FB_DALI209SetSystemFailureValues

The function block writes the color representation and light intensity (nSystemFailureLevel) of the light source to be used in the case of a system failure to the DALI control gear.

	Prior to the DALI command SET SYSTEM FAILURE LEVEL, the function block sends the DALI command ENABLE DEVICE TYPE 8, as is necessary for application extended commands (see FB_DALI102EnableDeviceType) and SET TEMPORARY COLOUR TEMPERATURE TC.

	The function block changes the DTR0 and the DTR1 of all connected DALI control gears.

END_VAR

Name	Type	Description
bStart	BOOL	Execution of the DALI commands is triggered via a positive edge at this input.
nAddress	BYTE	Address of a DALI control gear or a DALI group.
eAddressType	E_DALIAddressType	Defines whether the input nAddress contains a short address (0…63) or a group address (0…15). The input nAddress has no meaning if a broadcast or a broadcast to unaddressed devices (BroadcastUnaddr) has been selected.
eCommandPriority	E_DALICommandPriority	Priority (low, middle low, middle, middle high, high) with which the DALI commands are sent.

	eCommandPriority has no function with the KL6811. The DALI command priorities are supported by the KL6821 from the firmware version BD.

Name	Type	Description
nSystemFailureLevel	USINT	Output value in the case of a system failure (0…255).
eColourType	E_DALIColourType	Defines the color setting with which the function block is operated (see colourType). MASK prevents the color representation from being changed.
nXCoordinate	UINT	Input of the x-value of the color representation according to xy color type (see X-coordinate) in the color setting Xy coordinates (see color representation).
nYCoordinate	UINT	Input of the y-value of the color representation according to xy color type (see Y-coordinate) in the color setting Xy coordinates (see color representation).
nColourTemperatureTc	UINT	Input of the desired color temperature (see colourTemperatureTc) in the setting Color temperature Tc (see color representation).
nPrimaryColourN	UINT	Input of the color representation on the corresponding output channel on the operating device in the color setting Primary color N (see color representation).
nRedDimLevel	USINT	Setting of the red dimming level (see DimLevel) in the color setting RGBWAF (see color representation).
nGreenDimLevel	USINT	Setting of the green dimming level (see DimLevel) in the color setting RGBWAF (see color representation).
nBlueDimLevel	USINT	Setting of the blue dimming level (see DimLevel) in the color setting RGBWAF (see color representation).
nWhiteDimLevel	USINT	Setting of the white dimming level (see DimLevel) in the color setting RGBWAF (see color representation).
nAmberDimLevel	USINT	Setting of the amber dimming level (see DimLevel) in the color setting RGBWAF (see color representation).
nFreeColourDimLevel	USINT	Setting of the dimming level of the freely selectable color (see DimLevel) in the color setting RGBWAF (see color representation).

Outputs

VAR_OUTPUT
  bError                  : BOOL;
  ipResultMessage         : I_TcMessage;
  bBusy                   : BOOL;
END_VAR

Name	Type	Description
bError	BOOL	This output is switched to TRUE if an error occurs during the execution. Further information about the error can be queried via the variable ipResultMessage. The output is set to FALSE again as soon as bBusy switches to TRUE.
ipResultMessage	I_TcMessage	Interface pointer (see error evaluation) that can be used to obtain detailed information about the processing of the function block (see runtime messages). The interface pointer is valid after bBusy has changed from TRUE to FALSE.
bBusy	BOOL	The output is set as soon as execution of the DALI commands has commenced. It remains active until all DALI commands have been processed.

Properties

Name	Type	Access	Initial value	Description
ipDALICommunication	I_DALICommunication	Get,Set	0	Interface Pointer to the communication block (see Transfer of the reference to the communication block).
