7.4.1.2.1.1.14.1 Dependent Parameter
Number of temperature input objects
This parameter is visible if, in the Temperature input parameter, the Via group object or Via physi-
cal device input and group object option has been selected.
Options:
This parameter is used to specify the number of group objects that can receive temperature values
via the bus.
• 1: If this option is selected, the External temperature 1 group object is enabled.
• 2: If this option is selected, the External temperature 1 and External temperature 2 group ob-
jects are enabled.
Using these two objects, temperature values measured using other devices can be received; these
values are then used to determine the actual temperature.
If the 1 option has been selected and in the Temperature input the Via physical device input and
group object option is not selected, the temperature received in the External temperature 1 group
object is the actual temperature. If the 2 option has been selected, the dependent parameters
Weighting of external measurement 1 and Weighting of external measurement 2 are enabled.

7.4.1.2.1.1.14.2 Dependent Parameter
Internal measurement weighting
This parameter is only visible if, in the Temperature input parameter, the Via physical device input
and group object option has been selected.
Options:
This value specifies the weighting with which the internal measurement is to flow into the calcula-
tion of the actual temperature.
—
7.4.1.2.1.1.14.3 Dependent Parameter
Weighting of external measurement 1
This parameter is only visible if both the following cases apply:
• In the Temperature input parameter, the Via physical device input and group object option has
been selected.
• In the Temperature input parameter, the Via group object option has been selected and in the
Number of temperature input objects parameter, the 2 option has been selected.
Options:
This value specifies the weighting with which the external measurement 1 is to flow into the calcu-
lation of the actual temperature.
