INTRODUCTION 61850-7-2
This document is part of a set of specifications which details a layered substation communication
architecture. This architecture has been chosen to provide abstract definitions of
classes and services such that the specifications are independent of specific protocol stacks,
implementations, and operating systems.
The IEC 61850 series is intended to provide interoperability between a variety of substation
and feeder devices. Communication between these devices is achieved by the definition of a
hierarchical class model (for example, logical device, logical node, data, data set, report
control, or log) and services provided by these classes (for example, get, set, report, define,
delete) in parts IEC 61850-7-x.
This part of IEC 61850 defines the abstract communication service interface (ACSI) for use in
the utility substation domain that require real-time cooperation of intelligent electronic devices.
The ACSI has been defined so as to be independent of the underlying communication systems.
Specific communication service mappings3 (SCSM) are specified in part 8-x and part 9-x of this
standard.
