BS EN IEC 62056 discusses electricity metering data exchange. BS EN IEC 62056‑6‑2 is the sixth part of BS EN IEC 62056 multi-series discusses COSEM interface classes.
BS EN IEC 62056‑6‑2 specifies a model of a meter as it is seen through its communication interface(s). Generic building blocks are defined using object-oriented methods, in the form of interface classes to model meters from simple up to very complex functionality.
BS EN IEC 62056‑6‑2 on electricity metering data exchange is useful for:
Driven by the business needs of the energy market participants – generally in a liberalized, competitive environment – and by the desire to manage natural resources efficiently and to involve the consumers, the utility meter became part of integrated metering, control and billing system. The meter is not anymore, a simple data recording device but it relies critically on communication capabilities. Ease of system integration, interoperability, and data security are important requirements.
COSEM, the Companion Specification for Energy Metering, addresses these challenges by looking at the utility meter as part of a complex measurement and control system. The meter must be able to convey measurement results from the metering points to the business processes which use them. It also must be able to provide information to the consumer and manage consumption and eventually local generation.
BS EN IEC 62056‑6‑2 COSEM interface classes form an extensible library. Manufacturers use elements of this library to design their products that meet a wide variety of requirements. The concept of the BS EN IEC 62056‑6‑2 interface class library provides different users and manufacturers with a maximum of diversity while ensuring interoperability.
