Part 203 (discharge lamps)
The function blocks and variables for discharge lamps 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 precise description of the individual DALI commands and the variables for discharge lamps with DALI interface will be found in Part 203 of the IEC 62386 standard. |

Function blocks
Name | Description |
|---|---|
The variable ACTUAL HID FAILURE (current failure status) is read from the control gear. | |
The variable HID FEATURES (performance characteristics) is read from the control gear. | |
The variable HID STATUS is read from the control gear. | |
The variable STORED HID FAILURE (stored failure status) is read from the control gear. | |
The variable THERMAL LOAD is read. | |
The 16-bit variable THERMAL OVERLOAD TIME is read. | |
The high-order byte of the 16-bit variable THERMAL OVERLOAD TIME is read. | |
The low-order byte of the 16-bit variable THERMAL OVERLOAD TIME is read. | |
The variable STORED HID FAILURE (stored lamp faults) is reset. |
 | These commands belong to the application extended commands for DALI discharge lamps. These only work if they are preceded by the Enable Device Type 2 command, which can be sent with the function block FB_DALIV2EnableDeviceType. The Enable Device Type 2 command is internally placed automatically before all application extended commands for DALI discharge lamps. |
