EVENT_I
NFO
WORD I, Q, M,
D, L
When EVENT_SCHEME ≤ 4, the lower 10 bits of EVENT_INFO indicate the
event data.
When EVENT_SCHEME = 255, EVENT_INFO shows "16#0000".
For the detailed meaning of EVENT_INFO in DALI standard, refer to the
following section "Parameter EVENT_INFO".
RSV_MS
G
BOOL I, Q, M,
D, L
The status of the reserved message. When the CM 1xDALI receives a re-
served message, the RSV_MSG remains true for one cycle:
• RSV_MSG = 0: No reserved message
• RSV_MSG = 1: A reserved message is received.
RSV_MS
G_LEN
USInt I, Q, M,
D, L
The bit length of the reserved message
RSV_MS
G_VAL
DWORD I, Q, M,
D, L
The bit stream of the reserved message
1
For a valid device group, group of EVENT_SRC_1 indicates the lowest group; otherwise it shows "16#FF".
2
For a valid short address, short address of EVENT_SRC_2 indicates the short address of the device; oth-
erwise, it shows "16#FF".
Parameter CM_STATUS
Each Bit of the CM_STATUS indicates the different status:
Bit
Explanation of status
Bit 0
The CM 1xDALI is initializing.
