Communication networks and systems for power utility automation - Part 7-2: Basic information and communication structure - Abstract communication service interface (ACSI)
This part of IEC 61850 applies to the ACSI communication for utility automation. The ACSI
provides the following abstract communication service interfaces.
a) Abstract interface describing communications between a client and a remote server for
– real-time data access and retrieval,
– device control,
– event reporting and logging,
– setting group control,
– self-description of devices (device data dictionary),
– data typing and discovery of data types, and
– file transfer.
b) Abstract interface for fast and reliable system-wide event distribution between an application
in one device and many remote applications in different devices (publisher/sub-scriber)
and for transmission of sampled measured values (publisher/subscriber).
