LonTalk definition

LonTalk is a communication protocol for networking devices over media such as twisted pair, powerlines, fiber optics, and RF. It supports long-range and reliable communication between various devices.

LonTalk is highly robust, functions in a wide range of conditions, and uses a peer-to-peer network structure — any device on the network can communicate with any other device without having to pass through a central controller. This decentralized approach enhances the network’s reliability because it can continue to operate even if individual nodes fail. LonTalk is part of the LonWorks networking platform.

History of LonTalk

Echelon Corporation, a company based in San Jose, California, developed LonTalk. In 1990, as a part of Echelon’s efforts to create an open, interoperable standard for networking a wide variety of devices, it introduced the LonWorks system with the LonTalk protocol.

Over the next few years, LonWorks technology and the LonTalk protocol gained traction in several industries, particularly in building automation and control. In 1999, the LonTalk protocol was submitted to ANSI (American National Standards Institute) and became a standard (ANSI/EIA/CEA 709.1-B-2002). Later, it was also accepted as a standard by international bodies, including IEEE and IEC.

While the LonTalk protocol is not as widely known as networking technologies like Ethernet or Wi-Fi, it’s been an important solution in building automation, transportation, and utilities because of its robustness and versatility.
