Front-Panel Settings (SET F Command)
Figure 4.156 shows the front-panel display for the entry in Table 4.87. Input
IN101 is deasserted in this display (0), and the display changes to
INPUT
IN101=1
when Input IN101 asserts.

Alias Strings and (b) Analog Name and User Text and Formatting Strings
If the engineering units are set, then the front-panel display shows the
engineering units. For example, in the Group setting example, we set
AI301EU to degrees C. With this setting, the front-panel display looks similar
to Figure 4.157.

Strings and (b) Analog Name, User Text and Formatting Strings,
and Engineering Units
For fixed text, enter a 1 in the Name String, then enter the fixed text as the
alias text. For example, to display the word DEFAULT and SETTINGS on two
different lines, use a display point for each word (DP01 = 1,“DEFAULT” and
DP02 = 1,“SETTINGS,” for example). Table 4.88 shows other options and
front-panel displays for the User Text and Formatting settings.
Following is an example of an application of the analog settings. Assume that
we also want to know the hot-spot temperature, oil temperature, and winding
temperature of the transformer at a certain installation. To measure these
