Description

BS PD IEC/TS 62056-8-20:2016 specifies a DLMS/COSEM communication profile that can be used in asmart metering system in which the Neighbourhood Networks (NN) are mesh networks.

This profile may be considered as an adaptation and extension of the UDP/IP communicationprofile specified in IEC 62056-9-7:2013. As in that standard, the PHY and MAC layers are outof the Scope.

This Technical Specification specifies a number of features essential to the efficient operationof a large scale AMI using mesh NNs. These features include:

  • identification of the DLMS/COSEM client and server participating in an applicationassociation (AA) with their system title, so that this identification does not change whenthe IP address of the server changes, see Clause 6;
  • a mechanism to inform the client of the binding between the server’s system title and itscurrent IP address(es), see 5.5.3;
  • the use of the DLMS/COSEM UDP based transport layer, that allows keepingDLMS/COSEM AAs open for long periods, while the device may leave and join the meshNN and/or its IP address may change, see 7.2.2;
  • DLMS/COSEM application layer and application process level security features that canbe used in a mesh environment, see 7.4.2;
  • a mechanism to organize servers to one or more groups based on various conditions, sothat the requests can be broadcasted to all devices attached to the mesh network, but onlythose servers belonging to the group carry out the request and respond, see 8.2;
  • a mechanism that allows to send the response to a request in designated time windowsand with a randomized delay, see 8.3.
  • the use of a specific UDP port that allows efficient UDP header compression, see 6.3.3.

The Scope of this communication profile specification is restricted to aspects concerning theuse of communication protocols in conjunction with the COSEM data model and theDLMS/COSEM application layer. Any project specific definitions of data structures and datacontents may be provided in project specific companion specifications.
