Name String Only
Name and Alias
For a more descriptive name of the Relay Word bit, enter the Relay Word bit
in the Name String, and an alias name in User Text and Formatting String.
Table 4.58 shows a Boolean entry in the Name and Alias Strings (DP01) and
an entry in the Name and User Text and Formatting Strings (DP02), using the
SET F command as follows:
Figure 4.76 shows the front-panel display for the entry in Table 4.58. 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 as
shown in Figure 4.77.

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, i.e., DP01 = 1,“DEFAULT”
and DP02 = 1,“SETTINGS.” Table 4.59 shows other options and front-panel
displays for the User Text and Formatting settings.
