BS EN 62056 discusses electricity metering data exchange. BS EN 62056-4-7 belongs to BS EN 62056 multi-series and discusses DLMS/COSEM transport layer for IP networks.
BS EN 62056-4-7 specifies a connection-less and a connection-oriented transport layer (TL) for DLMS/COSEM communication profiles used on IP networks.
BS EN 62056-4-7 on electricity metering data exchange is useful for:
These TLs (transport layers) provide OSI-style services to the service user DLMS/COSEM AL. The connectionless TL is based on the Internet Standard User Datagram Protocol (UDP). The connection-oriented TL is based on the Internet Standard Transmission Control Protocol (TCP). The DLMS/COSEM TL consists of the UDP or TCP transport layer TCP and an additional sublayer, called wrapper.
BS EN 62056-4-7 guides you with the DLMS/COSEM connection-less, UDP-based transport layer that includes service specification for the DLMS/COSEM UDP-based transport layer and protocol specification for the DLMS/COSEM UDP-based transport layer. BS EN 62056-4-7 guides you with the DLMS/COSEM connection-oriented, TCP-based transport layer that includes service specification and protocol specification of the DLMS/COSEM TCP-based transport layer. BS EN 62056-4-7 helps you with a connection-less and connection-oriented DLMS/COSEM transport layer for IP networks.
