▇ What is an Industrial IoT Gateway?
An industrial IoT gateway is a hardware device or software program that connects local devices in industrial scenarios (such as PLCs, barcode scanners, robots, CNC machine tools, etc.) with remote business systems (such as SCADA systems, MES systems, etc.). All data communication between terminal devices and remote business systems is achieved through the industrial IoT gateway.
▇ Why Do We Need an Industrial IoT Gateway?
Because in the automotive industry, our business systems (MES) frequently interact with on-site devices. However, the on-site situation can be very complex, requiring integration with many types and protocols of devices. Based on this, a tool software was born specifically to handle this task!
▇ What Can It Do?
✔ Protocol Conversion
The IoT gateway will help you shield the differences in protocols from different eras and manufacturers, converting them into commonly used IoT protocols (such as MQTT, HTTP, etc.) for output to the platform. You can directly receive data by subscribing, allowing you more time to focus on business development on the platform.
✔ Security
The gateway will provide a device connection pool, significantly reducing the number of devices connected to the Internet.
It can provide a unified authentication and authorization mechanism to prevent external business systems from unauthorized control of IoT devices.
✔ Easy to Expand
The IoT gateway can manage and control highly decentralized industrial devices, addressing the challenges of increasing device numbers and continuous access of devices with different protocols in the future.
✔ Data Filtering
Devices generate massive amounts of data, and if all are sent to the platform, it would certainly be overwhelming. Transmission and storage come with high costs, and in our current business systems, only data that changes will bring about business changes. Therefore, pushing only the changed values is meaningful.
▇ Data Flow
Finally, let’s step by step create an IoT gateway from 0 to 1.
