DRAGINO LoRaWAN Gateway with Modbus RS485, Ethernet and 4G

What Is the DRAGINO LoRaWAN Gateway with Modbus RS485, Ethernet and 4G (MS48-LR)?

The Dragino MS48-LR is an open-source LoRaWAN to Modbus Gateway designed to bridge wireless LoRaWAN sensor networks with traditional industrial automation and control systems.

The gateway enables LoRaWAN sensors and end devices to communicate with systems that use Modbus RTU or Modbus TCP. This makes it possible to integrate wireless LoRaWAN measurements into PLCs, SCADA systems, industrial controllers, and other Modbus-compatible applications.

Instead of requiring a separate LoRaWAN gateway and an additional conversion device, the MS48-LR combines LoRaWAN connectivity and Modbus conversion in a single platform. It can operate as a Modbus RS485-RTU slave, converting LoRaWAN sensor uplink data into Modbus data and writing the information into registers accessible through the Modbus network.

The MS48-LR also includes a built-in LoRaWAN server and IoT server, allowing users to connect various LoRaWAN devices directly to the gateway. The platform supports multiple LoRaWAN connection methods, including Semtech UDP Packet Forwarder, LoRaWAN Basic Station, and ChirpStack Gateway Bridge via MQTT.

For network connectivity, the gateway can use Ethernet, WiFi, or optional 4G cellular communication. This gives system integrators flexibility when deploying the gateway in locations with different network infrastructure requirements.

How Does the MS48-LR Work?

• LoRaWAN sensors collect data
  Wireless LoRaWAN sensors measure parameters such as temperature, humidity, air quality, energy, equipment status, or other application-specific values.
• Sensors transmit data wirelessly
  The LoRaWAN end devices send collected data through the long-range LoRaWAN wireless network.
• MS48-LR receives the data
  The multi-channel LoRaWAN gateway receives the wireless sensor transmissions.
• LoRaWAN data is processed
  The gateway's built-in LoRaWAN and IoT services process the incoming sensor information.
• Data is converted to Modbus
  The MS48-LR maps the LoRaWAN sensor data into Modbus registers. In Modbus slave mode, external systems can read the values through the Modbus interface.
• PLC or SCADA system accesses the data
  A PLC, industrial controller, SCADA system, or other Modbus-compatible device can retrieve the wireless sensor measurements using Modbus RTU or Modbus TCP.
• Data can be connected to IoT applications
  The gateway's built-in software environment, including ChirpStack and Node-RED, provides additional options for data processing, integration, and application development.
