Communication systems for meters - Part 4: Wireless M-Bus communication

This European Standard specifies the requirements of parameters for the physical and the link layer for systems using radio to read remote meters. The primary focus is to use the Short Range Device (SRD) unlicensed telemetry bands. The standard encompasses systems for walk-by, drive-by and fixed installations. As a broad definition, this European Standard can be applied to various application layers.

Kommunikationssysteme für Zähler und deren Fernablesung - Teil 4: Zählerauslesung über Funk (Fernablesung von Zählern im SRD-Band)

Systèmes de communication pour compteurs - Partie 4 : Communication sans fil M-Bus

La présente Norme européenne spécifie les exigences applicables aux paramètres de la couche physique et de la couche liaison associées aux systèmes de télérelevé de compteurs par radio. Elle est centrée essentiellement sur l’utilisation des bandes de télémesure libres pour dispositifs à courte portée (SRD). Elle traite à la fois des systèmes de relevé mobile à pied ou par véhicule et des installations fixes. La présente Norme européenne peut s’appliquer, par extension, à diverses couches application.

Komunikacijski sistemi za števce - 4. del: Brezžično komuniciranje po M-vodilu

Ta evropski standard določa zahteve parametrov za fizično plast in plast podatkovne povezave za sisteme, ki za daljinsko odbiranje števcev uporabljajo radijske valove. Osnovni cilj je uporaba nelicenciranih telemetričnih pasov za naprave kratkega dosega (SRD). Standard zajema sisteme za prehodne, prevozne in stacionarne naprave. Ta evropski standard se lahko kot široka definicija uporablja za različne aplikacijske nivoje.

European foreword

This document (EN 13757-4:2019) has been prepared by Technical Committee CEN/TC 294

“Communication systems for meters”, the secretariat of which is held by DIN.

This European Standard shall be given the status of a national standard, either by publication of an

identical text or by endorsement, at the latest by November 2019, and conflicting national standards

shall be withdrawn at the latest by November 2019.

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. CEN shall not be held responsible for identifying any or all such patent rights.

This document supersedes EN 13757-4:2013.

This document has been prepared under a mandate given to CEN by the European Commission and the

European Free Trade Association.
The main changes since EN 13757-4:2013 are as follows:
— Referenced standards have been updated to the most recent versions;

— Mode N, in the 169 MHz band has been extended to cover more frequencies see Clause 10;

— New C-field function code (Send User Data – No reply) added see 12.5.4;
— Extended timing tolerances for synchronous transmission see 12.6.2;
— Optional Forward Error Correction in the Link Layer added see 12.8;
— CI field for selectable Extended Link Layer added see 13.2;
— Management functions for link control added see Clause 14.

The standard is not affected by any of the requirements in Directive 2004/22/EC as it only covers the

basic transmission of information from the meter to an external entity. The standard ensures that data

transmitted cannot be modified without it being detected. Confidentiality, integrity and authenticity are

provided by the capabilities specified in other parts of the EN 13757 series of standards. The standard

does not specify any of the metering capabilities of the meter nor the metrological capabilities of the

meter.

The standard enables encrypted transfer data either directly or as specified in other parts of the

EN 13757 series of standards. The encryption ensures the confidentiality of any personal data.

The standard provides capabilities of interoperability of meters as requested in M/441 which can be

used to improve the customer awareness of actual consumption.

According to the CEN-CENELEC Internal Regulations, the national standards organisations of the

following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,

Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,

France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,

Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland,

Turkey and the United Kingdom.
