3 THE standard for smart metering DLMS Device Language Message Specification COSEM: Companion Specification for Energy Metering OBIS: Object Identification System All energy types, all applications, all communication media First published in 1998: high end >> low end applications IEC standard since 2002 : Ed. 4 in 2015, Ed. 5 in 2016 Large smart meter rollouts worldwide Supported by the DLMS User Association: 300+ members 562 meter types certified to 80+ manufacturers Okos Jövő DLMS Slide No: 3

4 Modelling Messaging Transport Separation of model and protocol: orthogonality 1. Modeling COSEM Interface Objects Register 0..n Class_id=3, Version=0 Attribute(s) Data Type Min Max Def 1. logical_name (static) octet-string 2. value ( dyn.) instance specific 3. scaler -unit (static) scal _unit_type Method(s) m/o 1. reset o Data model, to view the meter functionality at its interface(s) COSEM objects OBIS Object Identification System Messaging method to communicate with the model and to represent data as a series of bytes (APDUs) Transportation method to carry the s over the media between the meter and remote parties Protocol Services to access attributes and methods 2. Messaging C FF Transporting Communication Protocol Messages: Service_Id( Class_Id, Instance_Id, Attribute_Id/Method_Id ) Encoding: (GET-request APDU) Okos Jövő DLMS Slide No: 4

5 DLMS/COSEM framework: IEC COSEM object-oriented data model IEC COSEM interface classes IEC / EN OBIS Object Identification System Services for connection establishment and for accessing COSEM objects IEC DLMS/COSEM Application layer Lower layer standards IEC IEC EN ITU-T RFC Comm. Profiles for Local Networks IEC / 6-7 series Comm. Profiles for Neighbourhood Networks IEC series Comm. Profiles for Wide Area Networks IEC series Okos Jövő DLMS Slide No: 5

6 Communication interfaces Smart metering functions Supply network Supply interface Security function Time function Connected supply Recording function Metering function Tariff control function Metered supply Meter application process Accounting function Delivery & load control function Display& keyboard H2M interface Delivered supply Data exchange function M2M interface Test function Load circuit Load interface Okos Jövő DLMS Slide No: 6 The COSEM object model describes all metering functions in a communication medium independent way

7 E2E security Access security, messsage security, data security Several protection layers can be applied by market participant, client, server Authentication (Integrity), encryption (Confidentiality), digital signature (Non-repudiation) Protection can be applied selectively where needed

8 Efficiency Selective access: get only what you need Eliminate overhead: Compact data Many data with one request: with-list Message length fits media: segmentation Compression Push and pull operation Objectives: meet media specific restrictions, minimize overhead and number of round trips >> minimize costs Okos Jövő DLMS Slide No: 8

9 Communication media and profiles Specify how to use DLMS/COSEM over the media-specific lower layers Lower layers Media 1: PSTN, GSM COSEM Application layer Connection COSEM object model Lower layers Media 2: TCP/IP Messaging Lower layers Media n Profile 1 Profile 2 Profile n Object model: common in all communication profiles. Supports the use cases Application layer: common in any communication profile connection between the metering and data collection application processes prepares the s for transport encoding cryptographic protection block transfer Lower layers ensure that he s are correctly delivered e.g. HDLC, TCP/IP, S-FSK PLC, PRIME PLC. G3-PLC, BPLC, M-Bus... Okos Jövő DLMS Slide No: 9
