The BL118 is more than a traditional communication gateway. It integrates protocol conversion, edge computing, local logic control, and cloud connectivity into a single compact device. Positioned at the edge of industrial networks, BL118 enables seamless data exchange between PLCs, sensors, meters, SCADA/MES systems, and cloud platforms, forming a solid foundation for digital industrial automation.
With built-in Node-RED, users can easily design and deploy data processing logic, alarms, and control strategies through a visual, drag-and-drop interface—significantly reducing engineering time and development cost.
Industrial sites often operate with equipment from multiple vendors and different generations. BL118 is built to handle this complexity by supporting a wide range of industrial protocols, including:
Modbus RTU / Modbus TCP
CAN
BACnet MS/TP and BACnet/IP
DL/T645 power meter protocol
OPC UA (Server)
MQTT, HTTP, WebSocket
This broad compatibility allows BL118 to act as a universal integration hub, collecting data from diverse field devices and delivering standardized data to upper-level systems without modifying existing PLC programs.
Equipped with a pre-installed Node-RED runtime, BL118 enables powerful edge-side processing capabilities:
Local data filtering, aggregation, and transformation
Alarm and event logic execution at the edge
Protocol mapping and data normalization
Offline operation with local decision-making
By processing data locally, BL118 reduces network load, minimizes latency, and improves system reliability—especially in distributed or remote industrial environments.
BL118 provides secure and flexible connectivity to both on-premise SCADA/MES systems and cloud platforms, including AWS IoT, Huawei Cloud IoT, and other industrial IoT platforms. Using MQTT, OPC UA, or HTTP/WebSocket, real-time industrial data can be transmitted securely for visualization, analytics, and remote monitoring.
This makes BL118 an ideal edge device for applications such as:
Smart factories
Energy management systems
Water and wastewater treatment
Distributed automation and remote stations
Designed for harsh industrial environments, BL118 features:
Industrial-grade components with wide temperature tolerance
EMC and EMI protection
Independent hardware watchdog for long-term stability
Wide power input range (12–36 VDC)
Rugged aluminum enclosure for DIN-rail installation
These features ensure 24/7 stable operation, even in demanding industrial conditions.
With modular X-series and Y-series I/O boards, BL118 supports a wide range of signal types, including DI, DO, AI, AO, RTD, thermocouples, and serial communication. This flexibility allows BL118 to function not only as a gateway, but also as a distributed I/O controller for localized automation tasks.
BL118 integrates BLRAT remote access technology, enabling secure remote configuration, diagnostics, and maintenance. This significantly reduces on-site service requirements and improves response time—an essential advantage for large-scale or geographically distributed industrial projects.
The BL118 Node-RED Edge Gateway delivers a powerful combination of connectivity, intelligence, and reliability for modern industrial automation. By unifying field devices, control systems, and cloud platforms at the edge, BL118 helps industries accelerate digital transformation, optimize operations, and build scalable automation architectures with confidence.
