 * - ModuleLogicalName.FunctionLogicalName

 *
 * This function does not require that the 4-20mA output is online at the time
 * it is invoked. The returned object is nevertheless valid.
 * Use the method YCurrentLoopOutput.isOnline() to test if the 4-20mA output is
 * indeed online at a given time. In case of ambiguity when looking for
 * a 4-20mA output by logical name, no error is notified: the first instance
 * found is returned. The search is performed first by hardware name,
 * then by logical name.
 *
 * If a call to this object's is_online() method returns FALSE although
 * you are certain that the matching device is plugged, make sure that you did
 * call registerHub() at application initialization time.
 *
 * @param func : a string that uniquely characterizes the 4-20mA output, for instance
