BL118 Node-RED Gateway is an industrial edge computing gateway with Node-RED V4.0.0 pre-installed. It supports 30+ industrial protocols including Modbus RTU/TCP, Siemens S7 PLC, Mitsubishi FX, BACnet, OPC UA, and MQTT. No coding required — simply drag and drop nodes to collect data from PLCs and sensors, then forward to any cloud platform. With wide temperature support (-45°C to +80°C), flexible I/O expansion, and built-in BLRAT remote maintenance.
BL118 is a professional industrial IoT gateway that comes with Node-RED V4.0.0 pre-installed. As a complete edge computing gateway solution, it enables drag-and-drop IIoT application development without coding. Connect PLCs, Modbus devices, and industrial sensors to any cloud platform in minutes.
Why BL118 Node-RED Gateway is the Right Tool for IIoT Integration
Too Much Coding for Data Integration
Node-RED visual programming eliminates thousands of lines of code. As a drag-and-drop industrial IoT gateway, BL118 requires no embedded C or Python programming — just connect nodes visually.
Incompatible Industrial Protocols
This industrial edge gateway comes pre-installed with 30+ protocol nodes including Modbus RTU/TCP, Siemens S7 PLC, Mitsubishi FX, BACnet IP/MS/TP, OPC UA, and DL/T645.
Complex Cloud Integration
One-click MQTT, HTTP, and WebSocket nodes. The BL118 Node-RED gateway includes ready-to-use templates for Huawei Cloud, AWS IoT, Alibaba Cloud, and ThingsBoard.
Build IIoT Applications Without Writing Code Using Node-RED
Node-RED is a flow-based development tool that lets you connect devices, industrial protocols, and cloud platforms using drag-and-drop nodes. With the BL118 Node-RED industrial gateway, changes take effect instantly with one click of "Deploy".
5000+ Pre-built Nodes
Access thousands of community-contributed nodes for databases, analytics, notifications, and custom logic in this industrial IoT edge gateway.
Real-time Debugging
Built-in debug panel shows message flow. Inject nodes simulate Modbus data for testing without real hardware on your Node-RED gateway.
JavaScript Functions
Write custom logic in JavaScript function nodes when you need advanced data processing or conditional routing for industrial automation.
Import/Export Flows
Save your Node-RED flows as JSON files. Share IIoT applications across multiple BL118 gateways or import from the Node-RED library.
5-Minute Modbus TCP to MQTT Example on BL118 Node-RED Gateway:
1 Drag Modbus-Read node → configure Modbus slave IP and register address
2 Drag Function node → add simple data transformation (e.g., msg.payload = msg.payload * 0.1;)
3 Drag MQTT Out node → enter MQTT broker address and topic
4 Connect the nodes → click Deploy
5 Done! Modbus data flows from industrial device to cloud MQTT broker in real time through your Node-RED industrial gateway.
