3.3.6 Check input device status
Description
This command checks the input device status stored in the CM 1xDALI, compare
them with the input status filters, and return the matching results
1
.
Command ID
16
Input Param-
eters
Byte 0 to 63 Status filters for all short addresses: for example, Byte 0 is for the
device with address 0; Byte 1 is for the device with address 1.
Response
Parameters
Byte 0
Return code (Page 51)
Byte 1 to 8 Matched flag for all devices. If a logical AND of the input device status
and the input status filter is not 0, this instruction sets the match flag.
Each bit indicates the status for one device: for example, Bit 0 of Byte
1 indicates the device with address 0; Bit 1 of Byte 1 indicates the
device with address 1; Bit 0 of Byte 2 indicates the device with ad-
dress 8.

Example
:
For the input device whose short address is 4, if you want to check whether bit 0 of the
device status is set to 1, you should set the input parameters as:
16#00 16#00 16#00
16#00 16#01 16#00 16#00 16#00
16#00 16#00 16#00 16#00 16#00 16#00 16#00 16#00
16#0
0 16#00 16#00 16#00 16#00 16#00 16#00 16#00
16#00 16#00 16#00 16#00 16#00 16#00 16#00 16#00
16#00 16#00 16#00 16#00 16#00 16#00 16#00 16#00

16#00 16#00 16#00 16
#00 16#00 16#00 16#00 16#00
If the bit 0 of the device status is set to 1, you will get the response parameters as:
16#00 16#10 16#00 16#00 16#00 16#00 16#00 16#00 16#00
