IEC 61850-7-2 Edition 2 approved

IEC 61850-7-2 Edition 2: "Communication networks and systems for power utility automation - Part 7-2: Basic information and communication structure - Abstract communication service interface (ACSI)" has been approved  for publication as International Standard Edition 2 on July 02, 2010.

This edition 2 adds some minor new definitions, corrects errors of the first edition and aligns the content with other parts, e.g., 8-1. Here is a list of the most crucial issues:

  • class diagrams have been updated (the modeling method is quite close to an UML model)
  • data types not required have been removed, new types have been added,
  • errors and typos haven been corrected (see tissue database),
  • substitution model has been moved to IEC 61850-7-3,
  • service tracking for control blocks have been added; in edition 1 it was possible to treat control block instances in the same way as Data Objects. This has been changed - from a modeling point of view only. T
  • the view concept (access restriction) will be implemented with the new work on role bases access (RBA) as part of IEC 62351-8,
  • security issues are solved by the IEC 62351 series, and
  • several terms have been harmonized with those defined in other parts

Part 7-2 contains the basic definitions of the models and the services:
