'' — Primary process objects as well as protection and control functionality in the substation is modelled into different standard logical nodes which can be grouped under different logical devices. There are logical nodes for data/functions related to the logical device (''LLN0'') and physical device (''LPHD''). # ''Reporting Schemes'' — There are various reporting schemes (''BRCB & URCB'') for reporting data from server through a server-client relationship which can be triggered based on pre-defined trigger conditions. # ''Fast Transfer of events'' — Generic Substation Events (''GSE'') are defined for fast transfer of event data for a peer-to-peer communication mode. This is again subdivided into ''

'' & ''GSSE''. # ''Setting Groups'' — The setting group control Blocks (''SGCB'') are defined to handle the setting groups so that user can switch to any active group according to the requirement. # ''Sampled Data Transfer'' — Schemes are also defined to handle transfer of sampled values using Sampled Value Control blocks (''SVCB'') # ''Commands'' — Various command types are also supported by IEC 61850 which include direct & select before operate (SBO) commands with normal and enhanced securities. # ''Data Storage'' —
