Abstract: The invention relates to a method for automated control of at least one machine component (1) in a plant (2). The machine component (1) is connected via a secure bus connection (6) to an automation component (7) by which it is controlled. The plant (2) has a safety area (4) monitored by means of at least one safety sensor (3), where a deviation of the measurement pattern (M) measured by the safety sensor (3) from a definition area (D) indicates a hazardous situation for protection objects (5), in particular persons and/or valuables. The machine component (1) triggers a protective action if a hazardous situation arises. The measurement patterns (M) measured by the safety sensor (3) are transmitted to the automation component (7) via the secure bus connection (6). The automation component (7) defines the definition area (D) using parameter data of the automated control, ascertains the presence of a hazardous situation, and activates the machine component (1) for performing the protective action.
