SIST EN 13757-3:2018
EN 13757-3:2018 (E) 6 Introduction This European Standard belongs to the EN 13757 series, which covers communication systems for meters. EN 13757-1 contains generic descriptions and a communication protocol. EN 13757-2 contains a physical and a link layer for twisted pair based Meter-Bus (M-Bus). EN 13757-4 describes wireless communication (often called wireless M-Bus or wM-Bus). EN 13757-5 describes the wireless network used for repeating, relaying and routing for the different modes of EN 13757-4. EN 13757-6 describes a twisted pair local bus for short distance (Lo-Bus). EN 13757-2 describes transport mechanism and security methods for data. The Technical Report CEN/TR 17167 contains informative annexes for EN 13757-2, EN 13757-3:2018 and EN 13757-7. These upper M-Bus protocol layers can be used with various Physical Layers and with Data Link Layers and Network Layers, which support the transmission of variable length binary transparent messages. Frequently, the Physical and Link Layers of EN 13757-2 (twisted pair) and EN 13757-4 (wireless) as well as EN 13757-5 (wireless with routing function) or the alternatives described in EN 13757-1 are used. These upper M-Bus protocol layers have been optimized for minimum battery consumption of meters, especially for the case of wireless communication, to ensure long battery lifetimes of the meters. Secondly, it is optimized for minimum message length to minimize the wireless channel occupancy and hence the collision rate. Thirdly, it is optimized for minimum requirements towards the meter processor regarding requirements of RAM size, code length and computational power. An overview of communication systems for meters is given in EN 13757-1, which also contains further definitions. This standard concentrates on the meter communication. The meter communicates with one (or occasionally several) fixed or mobile communication partners which again might be part of a private or public network. These further communication systems might use the same or other application layer protocols, security, privacy, authentication, and management methods. To facilitate common communication systems for CEN-meters (e.g. gas, water, thermal energy and heat cost allocators) and for electricity meters, in this standard occasionally electricity meters are mentioned. All these references are for information only and are not standard requirements. The definition of communication standards for electricity meters (possibly by a reference to CEN standards) remains solely in the responsibility of CENELEC. NOTE 1 CEN/TR 17167:2018, Annex C specifies how parts of this standard and of EN 13757–2 and EN 13757–4 can be used to implement smart meter functionalities. Similar functionalities could also be implemented using other physical and link layers. NOTE 2 For information on installation procedures and their integration in meter management systems, see CEN/TR 17167:2018, Annex D.

Binary numbers are designated by a following “b”. Decimal numbers have no suffix. 5 Selection of an application protocol This European Standard supports several application protocols. A specific protocol shall be chosen accordingly to the selected CI-Field described in EN 13757-7:2018, 4.2. Beside the M-Bus protocol there are specific protocols described in the following clauses. Further application protocols applying DLMS/COSEM or M-Bus based usage of OBIS-type value descriptors are referenced in EN 13757-7:2018, Table 2. Annex H defines translation from M-Bus type record descriptors to OBIS-type record descriptors. The support for the different commands or protocols declared by the CI-field is optional in the meter. 6 M-Bus protocol 6.1 General The single datagram has a maximum length of 255 bytes. The data, together with information regarding coding, length and the type of data, is transmitted in data records in arbitrary sequence. According to EN 13757-2, the maximum space for data are 252 bytes. The effective usable space depends on the layers with variable length below the application layer and the applied header type and the encryption method. This restriction is required to enable gateways to other link- and application layers. The M-Bus Application Layer data may consist of two segments of data. The first segment holds M-Bus data records (see 6.2). The second, optional segment, holds manufacturer specific data. (see Table 1). Table 1 — Structure of a M-Bus APL with manufacturer specific data APL Variable data blocks (Records) MDH (optional) Manufacturer specific data (optional) Variable number 1 byte Variable number SIST EN 13757-3:2018
EN 13757-3:2018 (E) 11 A Manufacturer Data Header (MDH) shall be inserted before the manufacturer specific data. The MDH is one of the characters 0Fh or 1Fh. The MDH shall be omitted if there is no manufacturer specific data (see 6.5). Unencrypted data following encrypted data shall start at a data record boundary, i.e. the first byte of unencrypted data shall be interpreted as a DIF. Special data structures are defined in Annex F and in Annex G. If nothing other declared then multi byte fields shall be transmitted with least significant byte first (little endian). 6.2 M-Bus data record The structure of an M-Bus data record is shown in Table 2. The transmission order of the element is from left to right. Table 2 — Data record structure DIF DIFE VIF VIFE Data 1 byte 0 to 10 (1 byte each) 1 byte 0 to 10 (1 byte each) 0 to N bytes Data Information Block (DIB) Value Information Block (VIB)
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.

The coding as integer/binary by default implies coding type B (signed integer). The coding may however be overridden by the settings in VIF/VIFE of the record (e.g. date/time). Variable length: A Code of 1101b implies data with variable length. The length is coded in the first byte of the data, after the DRH and is named LVAR. (e.g. LVAR = 02h shows that two bytes of data follows.) If LVAR is used as the variable length of a wireless M-Bus data container (see FprCEN/TR 17167:2017, Annex F) it counts the number of bytes inside the container (Table 5). SIST EN 13757-3:2018
EN 13757-3:2018 (E) 13 Table 5 — LVAR interpretation Range Data Type Calculation 00h–BFha 8-bit text string according to ISO/IEC 8859-1 LVAR (0 to 191) characters C0h–C9h Positive BCD number (LVAR–C0h)*2 digits, 0 to 18 digits D0h–D9h Negative BCD number (LVAR–D0h)*2 digits, 0 to 18 digits E0h–EFh Binary number (LVAR–E0h) bytes, 0 to 15 bytes F0h–F4h Binary number 4*(LVAR–ECh) bytes, 16, 20, 24, 28, 32 bytes F5h Binary number 48 bytes F6h Binary number 64 bytes Others LVAR values Reserved
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.
