6 AVAILABLE REFERENCE VALUES
Information that you will find in
this chapter ...
This chapter gives you information on:
• the functions of the reference values that you can set as main reference value, additive
reference value and weighting factor
• when to use them
• and how to parameterize the functions.
To access the reference values, call the applicable page of the Assistant or go to page 4
and use the arrow keys to the left of parameters D30, D31 and D33.
6.1 Reference Value External, Correction Reference Value 1 and 2
Information that you will find in
this section ...
This section shows you:
• the conditions under which to use the reference values "reference value external,
correction reference value 1, and correction reference value 2"
• how the reference values are set up
• and how to parameterize the reference values.
When to use the reference
values …
Use the reference values if you want to constantly change the reference values (e.g., via
a potentiometer or via the analog output group of a PLC). The reference value can also
be transferred via fieldbus.
Structure
Figure 6-1 shows the structure of the functions "reference value external, and correction
reference values 1 and 2." The table at the end of the section lists the related parameters
for each reference value.

How to parameterize the
reference values ...
To parameterize a reference value, proceed as shown below:
• The source of the reference value signal can be set in the selector. You can supply the
reference value external and the correction reference values 1 and 2 via fieldbus or
analog input. Figure 6-2 shows page 3.1 of the Assistant for scaling the reference
value external. In our example analog input 1 (AE1) is set in D132 as the interface. All
parameters which you can use to modify the analog signal are listed. With fieldbus the
selection 4:parameter is made in the selector. The reference value is written via
fieldbus to the fieldbus parameter.
