DALI_SENSOR_STATUS_CHECK
Description
DALI_SENSOR_STATUS_CHECK
is used for checking the status of input device (sensor).
For the detailed status bits description, refer to DEV_STATUS in DALI_SENSOR_STATUS
(Page 60).
You can set the status mask of all the sensors, compare with the actual status that is stored
in the CM 1xDALI, and then return the matching result. The function block checks the status
information which is saved in the CM 1xDALI (refer to data flow path 2 (Page 23)). The CM
1xDALI queries the actual device status in the "Background detection period" which is set in
the Module Parameters (Page 21).
For example, for the sensor whose short address is 4, if you want to check whether the bit 0
of DEV_STATUS in DALI_SENSOR_STATUS (Page 60) is set to 1, you can set input
STATUS_MASK[4] to 16#01.
