DALI_ECG_QUERY_EXT_PARAM
Description
DALI_ECG_QUERY_EXT_PARAM
is used for querying the extended parameters of DALI
control gears.
● When you set the input "PHY_DEV" to 1, this function block queries the extended
parameters from the physical device (refer to data flow path 6 (Page 23)).
● When you set the input "PHY_DEV" to 0, this function block queries the parameters which
are saved in CM 1xDALI (refer to data flow path 2 (Page 23)).
The extended parameters have the following features:
● The extended parameters are type-related.
● The extended parameters in the physical device can only be queried from the control
gears whose type range is from 1 to 8; Otherwise, the error code “16#87” (Not supported)
is shown in the output parameter of STATUS.
● The extended parameters which are saved in CM 1xDALI can only be queried from the
control gear whose type is 1, or 4 to 8.
You can set the extended parameters of control gear by using
DALI_ECG_SET_EXT_PARAM (Page 79).
