Discharge lamps function blocks

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 FB_DALIV2EnableDeviceType() function block to specify which type of control gears (emergency lighting, discharge lamps, ...) should react to the extension 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.

The variable STORED HID FAILURE

Discharge lamps function blocks 2:

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(). From version 2.6.0 of the libraries TcDALIV2 and TcDALIV2AppExtCmds, however, the Enable Device Type 2 command is internally placed automatically before all application extended commands for DALI discharge lamps.
