What is IoTGateway​

A cross-platform IoT gateway with B/S architecture built on .NET, serving as a bridge between southbound devices (PLCs, CNCs, robots, etc.) and northbound platforms (IoT platforms, SCADA, MES).

Data Flow​

  1. Device → Cloud (Data Collection)
  2. Cloud → Device (Reverse Control)
  3. Device → Device (M2M)

Key Features​

  • Cross-platform: Windows/Linux, bare metal or Docker, x86/ARM
  • Built-in drivers: Modbus, Siemens, Mitsubishi, Omron, Allen-Bradley, MTConnect CNC, and custom driver SDK
  • Calculation expressions: Dynamic C# scripting for data transformation
  • MQTT Server: Built-in for business system integration
  • OPC UA Server: For industrial control system data access
  • Digital Twin 3D: Three.js demo with real-time MQTT-WebSocket updates
  • Multi-platform integration: IoTSharp, ThingsBoard, ThingsCloud, ThingsPanel
  • Online SCADA: Seamless visualization integration

Why You Need an IoT Gateway​

  • Protocol Conversion: Abstract protocol differences
  • Security: Gateway as first line of defense
  • Scalability: Manage complex changes without full-system upgrades
  • Data Preprocessing: Ratios, offsets, edge computing
  • Data Filtering: Only transmit meaningful changes
  • Data Aggregation: Compute across devices before sending
  • Data Caching: Buffer during network disconnections
