Digi XBee® 3 Zigbee® RF Module
Offset Description
16 Set to the destination endpoint on the remote
device. (0x42 arbitrarily selected).
MSB Set to the cluster ID that corresponds to the ZCL
17 command being sent. 0x0701 = Demand response
and load control cluster ID
LSB
18
MSB Set to the profile ID supported on the device. 0x0109
19 = Smart Energy profile ID.
LSB
20
21 Sets the maximum number of hops a broadcast
transmission can traverse. If set to 0, the
transmission radius will be set to the network
maximum hops value.
22 All bits must be set to 0.
Frame 23 Bitfield that defines the command type and other
control relevant information in the ZCL command. For more
information, see the ZCL specification.
Transaction 24 A sequence number used to correlate a ZCL
sequence command with a ZCL response. (The hardware
number version response will include this byte as a sequence
number in the response.) The value 0x01 was
arbitrarily selected.
25 Since the frame control "frame type" bits are 01, this
byte specifies a cluster-specific command. Command
ID 0x00 in the Demand Response and Load Control
cluster is a Load Control Event command. For more
information, see the Smart Energy specification.
The 4-byte unique identifier.
Issuer event 26
ID
Note
(0x78563412).
The event ID in this example (0x12345678) is
arbitrarily selected.
