LED modules - function blocks

The function blocks and variables for LED modules with DALI interface are described below. All function blocks described below call 'application extended commands'. According to the DALI standard (IEC 62386) these commands are within the range 224 to 255. Because of the existence of a variety of application extended commands, it is necessary to use the FB_DALIV2EnableDeviceType() function block to specify which type of control gears (emergency lighting, discharge lamps, ...) should react to the extension commands. A detailed description of the individual DALI commands and the variables for LED modules with DALI interface can be found in standard IEC 62386 Part 207.

Name	Description
FB_DALIV2DisableCurrentProtector	The command disables the current protection device of the control gear.
FB_DALIV2EnableCurrentProtector	The command enables the current protection device of the control gear.
FB_DALIV2QueryCurrentProtectorActive	The system queries whether the current protection device is active.
FB_DALIV2QueryCurrentProtectorEnabled	The system queries whether the current protection device is enabled.
FB_DALIV2QueryDimmingCurve	The dimming curve of the control gear is read out.
FB_DALIV2QueryFastFadeTime	Queries the value of FAST FADE TIME.
FB_DALIV2QueryGearType	Queries the value of GEAR TYPE.
FB_DALIV2QueryLedFailureStatus	Queries the value of FAILURE STATUS.
FB_DALIV2QueryLedFeatures	Queries the value of FEATURES.
FB_DALIV2QueryLoadDecrease	The system queries whether a significant decrease in load (compared to the reference power of the system) has been detected.
FB_DALIV2QueryLoadIncrease	The system queries whether a significant increase in load (compared to the reference power of the system) has been detected.
FB_DALIV2QueryMinFastFadeTime	Queries the value of MIN FAST FADE TIME.
FB_DALIV2QueryOpenCircuit	The system queries whether an idle mode has been detected.
FB_DALIV2QueryOperatingMode	Queries the value of OPERATING MODE.
FB_DALIV2QueryPossibleOperatingModes	Queries the value of POSSIBLE OPERATING MODE.
FB_DALIV2QueryReferenceMeasurementFailed	The system queries whether a started reference measurement has failed.
FB_DALIV2QueryReferenceRunning	The system queries whether a reference measurement of the system performance is active.
FB_DALIV2QueryShortCircuit	The system queries whether a short circuit has been detected.
FB_DALIV2QueryThermalOverload	The system queries whether there is a thermal overload with reduction of the luminous flux.
FB_DALIV2QueryThermalShutDown	The system queries whether a thermal shutdown occurred.
FB_DALIV2ReferenceSystemPower	The control gear measures and stores the performance level of the system, in order to detect load increase and decrease.
FB_DALIV2SelectDimmingCurve	The dimming curve of the control gear is selected.
FB_DALIV2SetFastFadeTime	Sets the FAST FADE TIME in the control gear.

	These commands belong to the application extended commands for LED modules with DALI interface. These only work if they are preceded by the Enable Device Type 6 command, which can be sent with the function block FB_DALIV2EnableDeviceType(). From version 2.6.0 of the libraries TcDALIV2 and TcDALIV2AppExtCmds, however, the Enable Device Type 6 command is internally placed automatically before all application extended commands for LED modules with DALI interface.
