DALI_SENSOR_QUERY_DEV_PARAM
Description
DALI_SENSOR_QUERY_DEV_PARAM
is used for querying the device parameters of the
input device (sensor).
● When you set the input "PHY_DEV" to 1, this function block queries the 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)).
You can set the device parameters of sensor by using DALI_SENSOR_SET_DEV_PARAM
(Page 93).
