Introduction
With the advent of the Industry 4.0 era, IoT technology is changing our production and lifestyle at an unprecedented speed. This article introduces a cross-platform industrial IoT gateway solution developed based on .NET 6.
The Industrial Internet of Things (IIoT) has become the link between the physical world and the digital world. In this network, the industrial IoT gateway acts like an intelligent traffic officer, directing the busy data traffic between devices and cloud systems.
Next, this article will explain how this solution works, the benefits it brings, and how to easily integrate it into existing production environments.
What is an Industrial IoT Gateway?
An Industrial IoT Gateway (IIoT Gateway) is a hardware device or software program that serves as a bridge between local devices (such as PLCs, barcode scanners, robots, CNC machines, customized upper computers, etc.) and cloud systems (such as IoT platforms, SCADA systems, MES systems, etc.).
All data flowing from devices to the cloud, and data sent from the cloud to devices, is transmitted through the IoT gateway, as shown in the figure below:
Project Introduction
The IoT Gateway solution is built on .NET 6 and supports cross-platform deployment.
Through an intuitive visual configuration interface, you can easily connect to various devices and systems (such as PLCs, barcode scanners, CNC machines, serial devices, upper computers, OPC Server, OPC UA Server, MQTT Server, etc.), achieving bidirectional data communication with ThingsBoard, IoTSharp, or your own IoT platform (MES, SCADA).
It provides a simple driver development interface and supports edge computing capabilities, providing strong support for data processing and analysis.

Documentation
The documentation includes basic, advanced, and hardware information.
-
Any CPU architecture, such as Arm, Arm64, Armv6, X64, X86, LoongArch64 -
Most systems, such as win7-win11, ubuntu, debian, openwrt, and other linux systems, are not limited to the hardware devices I provide.
-
Performance monitoring: CPU, memory, disk, and other host metrics monitoring
-
Hardware interaction: analog quantity collection, relay control, IO, etc.
-
Virtual LAN: Using VPN technology to build a cloud local area network, achieving remote networking of multiple gateway devices, enabling collaborative acquisition and control of device data; supports gateway subordinate unconnected devices to pass through, remote debugging, remote upgrading of PLCs, etc.
-
Virtual remote serial port: capable of passing through serial port capabilities, can pass remote serial devices to the developer’s local machine; developers can complete remote gateway serial device development and debugging locally.
-
