<p>The control and data transmission system (5) includes at least one serial field bus (10), with an associated control unit (20) and several bus subscriber units (30,40,50). A single supply cable (69) connects a central power supply unit (68) to logic components (34,38,70,80) as well as to load components (110,120). The control and data transmission system includes at least one safety switch (80) which, based on a reported fault, switches off all faulty logic components and/or all faulty load components by disconnecting them from the central power supply unit.</p> |
