The Device Identification interface is modeled as an address space composed of a set of addressable data elements. The data elements are called objects and an \l ObjectId identifies them. */ /*! \enum QModbusDeviceIdentification::ObjectId This enum describes the possible server objects. The interface consists of three categories of objects: Basic Device Identification. All objects of this category are mandatory. \value VendorNameObjectId The vendor name of the device. \value ProductCodeObjectId The product code of the device. \value MajorMinorRevisionObjectId The product version numbering. Regular Device Identification. All objects of this category are standard defined and optional. \value VendorUrlObjectId The vendor URL of the device. \value ProductNameObjectId The product name of the device. \value ModelNameObjectId The model name of the device. \value UserApplicationNameObjectId The user application name of the device. Reserved range (i.e., ReservedObjectId >= ObjectId < ProductDependentObjectId). Do not use. \value ReservedObjectId First value of reserved object Ids. Extended Device Identification. All of these data are device dependent and optional. \value ProductDependentObjectId First possible value of product dependent identifiers. \value UndefinedObjectId Do not use. */ /*! \enum QModbusDeviceIdentification::ReadDeviceIdCode Defines the access type of the read identification request. Stream access: \value BasicReadDeviceIdCode Request to get the basic device identification. \value RegularReadDeviceIdCode Request to get the regular device identification. \value ExtendedReadDeviceIdCode Request to get the extended device identification. Individual access: \value IndividualReadDeviceIdCode Request to get one specific identification object. */ /*! \enum QModbusDeviceIdentification::ConformityLevel Defines the identification conformity level of the device and type of supported access. \value BasicConformityLevel Basic identification (stream access). \value RegularConformityLevel Regular identification (stream access). \value ExtendedConformityLevel Extended identification (stream access). \value BasicIndividualConformityLevel Basic identification (stream access and individual access). \value RegularIndividualConformityLevel Regular identification (stream access and individual access). \value ExtendedIndividualConformityLevel Extended identification (stream access and individual access). \sa ReadDeviceIdCode */ /*! \fn QModbusDeviceIdentification::QModbusDeviceIdentification() Constructs an invalid QModbusDeviceIdentification object. */ /*! \fn bool QModbusDeviceIdentification::isValid() const Returns \c true if the device identification object is valid; otherwise \c false. A device identification object is considered valid if \l ProductNameObjectId, \l ProductCodeObjectId and \l MajorMinorRevisionObjectId are set to a non-empty value. Still the object can contain valid object id's and associated data. \note A default constructed device identification object is invalid. */ /*! \fn QList<int> QModbusDeviceIdentification::objectIds() const Returns a list containing all the object id's in the \c QModbusDeviceIdentification object in ascending order. \sa ObjectId */ /*! \fn void QModbusDeviceIdentification::remove(uint objectId) Removes the item for the given \a objectId. \sa ObjectId */ /*! \fn bool QModbusDeviceIdentification::contains(uint objectId) const Returns \c true if there is an item for the given \a objectId; otherwise \c false. \sa ObjectId */ /*! \fn QByteArray QModbusDeviceIdentification::value(uint objectId) const Returns the value associated with the \a objectId. If there is no item with the \a objectId, the function returns a \l{default-constructed value}. \sa ObjectId */ /*! \fn bool QModbusDeviceIdentification::insert(uint objectId, const QByteArray &value) Inserts a new item with the \a objectId and a value of \a value. If there is already an item with the \a objectId, that item's value is replaced with \a value. Returns \c true if the size of \a value is less than 245 bytes and the \a objectId is less then \l QModbusDeviceIdentification::UndefinedObjectId. \sa ObjectId */ /*! \fn ConformityLevel QModbusDeviceIdentification::conformityLevel() const Returns the identification conformity level of the device and type of supported access. */ /*! \fn void QModbusDeviceIdentification::setConformityLevel(ConformityLevel level) Sets the identification conformity level of the device and type of supported access to \a level. */ /*!
