This paper presents a three‑phase power‑line data acquisition system using Echelon LonWorks technology with PLT‑22 transceivers and RTR‑10 routers.
The article describes a three‑phase data‑collection system that uses power lines as the communication medium. It leverages LonWorks fieldbus technology, developed by Echelon, to enable reliable data transfer over low‑voltage power networks.
The system architecture consists of data nodes, a concentrator, a router, a modem and a remote PC. Key components include the PLT‑22 power‑line transceiver, the Neuron3150 communication chip, and the RTR‑10 router core module, which together provide dual‑band carrier transmission, noise mitigation, and inter‑subnet routing.

| Carrier frequencies of PLT‑22 | 132 kHz and 115 kHz |
|---|---|
| Minimum SNR for PLT‑22 reception | ≥ 2 : 1 |
It operates on dual carrier frequencies of 132 kHz and 115 kHz.
A signal‑to‑noise ratio of at least 2 : 1 is needed.
