The Calculator adapter supports undeclared parameters.
Any parameter name used in the calculation is created as a parameter
when you click Calculate, Apply,
or Ok. Automation Process
Composer attempts to determine the correct mode (input, output, in/out, or local)
of the parameter, data type (real, integer, or string), and structure
based on how the parameter is used. If
there is insufficient information to determine the data type and structure,
Automation Process
Composer creates a real scalar parameter.
When you click Ok to close the Calculator
Editor, each parameter’s mode is updated to reflect
how the parameter is used in the calculation as follows:
-
If the parameter is assigned, the mode becomes output.
-
If the parameter is referenced, the mode becomes input.
-
If the parameter is referenced and then assigned, the mode becomes In/Out.
Automation Process
Composer follows these rules to ensure that existing parameter mappings are not
broken.
