BS EN IEC 62056 discusses electricity metering data exchange. BS EN IEC 62056‑3‑1 is the third part of the IEC 62056 multi-series and discusses use of local area networks on twisted pair with carrier signalling.
BS EN IEC 62056‑3‑1 describes two sets of profiles: the first set of profiles allows bidirectional communication between a client and a server. This set of profiles is made of three profiles allowing local bus data exchange with stations either energized or not. For non-energized stations, the bus supplies energy for data exchange. Three different profiles are supported:
Note 1- This first profile was published in IEC 61142:1993 and became known as the Euridis standard
Note 2-This second profile was published in IEC 62056-31:1999.
The three profiles use the same physical layer, and they are fully compatible, meaning that devices implementing any of these profiles can be operated on the same bus. The transmission medium is twisted pair using carrier signaling and it is known as the Euridis Bus.
The second set of profiles allows unidirectional communication between a given energy metering device and a Customer Energy Management System. This second set is made up of three profiles.
BS EN IEC 62056‑3‑1 on electricity metering data exchange the DLMS/COSEM suite useful for :
Electricity metering data exchange make meter reading easier, and the system can also provide more advanced services, such as storage of load curves and monitoring of customer consumption. BS EN IEC 62056‑3‑1 provides you with the Euridis Bus where Each meter is linked to the Euridis local bus, which consists of a two-wire cable connected to a magnetic coupler, generally located in the public domain. The operator simply connects a handheld unit to the magnetic coupler so that it can read each meter safely. This is the best and most economical solution in the case of new housing.
BS EN IEC 62056‑3‑1 guides you with the unidirectional communication interface from a Metering device to Consumer Energy Management Systems. This interface is called TIC, Transmission of Information to the Customer. The TIC "Transmission of Information to the Customer" constantly sends out the managed contractual parameters, as well as consumption levels measured by the metering device.
