Part 207 (LED modules)

Function blocks

The function blocks and variables for LED modules with DALI interface are described below. All below function blocks described below call 'application-related expansion 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-related expansion 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 checks 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-specific expansion commands for LED modules with DALI interface. They function only if they are preceded by the Enable Device Type 6 command, which can be sent with the FB_DALIV2EnableDeviceType() function block. The command Enable Device Type 6 is already automatically internally prefixed to all application-related expansion commands for LED modules with DALI interface.
