Consider a schema having a Variable operator with module scope that references a signal named fSignal_m. Suppose the schema were linked to two modules in a hardware interface file, say "Module A" and "Module B". Since the Variable operator is of module scope, it represents a distinct signal within each module. That is, fSignal_m in "Module A" is not the same variable as fSignal_m in "Module B". As such, they can be assigned different initial values (among other attributes) in the Module Variable Settings dialog for each module.
