Slave Data Request
| Byte Index | 0 | 1 | 2... |
|---|
| Field | Protocol | ReqID | Payload |
- Protocol:
- 0: Slave mode Meters And
More – PLC (DSAP = 0x00)
- 4: Slave mode Meters And
More – F mode / PLC (DSAP = 0x03)
- 6: Slave mode Meters And
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
And More – PLC (DSAP = 0x00)
- 4: Slave mode Meters
And More – F mode / PLC (DSAP = 0x03)
- 6: Slave mode Meters
And 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
And More – PLC (DSAP = 0x00)
- 2: Master mode Meters
And 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.
