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

Quick Start​

  1. Run IoTGateway and configure transport settings
  2. Register on ThingsCloud console, create a project
  3. Create gateway and sub-device types
  4. Create devices and bind them
  5. Copy gateway Token and AccessKey to IoTGateway
  6. Configure dashboards and mobile apps

Overall Experience: Very Smooth​

Implementation​

The custom target overrides the Write method, serializes log events to JSON with both default and custom fields, and publishes to an MQTT topic.

Industrial IoT systems span ERP, MES, SCADA, WCS, edge gateways, and devices. When issues arise, APM systems help trace problems across the full stack.

OpenTelemetry​

OpenTelemetry is a vendor-neutral protocol standard from Google and Microsoft, unifying OpenTracing and OpenCensus. It supports 11 languages including .NET, and can collect metrics, logs, and traces.

Jaeger & Seq​

Jaeger provides distributed tracing storage and query. Seq serves as the log platform with SQL query and chart support.
