Operational information and controls are available through a wide range of communication protocols including IEC 61850 and Modbus®. Full communication capabilities, for example, horizontal communication between the relays, are only enabled by IEC 61850.
The IEC 61850 protocol is a core part of the relay as the protection and control application is fully based on standard modelling. IEC 61850 standard is updated with a new version, Edition 2.1, which extends to new application areas intransmission and distribution power systems and also defines new functionality.The relay supports Edition 2 version of the standard. With Edition 2 support, the relay has the latest functionality modelling for substation applications and the best interoperability for modern substations.
