IEC 61850-7-2:2010+A1:2020 applies to the ACSI communication for utility automation. The ACSI provides the following abstract communication service interfaces: abstract interface describing communications between a client and a remote server; and 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).
Major technical changes with regard to the previous edition are as follows: data types not required have been removed, service tracking for control blocks have been added, security issues are solved by the IEC 62351 series, service tracking for control blocks have been added, the view concept will be according to the new work on role bases access (RBA), security issues are solved by the IEC 62351 series. This publication is of core relevance for Smart Grid. This consolidated version consists of the second edition (2010) and its amendment 1 (2020).
