sensor connections for connecting safety sensors to the fieldbus are provided by the at least one safety sensor unit, and the sensor connections are associated with safety lines,
wherein the processing circuitry is configured to display available safety lines of the safely lines to a user via an output interface,
wherein the processing circuitry is configured to receive a user input of the user via an input interface, with the user input associating a selected safety response from safety responses, which is executable by the safety actuator unit, with at least one selected safety line of the available safety lines,
wherein the processing circuitry is configured to store the association between the at least one of the safety lines and the selected safety response in the safety actuator unit as a safety configuration,
wherein the safety lines associated with individual sensor connections of the sensor connections are configured to be independently activated by the at least one safety sensor unit by transmitting line activation signals of individual safety lines of the safety lines via the fieldbus,
wherein the safety actuator unit is configured to receive the line activation signals via the fieldbus directly from the at least one safety sensor unit,
on reception of a line activation signal of the line activation signals of an activated safety line of the safety lines, to independently execute the selected safety response stored for the activated safety line in the safety configuration, and
wherein the safety responses executable by the safety actuator unit are stored in the safety actuator unit and are configured to be retrieved by the programming device via the fieldbus for selection by the user.
