Alias resolution in class-based modules occurs in the controller.
When alias properties change, the module using the alias does not have to be downloaded to pick up the new values
Aliases in class-based modules resolve in top and composite levels.
Alias replacement occurs for all external reference parameters at the top level of a module and at lower levels of a module.
Alias replacement occurs for all CALC/LOGIC expressions at the module level and lower levels.
Alias replacement occurs for all SFC expressions at the module level and lower levels.
When using a class-based module's alias' IGNORE field, the correct syntax is the '//^ notation. For example:
'PARAM1.CV' != '//^ALIAS1.IGN'
This differs from the syntax used in unit modules and their unit phases.
