Modbus device server RX MODBUS 500-302

EthernetserialRS-232

Overview
Simplify the integration of data from Enless sensors with the LoRa Easy Modbus Receiver. Designed to communicate exclusively with Enless sensors using the LoRa Easy protocol, the receiver centralizes sensor data and automatically converts it into a Modbus register map for direct use by PLCs and Building Management Systems (BMS). It provides a cost-effective bridge to process Enless LoRa sensor data on automation controllers.

Key benefits

• Native decoding of Enless LoRa frames via the LoRa Easy protocol.
• Automatic conversion of received frames into a Modbus register table for quick PLC/BMS integration.
• Supports Modbus TCP/IP and Modbus RTU (RS485 or RS232).
• Manages up to 50 Enless sensors.
• Built-in configuration server (embedded web interface) for fast pairing, configuration and real-time link quality monitoring.

How it works (quick deployment)

• 1. Access the server — Use the receiver’s embedded configuration server to set up the device and register sensors. The interface is simplified for fast setup and verification of received frames.
• 2. Pair your sensors — Enter sensor IDs on the server and power the sensors. Communication is established instantly and signal level is displayed in real time.
• 3. View the Modbus map — The Modbus register table is visible from the receiver’s server so integrators can check addresses and values, reducing addressing errors.
• 4. Connect to your BMS/PLC — Physically connect the receiver to your PLC or BMS; the controller can immediately query Modbus registers to retrieve sensor data.
