Thus a change to all output stages of the
I/O module occurs at the same time.
Furthermore, D/A (digital-to-analog)
conversion is coupled to the local bus

synchronously with the local bus.

hidden and thus not visible in the fieldbus
process image.
With the "Extended" setting, the
control/status byte is shown on the fieldbus
process image. Thus the diagnostic
messages in the status byte can also be

evaluated by a higher-level controller.
Note: Changing the setting causes an
automatic restart of the node, since the
process image of the head station changes.

If the wiring is faulty, the outputs switch off
for about one second to prevent the

destroyed. After this, the system checks
