Description
Software and description XML files to provide device
specific information about certain relays or device,
used to ease and simplify the engineering
Data communication protocol developed by ABB
Connector type for glass fibre cable
Connector type for plastic fibre cable
Connector type for glass fibre cable
Part of a logical node object representing specific
information, for example status or measurement. From
an object-oriented point of view a data object is an
instance of a class data object. DOs are normally used
as transaction objects; i.e., they are data structures.
The data set is the content basis for reporting and
logging. The data set contains references to the data
and data attribute values.
This includes devices containing advanced logics
such as meters, relays, and trip units. In this article
IED means a physical IEC 61850 device that behaves
as its own communication node in the IEC 61850
protocol.
Representation of a group of functions. Each function
is defined as a logical node. A physical device has one
or several LDs.
The smallest part of a function that exchanges data. A
LN is an object defined by its data and methods.
The report control block controls the reporting process
for event data as they occur. The reporting process
continues as long as the communication is available.
Short Address Information
The sAddr attribute allows the allocation of a short
address to DO attributes. Short addresses can be
used within the communication to be more efficient
either in the communication, or in the handling of
messages at client or server. Furthermore, they can
be used as IED internal identification for the attribute.
XML-based description language for configurations of
electrical substation IEDs. Defined in the IEC 61850
standard.
