FB_DALI209StoreGearFeaturesStatus

The function block saves the value nGearFeaturesStatus in the variable gearFeatures/Status of the DALI control gear.

The value can be read with the function block FB_DALI209QueryGearFeaturesStatus.

If Bit 0 is set to 1, all commands for controlling the lamp power – with the exception of ENABLE DAPC SEQUENCE – automatically initiate a color transition.

	Prior to the DALI command STORE GEAR FEATURES/STATUS, the function block sends the DALI command ENABLE DEVICE TYPE 8, as is necessary for application extended commands (see also FB_DALI102EnableDeviceType).

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

	The function block sends the DALI command STORE GEAR FEATURES/STATUS twice, as foreseen by the DALI standard for certain DALI commands.

Inputs

VAR_INPUT
  bStart                    : BOOL;
  nAddress                  : BYTE;
  eAddressType              : E_DALIAddressType := E_DALIAddressType.Short
  eCommandPriority          : E_DALICommandPriority := E_DALICommandPriority.MiddleLow;
  nGearFeaturesStatus       : BYTE;
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
nGearFeaturesStatus	BYTE	Value written to the variable gearFeatures/Status.

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).
