What is BS EN 62056-7-6 - 3-layer, connection-oriented HDLC communication profile about ?
DLMS/COSEM is the global standard for energy & water smart management, advanced control and innovative utility meter data exchange. It specifies an object-oriented data model, an application layer protocol and media-specific communication profiles.
BS EN 62056 is a series of European Standards that discusses electricity metering data exchange through the DLMS/COSEM suite.
BS EN 62056-7-6 is a part of BS EN 62056 series that specifies the DLMS/COSEM 3-layer, connection-oriented HDLC based communication profile.
Who is BS EN 62056-7-6 - 3-layer, connection-oriented HDLC based communication profile for ?
BS EN 62056-7-6 on the DLMS/COSEM suite is relevant to: 
- Power distribution and transmission companies
- Utility companies
- Communication media network providers
- Local authorities
- Regulatory bodies
- Quality control and testing personnel
- Engineers
Why should you use BS EN 62056-7-6 - 3-layer, connection-oriented HDLC based communication profile ?
BS EN 62056-7-6 defines the 3-layer, CO, HDLC-based profile as suitable for local data exchange with metering equipment via direct connection, or remote data exchange via the PSTN or GSM networks with appropriate modems.
BS EN 62056-7-6 also mentions three-layer (collapsed) OSI protocol architecture:
- the DLMS/COSEM AL, specified in IEC 62056-5-3
- the data link layer based on the HDLC standard, specified in IEC 62056-46
- the physical layer; specified in IEC 62056-42
BS EN 62056-7-6 provides guidance on targeted communication environments, structure of the profile, identification and addressing scheme, supporting layer services and service mapping, and considerations and constraints to be taken into account.
By complying with BS EN 62056-7-6 guidelines, you can expand the scope of DLMS / COSEM to cover new applications and new communication media that support interoperability and efficient data collection and exchange.
