Protection and Logic Functions
Front-Panel Settings (SET F Command)
Unlike binary quantities, the relay displays analog quantities on both display
lines. Table 4.63 shows an entry in the Name string only (leaving the User
Text and Formatting string void) with the following syntax:
Figure 4.69 shows the front-panel display for the entry in Table 4.63 , using the
SET F command as follows:
DP01 := RID, “{16}”
? AI301 <Enter>

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 4.64 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:
DP01 := RID, “{16}”
? IN101,"INPUT IN101:" <Enter>
DP02 := TID, “{16}”
? AI301,TEMPERATURE: <Enter>
where:
Name = Analog quantity name (AI301 for example). All analog
quantities occupy two lines on the front-panel display
(all binary quantities occupy one line on the display).
User text and
numerical
formatting
= Display the user text, replacing the numerical
formatting {width.dec,scale} with the value of Name,
scaled by “scale”, formatted with total width “width”
and “dec” decimal places. Name can be either an analog
quantity or a Relay Word bit. The width value includes
the decimal point and sign character, if applicable. The
“scale” value is optional; if omitted, the scale factor
is 1. If the numeric value is smaller than the string size
requested, the string is padded with spaces to the left of
the number. If the numeric value does not fit within the
string width given, the string grows (to the left of the
decimal point) to accommodate the number.
