PD CEN/TR 17167:2018CEN/TR 17167:2018 (E) 6 Introduction This document belongs to a series of parts of EN 13757, which covers communication systems for meters and remote r

26、eading of 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 13757-3 contains detailed description of the application protocols especially the M-Bus Protocol. EN 13757-4 describes

27、 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 137577 describes transport mechanis

28、m and security methods for data. These upper M-Bus protocol layers can be used with various physical layers and with 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) an

29、d 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 batte

30、ry 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 po

31、wer. An overview of communication systems for meters is given in EN 13757-1, which also contains further definitions. This document 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

32、 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 meters and heat cost allocato

33、rs) and for electricity meters, in this document 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

34、in the responsibility of CENELEC. Table 1 gives an overview of the annexes as well as a reference to the corresponding Annexes in the former EN 13757-3:2013 where applicable.
