Each case rule is defined by a element. The following table describes the properties that
should be filled in within each element to define each case rule.
Property Description
The index number of the case rule.
NOTE: If more than one case rule attempts to assign a value to the
same data point or data point field, the case rule listed last in the
XML file (i.e. the one with the highest index number) takes
precedence.
A reference to the property of the input data
point. The value of this data point will be compared to the
selected for the case rule using the
comparison function defined by the
property.
If the result of the comparison is True, the case rule will modify the
value of the input data point using the operations determined by the
and properties, and assign the
resulting value to the output data point specified in the
property.
If the input point has a structured data type and you need to
evaluate a field within the structure, you need to specify that field
in this property.
You do not need to specify this property if you are evaluating a
scalar data point or a structured data point as a whole.
A reference to the property of the output data
point in which the value calculated by this case rule is to be stored.
If the output point has a structured data type and you are writing to
a field within the structure, you need to specify that field in this
property.
You do not need to specify this property if you are writing to a
scalar data point or a structured data point as a whole.
If you are evaluating a data point in the case rule, specify the
and properties.
If you are not evaluating a data point in the rule, specify FN_NUL
for . You do not need to specify a
property in this case.
The selected must use the same value format
