FB_DALIV2QueryHIDFeatures 2:

This command belongs 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.

Name

Type

Description

bBusy

BOOL

When the function block is activated the output is set, and it remains active until execution of the command has been completed.

bError

BOOL

This output is switched to TRUE as soon as an error occurs during the execution of a command. The command-specific error code is contained in nErrorId. Is reset to FALSE by the execution of a command at the inputs.

nErrorId

UDINT

Contains the command-specific error code of the most recently executed command. Is reset to 0 by the execution of a command at the inputs (see error codes).

nHIDFeatures

BYTE

Content of the variable (see HID FEATURES)
