Slave Data Request

Byte Index012...
FieldProtocolReqIDPayload
  • 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

FieldProtocolReqIDPayload
  • 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 Index012 ...
FieldProtocolReqIDPayload
  • 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 Index012 345678...(len 0 - 42)8 + (0 - 42)9 + (0 - 42)10 + (0 - 42)11 ....
