Abbreviations Acronyms Definition Power Meter One phase Smart meter and three phase Smart meter CCO module CCO module is placed into concentrator. It included 3 QCA6411, 1 5-ports-switch. STA module STA module is placed into smart meter. It included 1 QCA7000. CCO Central Coordinator STA Station NSTA Normal STA PSTA Proxy STA HSTA Hidden STA AVLN HomePlug AV Logical Network Relay CCO cannot communicate with 1 HSTA, but via PSTA with relay, it can communicate with each other. n Relay MME Multi- relay MAC Management Message PB PHY Block TEI Terminal Equipment Identifier QCA6411 Lynx chip used for CCO QCA7000 Lynx chip used for STA DA Destination Address，Destination MAC address SA Source Address，Source MAC address。 Table 1-1：Acronyms and Abbreviations page 5 QCA-PLC-SG-firmware-application-notes v1.0.0 page 6 2 Architecture Overview 2.1 Power line Frequency To comply with the HomePlug GP specification, the Powerline frequency must be 50Hz±3.0% or 60 Hz±3.5%. Powerline frequency outside of this range will cause the firmware to reboot the device. 2.2 SG System architecture Figure 2-1：QCA broadband PLC Smart Grid system block diagram CCO module was plugged into concentrator, which had 3 QCA6411 corresponding to 3 phase power line, per QCA6411 use different Network password to indicate 3 different AVLAN. Per VLAN support 253 STAs. STA module was plugged into power meter, which deployed with 1 QCA7000.STA module fetch power meter data via UART @2400 baud rate. UART baud rate can be configured with AVITAR tools.(@1200 @9600 not recommend to use high baud rate) 3 QCA6411 connect with switch and communicate with concentrator via Ethernet port. QCA-PLC-SG-firmware-application-notes v1.0.0 page 7 3 UART Data transparent TX/RX 3.1 UART Data transmit Payload was raw UART data user wants to send to power meter. Maxim UART data length is within 256 Bytes. This transmit is initiated by Concentrator, so user need to fill in MME packet, refer chapter 4 for sending MME Data. UART data will transparently send to power meter, so the UART data should be valid and can be recognized by power meter. Here Payload is UART RAW data. Figure 3-1：UART data transparently transmit QCA-PLC-SG-firmware-application-notes v1.0.0 page 8 3.2 UART Data receive Payload was raw UART data which power meter response. Maxim UART data length is within 256 Bytes. UART data will be sent to concentrator transparently. Received MME packet, concentrator can recognize which STA Module response. Further UART data analysis will be handled by concentrator. Figure 3-2：UART data transparently receive 3.3 Power Meter Address and MAC address Mapping Per STA module has own mac address (QCA7000 MAC Address), which was stored in NVM. This mac address can be configured by AVITAR tools. The mapping relationship between QCA7000 module MAC address and Meter ID should be maintained by Concentrator program. Power meter address and mac address mapping can be realized by following steps: 1. Concentrator sends VS_NW_INFO_STATS_Req MME to fetch how many STA modules are online. 2. Concentrator initially sends unicast MME frame to online STA module. Payload (UART Data) should be data to fetch the power meter address or other packet which power meter can recognize. 3. Concentrator analysis the received payload, and extract the power meter ID. 4. Maintain the mapping with STA module MAC address with power meter ID. QCA-PLC-SG-firmware-application-notes v1.0.0 4 Communication protocol 4.1 Protocol Concentrator communicates with CCO Module via MME. CCO communicate with remote server via private protocol, such as 372.1 etc. CCO Module communicates with STA Module via HomePlugAV protocol. The user just focus on protocol (MME) between Concentrator with CCO module, low level communication is invisible to user. 4.2 Ethernet MME packet header Offset 0x0000 0x0006 0x000C 0x000E 0x000F 0x0011 Size 6 6 2 1 2 3 Field Name ODA OSA MTYPE MMV MMTYPE OUI Description Original Destination Address Original Source Address Ethertype (0x88, 0xE1) MME Version (0) MME Type Intellon OUI (0x00, 0xb0, 0x52) Table 4-1：MME Packet Header Different Ethernet MME is raw mac frame which shared same packet heard, refer table 4-1. 4.3 Get power meter data request (VS_UART_CMD_Req MME) Offset 0x0000 0x0006 0x000C 0x000E 0x000F 0x0011 0x0014 0x0016 Size 6 6 2 1 2 3 2 Variable Field Name ODA OSA MTYPE MMV MMTYPE OUI LENGTH DATA Description Original Destination Address Original Source Address Ethertype (0x88, 0xE1) MME Version (0) 0xA400 (Request) Intellon OUI (0x00, 0xb0, 0x52) UART raw data length UART raw data Table 4-2：VS_UART_CMD_Req ODA: OSA: MTYPE: MMV: MMTYPE: OUI: LENGTH: DATA: STA module mac address Concentrator mac address 0x88, 0xE1 (constant ) 0 (constant ) 0xA400(constant ) 0x00, 0xB0, 0x52(constant ) Length of DATA, size in bytes UART command(raw data) page 9 QCA-PLC-SG-firmware-application-notes v1.0.0 page 10 Use wire shark tools to monitor the data you send, the captured data should be like Figure 5-1.

In order to get the topology of CCo, App should follow below steps: 1. Send a get tree command to CCo, “root MAC” is CCo’s MAC 2. CCo will return the list of STAs directly connected to it. 3. App check each STA’s info, if any STA has at least one STA under it (numOfSTA is non-zero in Error! Reference source not found.), App should send a similar get tree command to CCo with “root MAC” set to STA’s mac instead. (NOTE: STAs having other STA under it are the non-leaf node in the tree topology, STAs not having other STA under it are the leaf node in the tree topology) 4. Loop 3 until complete sending request MME to CCo for querying all the non-leaf STA (loop all the non-leaf STAs by sending a get tree command) 5. App construct the tree topology based on the information above and show it out. To get the data path (relay path) for a STA, App should follow below steps: 1. Send a trace command to CCo, “root MAC” is the STA’s MAC 2. CCo will return a response with the STA list where all STAs on the path between STA and CCo are listed. 3. App show it out.

If FIRST_TEI is Zero the NUMSTAS field will be valid and up to 96 sets of Station Information will be returned. Otherwise the NUMSTAS field will list the number of sets of Station Information returned and all the existent sets of Station Information will be return at or after the FIRST_TEI (up to 96). Table 4-9： VS_NW_INFO_STATS_Req This MME is sent by concentrator to get the network information, which devices registered in the network, and get the MAC address of each device, if some expected devices not exist in the network, concentrator cannot communicate with these devices. Notes: If FIRST_TEI is set to 0, NUMSTAS in the response stands for total stations in the network, if the number is bigger than 96, users should send the second or maybe third request to get the information(max station number in a network is 253), since the max size of Ethernet frame is 1514 octets. The first request, FIRST_TEI = 0, The second request, FIRST_TEI = 98, The third request, FIRST_TEI = 194, Station TEI starts from 2, the MAX TEI is 254.
