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.
