Zusammenfassung:Disclosed is a lighting control device (4), comprising a transmitter unit (41) connectable to a field bus (6) and configured to conduct a wireline transmission of the lighting control device (4) on the field bus (6) by intermittently applying a logic low signal level to the field bus (6). The logic low signal level comprises a positive voltage. The lighting control device (4) is configured for power intake off the field bus (6) when the positive voltage is present on the field bus (6). This improves the energy supply capacity of networked devices of a field bus.
