Substitutions

iFIX model type and template variable properties (mapped to tag fields based on block type selected) take input values as numerics, string constants, and substitutions, and offer placeholders for these inputs. You can use substitutions to enable assigning values at instance level for these properties.

You can insert substitutions directly into value cells by browsing. To use this feature, click on the property's cell value. A browse button displays in the value cell. Click this browse button to displays list of substitutions, click on the desired substitution to insert at the cursor position. Substitutions can also be used in expressions along with other value constants to finally evaluate to a final value substitution.

Note: You refer to parent substitutions using the special character “@” from a contained child object. The value from the parent object instance is substituted to the contained object.
