17、5 (E) 4 Introduction This European Standard is part of a series of standards which covers communication systems for meters and remote reading of meters. EN 13757-1 contains generic descriptions and a communication protocol, EN 13757-2 contains the description of the physical and link layer of a univ
18、ersal twisted pair bus system (M-Bus), EN 13757-3 contains higher protocol layers like transport or application layer, EN 13757-4 specifies wireless communication and EN 13757-5 specifies a relaying extension of EN 13757-4. This European Standard can be used with various link and application layers.
19、 Frequently, the application layer of EN 13757-3 (M-Bus) or the DLMS based application layer described in EN 13757-1 is used. An overview of communication systems for meters is given in EN 13757-1, which also contains further definitions. BS EN 13757-6:2015EN 13757-6:2015 (E) 5 1 Scope This European
20、 Standard specifies the physical layer parameters of a local meter readout system (“Local Bus”) for the communication with and the readout of a single meter or a small cluster of meters via a single battery powered readout device (“master”) which can be connected temporarily or stationary for the co
21、mmunication directly to a meter (i.e. local readout) or via a fixed wiring or a small bus (i.e. remote readout). For generic descriptions concerning communication systems for meters and remote reading of meters, refer to EN 13757-1. 2 Normative references The following documents, in whole or in part
22、, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 13757-2, Communication systems for meters and re
23、mote reading of meters Part 2: Physical and link layer 3 Physical Layer Specifications The Local Bus is an alternative to the M-Bus. It is restricted to small installations (Mini installation according to EN 13757-2:2004, Annex E.6.1 type E) and optimized for special battery-driven masters. Usually
24、the readout frequency is limited by the meter. The total cable length is limited to 50 m. The Local Bus does not support meter power supply from the bus. Note that this meter interface is not compatible with M-Bus masters according to EN 13757-2. To facilitate the meter power management, the master
25、shall switch the bus power on (i.e. enter the master mark send state) not more than 10 s before any meter communication. NOTE Annex A shows a possible circuit diagram for implementing such an interface. A meter equipped with a Local Bus interface shall meet the requirements of Table 1. BS EN 13757-6
