Use the following syntax to display the given Relay Word bit with the given alias.
If the Relay Word bit is asserted (logical 1), the LCD displays the set string in the
place of the value. If the Relay Word bit is deasserted (logical 0), the LCD dis-
plays the clear string in the place of the value. One or all of Alias, Set String, or
Clear String can be empty. If Alias is empty, then the LCD displays only the Set
or Clear Strings. If either Set String or Clear String is empty, then an empty line
is displayed when the bit matches that state. The text size determines if the dis-
play will be in single font or double font. If the text size is empty, the display will
be in single font.
DPxx := Name, “Alias”, “Set String”, “Clear String”, “Text Size”
Use the following syntax to display the given analog quantity with the given text
and formatting. Formatting must be in the form Width.Decimal,Scale with the
value of Name, scaled by “Scale,” formatted with total width “Width” and “Deci-
mal” decimal places. The width value includes the decimal point and sign charac-
ter, if applicable. The “scale” value is optional; if omitted, the scale factor is
processed as 1. If the numeric value is smaller than the field size requested, the
field is padded with spaces to the left of the number. If the numeric value will not
fit within the field width given, “$” characters are displayed. The text size deter-
mines if the display will be in single font or double font. If the text size is empty,
the display will be in single font.
DPxx := Name, “(Text1 Width.Decimal,Scale) Text2”, “Text Size”
