Part 202 (emergency lighting)

The function blocks and variables for emergency lighting supply units 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 function block FB_DALIV2EnableDeviceType to specify which type of control gears (emergency lighting, discharge lamps, ...) should respond to these commands. A detailed description of the individual DALI commands and the variables for emergency lighting supply units can be found in Part 202 of the IEC 62386 standard.

Part 202 (emergency lighting) 1:

Name	Description
FB_DALIV2Inhibit	Prevents the control gear from switching to emergency mode for 15 minutes.
FB_DALIV2QueryBatteryCharge	The variable BATTERY CHARGE (state of battery charge) is read from the control gear.
FB_DALIV2QueryDurationTestResult	The variable DURATION TEST RESULT is read from the control gear.
FB_DALIV2QueryEmergencyLevel	The variable EMERGENCY LEVEL (emergency illuminance) is read from the control gear.
FB_DALIV2QueryEmergencyMaxLevel	The variable EMERGENCY MAX LEVEL (maximum emergency illuminance) is read from the control gear.
FB_DALIV2QueryEmergencyMinLevel	The variable EMERGENCY MIN LEVEL (minimum emergency illuminance) is read from the control gear.
FB_DALIV2QueryEmergencyMode	The variable EMERGENCY MODE is read from the control gear.
FB_DALIV2QueryEmergencyStatus	The variable EMERGENCY STATUS is read from the control gear.
FB_DALIV2QueryFailureStatus	The variable FAILURE STATUS is read from the control gear.
FB_DALIV2QueryFeatures	The variable FEATURES is read from the control gear.
FB_DALIV2QueryLampEmergencyTime	The variable LAMP EMERGENCY TIME is read from the control gear.
FB_DALIV2QueryLampTotalOperationTime	The variable LAMP TOTAL OPERATION TIME is read from the control gear.
FB_DALIV2QueryRatedDuration	The variable RATED DURATION is read from the control gear.
FB_DALIV2QueryTestTiming	Depending on the content of the DTR (data transfer register) the variables FUNCTION TEST DELAY TIME, DURATION TEST DELAY TIME, FUNCTION TEST INTERVAL, DURATION TEST INTERVAL, TEST EXECUTION TIMEOUT or PROLONG TIME are read from the control gear.
FB_DALIV2ReLightResetInhibit	The control gear is switched back to emergency mode (in the absence of mains voltage).
FB_DALIV2ResetDurationTestDoneFlag	The 'Duration test completed and result is valid' flag is reset.
FB_DALIV2ResetFunctionTestDoneFlag	The 'Function test completed and result is valid' flag is reset.
FB_DALIV2ResetLampTime	The variables LAMP EMERGENCY TIME und LAMP TOTAL OPERATION TIME are reset.
FB_DALIV2Rest	Switches the lamp off when emergency mode is active.
FB_DALIV2StartDurationTest	Starts the duration test.
FB_DALIV2StartFunctionTest	Starts the function test.
FB_DALIV2StopTest	Stops any type of function test or duration test.
FB_DALIV2StoreDTRAsDurationTestInterval	Writes the value of the DTR (data transfer register) into the variable DURATION TEST INTERVAL.
FB_DALIV2StoreDTRAsEmergencyLevel	Writes the value of the DTR (data transfer register) into the variable EMERGENCY LEVEL.
FB_DALIV2StoreDTRAsFunctionTestInterval	Writes the value of the DTR (data transfer register) into the variable FUNCTION TEST INTERVAL.
FB_DALIV2StoreDTRAsProlongTime	Writes the value of the DTR (data transfer register) into the variable PROLONG TIME.
FB_DALIV2StoreDTRAsTestDelayTimeHighByte	Writes the value of the DTR (data transfer register) into the high-order byte of variable TEST DELAY TIME.
FB_DALIV2StoreDTRAsTestDelayTimeLowByte	Writes the value of the DTR (data transfer register) into the low-order byte of the variable TEST DELAY TIME.
FB_DALIV2StoreDTRAsTestExecutionTimeout	Writes the value of the DTR (data transfer register) into the variable TEST EXECUTION TIMEOUT.

	These commands belong to the application extended commands for DALI emergency lighting. These only work if they are preceded by the Enable Device Type 1 command, which can be sent with the function block FB_DALIV2EnableDeviceType. The Enable Device Type 1 command is internally placed automatically before all application extended commands for DALI emergency lighting.
