Description
Synchronous DA
conversion
Off
*)
If synchronous conversion is switched on,
the output channels are processed, not one
after another, but rather synchronously.
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
cycle, so the output values are updated
synchronously with the local bus.
On
Process image
Standard
*)
In the standard process image, the
control/status byte of the head station is
hidden and thus not visible in the fieldbus
process image.
Extended
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.
Diagnosis: Power
supply fault
Off
Switches the supply voltage monitoring
on/off If the supply voltage is faulty, a
corresponding error message is output in
the status byte of all channels.
On
*)
Diagnosis: Wiring
error
AO−
Off
Switches the wiring error monitoring for
outputs –AOx on/off
If the wiring is faulty, the outputs switch off
for about one second to prevent the
actuators on the field side from being
destroyed. After this, the system checks
whether the error persists.
