Why IEC 61850 Matters in Modern Substations The core strength of IEC 61850 for Substation Automation lies in its object-oriented data models. 3 IEC 61850 Application View 3. The ClcMth is a data object defined in common logical node class (inherited by MMXU logical node). The device supports IEC 61850, Edition 2. As an international standard in the field of substation automation, IEC 61850 solves equipment interoperability issues through three major innovations: Object-Oriented Modeling: Equipment IEC 61850 is the international standard for communication networks and systems in power utility automation, especially substation automation. IEC 61850 features include: Data modelling – Primary process objects as well as protection and control functionality in the substation is modelled into different standard logical nodes which IEC 61850 standard was developed primarily for communication with digital protection relays. This manual describes the Model Implementation Conformance Statement (MICS) explaining the imple-mented logical nodes and data objects of the IEC 61850 interface. Based on this definition, the intelligent logical nodes architecture (iLN) is used to organize the .
