1 CPU sends data to CM 1xDALI, and CM 1xDALI stores the data. For example, the CPU uses
DALI_ECG_SET_OPHOUR (Page 59) to set the operating hour of control gear in CM 1xDALI.
2 CPU receives data from CM 1xDALI. For example, the CPU uses
(Page 37) to obtain the
address status and device status which are saved in CM 1xDALI.
3 CM 1xDALI sends data to the DALI device. For example, the CPU uses
(Page 102) to deploy
the configuration parameters stored in the CM 1xDALI to the DALI device.
4 CM 1xDALI receives data from the DALI device, and stores the data in CM 1xDALI. For example, the CM 1xDALI que-
ries the device status of each DALI device by background detection.
5 CPU sends data to the DALI device. For example, the CPU uses
DALI_SENSOR_SET_INST_PARAM
(Page 97) to
send the instance configuration parameters to the DALI device
6 CPU receives data from DALI device. For example, the CPU uses
(Page 52) to query the global
trade item number from the DALI device.
