BS EN 62056-4-7:2016

This standard BS EN 62056-4-7:2016 Electricity metering data exchange. The DLMS/COSEM suite is classified in these ICS categories:

• 17.220.20 Measurement of electrical and magnetic quantities
• 35.100.40 Transport layer
• 17.220.01 Electricity. Magnetism. General aspects
• 91.140.50 Electricity supply systems
• 35.110 Networking

IEC 62056-4-7:2015 specifies a connection-less and a connection oriented transport layer (TL) for DLMS/COSEM communication profiles used on IP networks. These TLs provide OSI-style services to the service user DLMS/COSEM AL. The connection-less 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). This first edition cancels and replaces the IEC 62056-47 published in 2006 and constitutes a technical revision. It includes the following changes:
- This standard is applicable now both for IP4 and IPv6 networks;
- Latest editions of the IEC 62056 suite are referenced. DLMS/COSEM IANA-registered port numbers added.
