Data Record Header (DRH)
Each data record consists of a Data Record Header (DRH) and the value (data). The DRH consists of a Data Information Block (DIB) and a Value Information Block (VIB). The DIB specifies the length, type and coding of the data. The VIB specifies the unit for the data and the multiplier to use. NOTE An application message can contain either just a single data record but also an arbitrary number of such data records in arbitrary order, each describing and containing a data element. For examples of such multi record messages see FprCEN/TR 17167:2017, Annex A, or for further information on M-Bus see FprCEN/TR 17167:2017, Annex C. 6.3 Data Information Block (DIB) 6.3.1 General The DIB contains at least one byte of Data Information Field (DIF), and can be extended by a maximum of 10 Data Information Field Extensions (DIFE). 6.3.2 Data Information Field (DIF) The coding of the DIF is shown in Table 3. Table 3 — Data Information Field (DIF) Bit 7 6 5 4 3 2 1 0 Extension bit (E) LSBit of storage number Function field Data field: Length and coding of data 6.3.3 Data field The data field shows how length and coding of data shall be interpreted. Table 4 shows the allowed codes for the data field. SIST EN 13757-3:2018

a If a wireless M-Bus data container is used it counts the number of bytes inside the container (see also Table 12, Footnote f). All multi byte fields following LVAR (according Table 5) shall be transmitted with Least Significant Byte first. A Code of 1111b implies coding for special functions as specified in Table 6. Table 6 — DIF-coding for special functions DIF Function 0Fh Start of manufacturer specific data structures to end of user data (see 6.5) 1Fh Same meaning as DIF = 0Fh + more records follow in next datagram (see 6.5) 2Fh Idle filler (not to be interpreted), following byte = DIF of next record 3Fh to 6Fh Reserved 7Fh Global readout request (all storage numbers, units, tariffs, function fields) 6.3.4 Function field The Function Field gives the type of value as specified in Table 7. Table 7 — Function field Code Description 00b Instantaneous value 01b Maximum value 10b Minimum value 11b Value during error state 6.3.5 Storage number Bit 6 of the DIF serves as the LSBit of the storage number of the data concerned, and the slave can in this way indicate and transmit various stored metering values or historical values of metering data.
