18.6 LON communication protocol
18.6.1 Functionality
An optical network can be used within the substation automation system. This enables
communication with the IED through the LON bus from the operator’s workplace, from
the control center and also from other terminals.
LON communication protocol is specified in LonTalkProtocol Specification Version 3
from Echelon Corporation and is designed for communication in control networks. These
networks are characterized by high speed for data transfer, short messages (few bytes),
peer-to-peer communication, multiple communication media, low maintenance,
multivendor equipment, and low support costs. LonTalk supports the needs of
applications that cover a range of requirements. The protocol follows the reference model
for open system interconnection (OSI) designed by the International Standardization
Organization (ISO).
In this document the most common addresses for commands and events are available. For

It is assumed that the reader is familiar with LON communication protocol in general.
