The function property command service is used by a common external message interface (cEMI) client to send a function property command request frame,
M_FuncPropCommand.req
. It must be followed by a function property command confirmation frame,
M_FuncPropCommand.con
, sent by a cEMI server. The confirmation indicates whether the request was successful.

Creates and returns a device management function property command confirmation frame with the return code set to code and the data field to data .
The available default argument request can be used to fill some of the returned frame fields instead of using the setter functions provided.
The common way to create such a confirmation is:
void MyCemiServer::slotFrameReceived(const QKnxDeviceManagementFrame &request) { // do some work auto data = ... auto confirmation = QKnxDeviceManagementFrame::functionPropertyCommandBuilder() .createConfirmation(QKnxNetIpCemiServer::ReturnCode::NoError, data, request); deviceManagement.sendFrame(confirmation); }
注意： The returned frame may be invalid depending on the values used during setup.

Creates and returns a negative device management function property command confirmation frame.
The available default argument request can be used to fill some of the returned frame fields instead of using the setter functions provided.
The common way to create such a confirmation is:
void MyCemiServer::slotFrameReceived(const QKnxDeviceManagementFrame &request) { // do some work bool error = ... if (error) { auto confirmation = QKnxDeviceManagementFrame::functionPropertyCommandBuilder() .createNegativeConfirmation(request); deviceManagement.sendFrame(confirmation); } }
注意： The returned frame may be invalid depending on the values used during setup.
