APPENDIX C IEC 61850 COMMUNICATIONSC.1INTRODUCTION
The IEC 61850 standard is the result of years of work by electric utilities and vendors of electronic equipment to produce
standardized communications systems. IEC 61850 is a series of standards describing client/server and peer-to-peer com-
munications, substation design and configuration, testing, environmental and project standards. The complete set includes:
• IEC 61850-1: Introduction and overview
• IEC 61850-2: Glossary
• IEC 61850-3: General requirements
• IEC 61850-4: System and project management
• IEC 61850-5: Communications and requirements for functions and device models
• IEC 61850-6: Configuration description language for communication in electrical substations related to IEDs
• IEC 61850-7-1: Basic communication structure for substation and feeder equipment - Principles and models
• IEC 61850-7-2: Basic communication structure for substation and feeder equipment - Abstract communication service
interface (ACSI)
• IEC 61850-7-3: Basic communication structure for substation and feeder equipment – Common data classes
• IEC 61850-7-4: Basic communication structure for substation and feeder equipment – Compatible logical node classes
and data classes
• IEC 61850-8-1: Specific Communication Service Mapping (SCSM) – Mappings to MMS (ISO 9506-1 and ISO 9506-2)
and to ISO/IEC 8802-3
• IEC 61850-9-1: Specific Communication Service Mapping (SCSM) – Sampled values over serial unidirectional multi-
drop point to point link
• IEC 61850-9-2: Specific Communication Service Mapping (SCSM) – Sampled values over ISO/IEC 8802-3
• IEC 61850-10: Conformance testing
These documents can be obtained from the IEC (http://www.iec.ch). It is strongly recommended that all those involved with
any IEC 61850 implementation obtain this document set.
The D60 relay supports IEC 61850 server services over both TCP/IP and TP4/CLNP (OSI) communication protocol stacks.
The TP4/CLNP profile requires the D60 to have a network address or Network Service Access Point (NSAP) to establish a
communication link. The TCP/IP profile requires the D60 to have an IP address to establish communications. These
addresses are located in the
supports IEC 61850 over the TP4/CLNP or TCP/IP stacks, and also operation over both stacks simultaneously. It is possi-
ble to have up to four simultaneous connections (in addition to DNP and Modbus/TCP (non-IEC 61850) connections).
IEC 61850 specifies the use of the Manufacturing Message Specification (MMS) at the upper (application) layer for transfer
of real-time data. This protocol has been in existence for a number of years and provides a set of services suitable for the
transfer of data within a substation LAN environment. Actual MMS protocol services are mapped to IEC 61850 abstract ser-
vices in IEC 61850-8-1.
Peer-to-peer communication of digital state information (remote inputs/outputs) is supported using the IEC 61850 GSSE
and GOOSE services. This feature allows digital points to be exchanged between IEC 61850 conforming devices.
MMS file services are supported to allow transfer of oscillography, event record, or other files from a D60 relay.
