d. Enter a comparison value. The default comparison value is 0. The comparison value can be
one of the following:
An integral or floating-point value if evaluating a scalar data point or a field within a
structured data point that has a scalar type.
A space-separated structured value (for example, 100.0 1) if evaluating a structured data
point as a whole.
An enumeration string (for example, HVAC_HEAT) if evaluating an enumerated data
point or a field within a structured data point that has an enumerated type.
Note: You cannot use a preset as the comparison value.
e. To create another condition that must evaluate to TRUE for the case to be executed (create a
nested IF-THEN statement), click the bottom level ALWAYS case and repeat steps 3–4.
Otherwise, skip to step f.
f.
Expand the bottom-level ALWAYS or IF-THEN statement to show the CASE rule.
g. Click Submit.
5. Click anywhere in the COPY rule to edit the rule.
a. Select an input point (to the left of the TO operator) from the list. If you created a nested
IF-THEN statement (two IF statements), the input point in the Copy rule is the same input
point you selected in the nested (second) IF statement, and it cannot be changed.
b. If you selected a structured data point in the ALWAYS statement, select whether to copy a
field or the entire structure to the output point. By default, the entire structure is selected.
c. Enter a multiplier (a whole or decimal number) in the multiplier box to scale the value of the
input point. The default multiplier is 1. If you are copying an enumerated value to the output
point, this box is unavailable.
d. Add or subtract a constant to the value of the input point. To do this, select the desired
operator and then enter the value of the constant in the constant box. The default constant is
1. If you are copying to an enumerated output point, select the string value (for example,
HVAC_HEAT) of an enumerated data point or field in this box. You cannot copy an index
to an enumerated output point. If you are copying to an enumerated field within a structured
data point, you must first select the enumerated field from the output point box (to the right of
the TO operator) as described in step f.
