Babi-LON

The Babi-LON™ platform offers the most scalable development environment for your IoT applications. It is available under Linux and RTOS. It is the most open solution as it is ISO 14908 (LON) and ISO 16484 (BACnet) compliant.
It does not use a single specific component for long-term sustainability. Compared to the discontinued Neuron® Chip, the Babi- LON platform gives you the resources, scalability and sustainability you need to guarantee the long-term life of your products.
Small footprints with low costs under RTOS or powerful applications under Linux – the choice is yours. AI is supported for all hardware architectures. Media support including the user-friendly and robust Free Topology structure and Powerline provides complete IP networks with simple cabling.

FetLON

FetLON Stack

FetLON Stack is a reliable and versatile solution for the LON® protocol. Using a patented solution for decoding the Differential Manchester encoded LON® messages, it enables the processing of the LON® protocol on commercially available microcontrollers.

With its minimum operating system requirements and its scalable design it is adaptable to different operating systems (including Zephyr, FreeRTOS or Bare Metal environments) as well as to different storage types and storage sizes.

Its small footprint and low performance demands on processors allow for single-chip solutions for typical LON® devices. Two-chip solutions are also possible for applications with higher computing power requirements.

Overview FetLON Stack
BV2021-8 – LonWorks® FT/LP Compatible Communications Transformer

The BV2021-8 is a Communications Transformer compatible with LonWorks® Free Topology and Link Power networks using the ISO/IEC 14908.1 (ANSI/CTA 709.1 D or EN 14908.1) Control Network Protocol.

Originally, the BV2021-8 was designed to be used with the Echelon® FT 5000® Smart Transceiver. It can be used as a replacement for the FT-X3® Communications Transformer. It is also part of the bus-coupling circuit for LON® devices that incorporate the FetLON Stack.

The BV2021-8 has been designed and tested according to the Echelon® compatibility specification.

Protocol Stack

The LON Stack DX enables Industrial IoT developers to build networks of communicating devices using any processor supporting the C programming language. Devices with the LON Stack DX can exchange data with each other on an easy-to-use publish-subscribe data model over IP or native LON channels. LON devices can collect data from physical sensors built to monitor the built environment including temperature, humidity, light-level, power-consumption, or moisture, and make the data available to other LON devices in the same network. Using data received from other LON devices or local sensors, LON devices can also control physical actuators such as LED dimmers, motor controllers, damper controllers, and solenoids. The LON protocol is an open standard defined by the ISO/IEC 14908 series of standards.

Nessum

Overview

Nessum technology, standardized under ANSI/CTA 709.8 and EN 14908-8, delivers a high-speed LON channel with international recognition. It is based on the IEEE 1901 standard, specifically the latest IEEE 1901c specification. Nessum ensures outstanding network performance and state-of-the-art security.
It supports multiple physical layers, including power line and twisted pair. On twisted pair, Nessum can operate in parallel—without interference—with LON TP/FT10 or BACnet MS/TP over RS485.
The required LON stack, such as EnOcean’s DX, can run either directly on the Nessum microcontroller or on a separate chip using the Nessum controller as a PHY. Multiple vendors supply Nessum-compatible silicon.
Nessum-based LON designs have been successfully deployed in smart streetlighting and building automation projects. Visit and register at nessum.org to explore all the features.
