β–‡ 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.

β–‡ 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 of devices and protocols. Based on this, a tool software was born specifically for this purpose!

β–‡ What Can It Do?

βœ” Protocol Conversion

The IoT gateway helps you shield the differences in protocols from different eras and manufacturers, converting them into commonly used IoT protocols (such as MQTT, HTTP, etc.) to output to the platform, allowing you to receive data directly through subscriptions, giving you more time to focus on business construction on the platform.

βœ” Security

The gateway provides a device connection pool, significantly reducing the number of devices connected to the internet.

It can provide a unified verification and authorization mechanism to prevent external business systems from unauthorized control of IoT devices.

βœ” Easy Expansion

The IoT gateway can manage and control highly decentralized industrial devices, addressing the challenges of increasing device numbers and continuous access of different protocol devices in the future.

βœ” Data Filtering

Devices generate massive amounts of data, and sending all of it to the platform would be overwhelming; transmission and storage would incur high costs. Moreover, in our current business system, only data that changes will lead to business changes. Therefore, pushing only the changed values is meaningful.
