Message
Inherent attribute of a communication between IEDs, functions or instances, that
conveys service-specific data or commands, on receipt of which it is expected
that action is taken.
Model
A simplified representation of some aspects of reality. The purpose of creating a
model is to facilitate understanding, description, or prediction of something that is
difficult or impossible to directly observe in the real world, by providing the
opportunity for exploration of a simplified representation of a particular entity or
phenomenon.
Model Implementation Conformance Statement
Details the standard data object models supported by the system or device.
Multicast
Uni-directional, connectionless communication between a server and a selected
set of Clients.
N
Name Plate
Name for the set of data typically found on an item of a plant (for example, a
power transformer) or on an IED (for example, a protection relay) that uniquely
describes that device's identity and attributes.
Negative Test
Test to verify the correct response of a device or system to the following
standards:
 IEC 61850-conformant information and services which are not implemented
in the device or system under test
 Non-IEC 61850-conformant information and services sent to the device or
system under test
Network Layer
Layer 3 of the OSI reference model for Open Systems Interconnection. It
provides functional and procedural means of connectionless or connection-mode
transmission, also independence from routing and communications-relaying
considerations, enabling the transparent transfer of data between transport
entities.
O
Object Attribute
Field or a category or value of data that, together with other attributes, specify the
services or data values related to the function and performance of an object.
