Example 2:
Variable = feedback, range = -200% to +200%.
Range needed for output = 0–100%.
Output signal 0 mA or 4 mA is needed at 0% (50% of
range). Set
parameter 6-51 Terminal 42 Output Min Scale to
50%.
Output signal 20 mA is needed at 100% (75% of range).
Set
parameter 6-52 Terminal 42 Output Max Scale to 75%.

Example 3:
Variable value = reference, range = minimum reference–
maximum reference
Range needed for output = minimum reference (0%)–
maximum reference (100%), 0–10 mA.
Output signal 0 mA or 4 mA is needed at minimum
reference. Set
parameter 6-51 Terminal 42 Output Min Scale
to 0%.
Output signal 10 mA is needed at maximum reference
(100% of range). Set
parameter 6-52 Terminal 42 Output
Max Scale to 200%.

6-53 Terminal 42 Output Bus Control
Range: Function:
0 %
*
[0 - 100 %] Holds the level of output 42 if controlled by
bus.
6-54 Terminal 42 Output Timeout Preset
Range: Function:
0 %
*
[0 -
100 %] Holds the preset level of output 42.
If a timeout function is selected in
parameter 6-50 Terminal 42 Output
, the output
is preset to this level if a fieldbus timeout
occurs.
6-55 Terminal 42 Output Filter
Option: Function:
The following readout parameters from selection in
parameter 6-50 Terminal 42 Output have a filter
selected when parameter 6-55 Terminal 42 Output Filter

3.8.7 6-6* Analog Output X30/8
Analog outputs are current outputs: 0/4–20 mA. Common
terminal (terminal X30/8) is the same terminal and
electrical potential for analog common connection.
Resolution on analog output is 12 bit.
