Part 1 contains generic descriptions and a communication protocol. Part 2 contains a physical and a link layer for twisted pair base band (M-Bus). Part 4 (currently an enquiry is under preparation) describes wireless communication. The bus communication system of EN 14343 is commonly called M-Bus. Its application layer describes a standard especially for meter readout. It can be used with various physical layers and with link layers and network layers which support the transmission of variable length binary transparent telegrams. Frequently the physical and link layers of EN 13757-2 (Twisted pair baseband) and prEN 13757-4 (wireless) or the alternatives described in EN 13757-1 are used. An overview of communication systems for meters is given in EN 13757-1, which also contains further definitions. This standard is a compatible enhancement of the 6.4 to 6.6 of the original standard EN 14343:1997. Besides some clarifications and implementation hints it contains optional enhancements especially for complex meters. Due to technical progress some variants (Fixed format and mode 2=high byte first) are no longer supported in this standard. It should be noted that this standard contains only directions how data should be coded. It is beyond the task of an application layer standard to define which data will be transmitted under what conditions by which types of slaves or which data transmitted to a slave will have which reactions. Therefore adherence to this standard guarantees the coexistence and common communication and readout capability of slaves via a universal master software (covering all optional features), but not yet functional or communication interchangeabilty of meters following this standard. For several meter types and meter classes a group of remote heating users have provided such application descriptions required for full interchangeability. They are accessible via the www-server of the m-bus users group http:/www.m-bus.com/files/default.html (file name: WG4N99R4.EXE (this is a self expanding .doc-file).

The length information is part of the link layer. It shall be known to the application layer in order to properly terminate its decoding of each telegram. Each telegram starts with a one byte CI (control information) field, which distinguishes between various telegram types and application functions. It is also used to distinguish between true application layer communication and management commands for lower layers. The meaning of the remaining bytes of the telegram depends also on the value of the CI-field.

Note also that even if the functions of these optional CI-codes are not implemented in a slave the link layer protocol requires a proper link layer acknowledge of SND_UD telegrams containing any of these CI-codes. The EN 14343 defined two possible data sequences in multibyte records. This standard supports only the mode where the least significant byte of a multibyte record is transmitted first.

Each slave himself decides which parameters to change e.g. which data output is default after it has received such an application reset. 4.2.2 Application reset subcode (optional) It is allowed to use optional parameters after CI = 50h. If more bytes follow, the first byte is the application reset subcode. Further bytes are ignored. The application reset subcode defines which telegram function and which subtelegram is requested by the master. The datatype of this parameter is 8 bit binary. The upper 4 bits define the telegram type or telegram application and the lower 4 bits define the number of the subtelegram (the meaning of this number is device specific). The lower four bits may be ignored for slaves which provide only a single telegram for each application. The use of the value zero for the number of the subtelegram means that all telegrams are requested. Slaves with only one type of telegram may ignore application reset and the added parameters. The following codes can be used for the upper 4 bits of the first parameter: Table 2 Coding of the upper four bits of the first parameter after CI = 50h Coding Description Examples 0000b All 0001b User data consumption 0010b Simple billing actual and fixed date values + dates 0011b Enhanced billing historic values 0100b Multi tariff billing 0101b Instaneous values for regulation 0110b Load management values for management 0111b Reserved 1000b Installation and startup bus address, fixed dates 1001b Testing high resolution values 1010b Calibration 1011b Manufacturing 1100b Development 1101b Selftest 1110b Reserved 1111b Reserved Note that this table has been expanded with optional elements from the original standard.
