"Number of records" determines the number of data sets required in the response telegram.
Example of request telegram
Here, an example telegram is provided to show read-out of the "Day Profile Memory" of the
device with the "Data Identifier" 0x6D, OID "0x00002CE2", and number of data sets "0x02".
Table 6- 20 Example of request telegram
1 byte 1 byte 5 bytes
Data log identifier (day profile memory) Data identifier (all channels energy) Advanced data identifier (4 byte OID
and 1 byte number of records.)
0x04 0x6D 0x00002CE2 0x02
Table 6- 21 Example of response telegram
04 Data log identifier -> day profile memory
6D Data identifier -> channels 1 + 2 (active energy) and readings of energy counters T1+T2
00 00 2C E2 Set the read pointer to OID 0x00002CE2 of the day profile memory
02 Number of records inserted in this telegram (may be smaller than requested)
