COSEM Application layer

Connection Messaging

COSEM object model

Lower layers

Media 1: PSTN, GSM

Lower layers

Media 2: TCP/IP

Lower layers

Media n

Application layer: common in any communication profile

• connection between the metering and data collection application processes

• prepares the messages for transport

• encoding

• cryptographic protection

•block transfer

Lower layers ensure that he messages are correctly delivered

Profile 1 Profile 2 Profile n


Object model: common in all communication profiles. Supports the use cases

Specify how to use DLMS/COSEM over the media-specific lower layers

device


Communication profiles • Communication media independent data model: COSEM • Application layer common for all profiles: DLMS/COSEM • Media dependent connection mgr.: e.g. TCP conn. manager, S-FSK CIASE • Adaptation / convergence layer (when needed) • Media specific lower layers • Communication profiles driven by technology evolution:

– 3-layer HDLC based profile – TCP-UDP-IP profile – S-FSK PLC profile – Narrow-band OFDM PLC profile for PRIME networks (PRIME Alliance) – Narrow-band OFDM PLC profile for G3-PLC networks (G3-PLC Alliance) – SMITP / B-PSK PLC profile (Meters & More association) – AMC-SS PLC profile (Siemens) – ISO/IEC 12139-1 BPL profile (Korea) – RF mesh profile (US National Committee) – Wired and wireless M-Bus profile (CEN TC 294)

Summary

The DLMS/COSEM model and application layer is successfully used over a range of communication media specific lower layers

Using the same COSEM model ensures semantic interoperability

Using the same DLMS/COSEM application layer ensures syntactic interoperability

All DLMS/COSEM application level security features are available the same way

Standardizing the communication profiles ensures network interoperability
