Variables Pane

This pane contains information regarding the variables from the XML document that have been selected to be exposed to ModelCenter. This pane includes a tree view of the selected variables. Selecting a variable in the tree view populates the variable property and XPath Expression fields with the values for that variable. Initially, the only variable property that is shown is Type; additional variable properties can be shown by clicking the More Properties expansion button.

Field Description
Type The value type of the variable (double, double[], int, bool, string, file, etc).
Units The units of the variable (kilogram, inch, joules, $, etc).
Description A textual description of the variable.
Bounds The lower (left-hand field) and upper (right-hand field) bounds for the variable's value. If either is set and the variable value goes outside of those bounds, the component will error.
Enum Values The optional set of possible values for the variable. If this set is not empty, setting the variable to a value other than one included in the set will cause the component to error.
Enum Aliases The optional set of aliases for the enumerated values. These are used for display purposes in ModelCenter, where the actual value is masked by the alias value.
Format The format of the variable (General, 0.00E+00, $#,##0.00, etc).
XPath Expression The XPath expression used for selecting the appropriate XML node. This can be set to any valid XPath expression. See the XML and XPath help documentation for more information.
