Communication gateway TX MODBUS 600-041

telemetryIoTRS-485

Overview
The LoRa Easy Modbus master transmitter by Enless enables retrieval and transmission of data between Modbus slaves and an Enless LoRa Easy Modbus receiver over a radio link. It reads and writes up to 60 Modbus registers across up to 10 slaves, creating a radio bridge between your Modbus devices and the BMS.

Protocol
Compatible with Enless's proprietary LoRa Easy protocol. This transmitter is not compatible with LoRaWAN networks and communicates exclusively with an Enless LoRa Easy Modbus receiver.

Operation
The transmitter connects on the Modbus slave side (RS485) to read or write registers. Data are transmitted by radio to an Enless LoRa Easy Modbus receiver, which forwards the information to the BMS. It is possible to send commands from the receiver to perform write operations on the slaves.

Use cases

• Energy meters with Modbus interface
• Air handling units (AHUs) for supervision and control
• Chiller units for optimized cooling production control
• Heat pumps
• Integration with any RS485‑compatible Modbus slave
