1.3.3 Packet Header
The packet header contains the first 6 bytes of the packet when
1-byte logical addressing is used. When 8-byte physical
addressing is used, the source and destination addresses each
contain 8 bytes. In this case, the header can consist of a
maximum of 20 bytes. Unused fields marked RSVD are for future
expansion and are transmitted as bit 0.
PLT packet header fields in detail.

1.3.4 Payload
The packet payload has a length of 0 to 31 bytes. Payload
content is user defined and can be read or written through I
1.3.5 Packet CRC
The last byte of the packet is an 8-bit CRC value used to check
packet data integrity. This CRC calculation includes the header
and payload portions of the packet and is in addition to the
powerline packet header CRC.
1.3.6 Sequence Numbering
The sequence number is increased for every new unique packet
transmitted. If in acknowledged mode and an acknowledgment
is not received for a given packet, that packet will be re-trans-
mitted (if TX_Retry > 0) with the same sequence number. If in
unacknowledged mode, the packet will be transmitted (TX_Retry
+ 1) times with the same sequence number.
If the receiver receives consecutive packets from the same
source address with the same sequence number and packet
CRC, it does not notify the host of the reception of the duplicate
packet. If in acknowledged mode, it still sends an acknowl-
edgment so that the transmitter knows that the packet was
received.
1.3.7 Addressing
The CY8CLED16P01 has three modes of addressing:

Logical addressing: Every CY8CLED16P01 node can have
either a 8-bit logical address or a 16-bit logical address. The
logical address of the PLC Node is set by the local application
or by a remote node on the Powerline.

1.3.8 Group Membership
Group membership enables the user to multicast messages to
select groups. The CY8CLED16P01 supports two types of group
addressing:
■
■
Both of these membership modes can also be used together for
group membership. For example, a single PLC node can be a
part of Group 131 and also multiple groups such as Group 3,
Group 4, and Group 7.
The group membership ID for broadcasting messages to all
nodes in the network is 0x00.
The service type is always set to Unacknowledgment Mode in
Group Addressing Mode. This is to avoid acknowledgment
flooding on the powerline during multicast.
1.3.9 Remote Commands
In addition to sending normal data over the Powerline, the
CY8CPLC10 can also send (and request) control information to
(and from) another node on the network. The type of remote
command to transmit is set by the TX_CommandID register and
when received, is stored in the RX_CommandID register.
When a control command (Command ID = 0x01 - 0x08 and 0x0C
- 0x0F) is received, the protocol will automatically process the
packet (if Lock_Configuration is '0'), respond to the initiator, and
notify the host of the successful transmission and reception.
When the send data command (ID 0x09) or request for data
command (ID 0x0A) is received, the protocol will reply with an
acknowledgment packet (if TX_Service_Type = '1'), and notify
the host of the new received data. If the initiator doesn't receive
the acknowledgment packet within 500ms, it will notify the host
of the no acknowledgment received condition.
When a response command (ID 0x0B) is received by the initiator
within 1.5s of sending the request for data command, the
protocol will notify the host of the successful transmission and
reception. If the response command is not received by the
initiator within 1.5s, it will notify the host of the no response
received condition.
The host is notified by updating the appropriate values in the
INT_Status register (including Status_Value_Change).
The command IDs 0x30-0xff can be used for custom commands
that would be processed by the external host (e.g. set an LED
color, get a temperature/voltage reading). The available remote
commands are described in
respective Command IDs.
Physical addressing: Every CY8CLED16P01 has a unique
64-bit physical address.
Group addressing: This is explained in the next section.
Single Group Membership – The network protocol supports up
to 256 different groups on the network in this mode. In this
mode, each PLC node can only be part of a single group. For
example, multiple PLC nodes can be part of Group 131.
Multiple Group Membership – The network protocol supports
eight different groups in this mode and each PLC node can be
a part of multiple groups. For example, a single PLC node can
be a part of Group 3, Group 4, and Group 7 at the same time.
