Slave Data Request
| Byte Index | 0 | 1 | 2... |
|---|
| Field | Protocol | ReqID | Payload |
- Protocol:
- 0: Slave Mode Meters & More – PLC (DSAP = 0x00)
- 4: Slave Mode Meters & More - F mode / PLC (DSAP = 0x03)
- 6: Slave Mode Meters & More – F mode / PLC (DSAP = 0x01)
- ReqID should be the same as the corresponding Slave_Data_Indication request
ID.
- Payload data for Slave Mode corresponds to the DATA field of the LLC sub layer
and to the APPLICATION LAYER (RESPONSE) information without crc32, that will be
calculated and added by module
Slave Negative Confirm
| Byte Index | 0 |
|---|
| Field | Error Code |
- Error Code: BUSY, WPV, ERROR
Slave Indication
| Byte Index | 0 | 1 | 2... |
|---|
| Field | Protocol | ReqID | Payload |
- Protocol:
- 0: Slave Mode Meters & More – PLC (DSAP = 0x00)
- 4: Slave Mode Meters & More - F mode / PLC (DSAP = 0x03)
- 6: Slave Mode Meters & More – F mode / PLC (DSAP = 0x01)
- The EUT shall generate a progressive number (1-255).
- Payload data corresponds to the DATA field of the LLC sub layer and
correspond to the APPLICATION LAYER (REQUEST) information
Note: Protocol values are extended for encrypted/authenticated
frames, according to Host Interface specification. However, the current version does
not use this extension and relies only in SSAP and ATTR fields of frame.
Master Data Request
| Byte Index | 0 | 1 | 2 ... |
|---|
| Field | Protocol | ReqID | Payload |
- Protocol:
- 1: Master Mode Meters & More – PLC (DSAP = 0x00)
- 2: Master Mode Meters & More – PLC Network Management (DSAP =
0x02)
- Master Requests the host should use a unique Request ID for each request (a
progressive number?) 0x00 is reserved (not to be used)
- Payload:
| Byte Index | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8...(len 0 - 42) | 8 + (0 - 42) | 9 + (0 - 42) | 10 + (0 - 42) | 11 .... |

| Field | LT | ADDRESS | CTL | RP | Reserved | INF-control | INF-LSAP | INF-Data |
See MAC Frame Specification for a detailed description of fields.
Note: Protocol values are extended for encrypted/authenticated
