What is an industrial gateway

Industrial gateway refers to the device that connects different devices and networks in industrial automation systems. It plays a key role in the Industrial Internet of Things (IIoT) and smart manufacturing. The main function of the industrial gateway is to realize conversion between different communication protocols, so that devices from different manufacturers and different types can communicate with each other and work together.


Equipment in industrial automation systems often use a variety of different communication protocols and standards, such as Modbus, Profibus, EtherNet/IP, etc. Industrial gateways can bridge communications between these different protocols to achieve interconnection and interoperability between devices. In addition, the industrial gateway can also realize data collection, processing and forwarding, and support real-time monitoring and remote management of data.

Industrial gateways are usually designed taking into account the harsh conditions of industrial environments, such as temperature changes, humidity, electromagnetic interference, etc., so they usually have industrial-grade durability and stability.

Industrial gateway functions

Industrial gateways improve the overall efficiency and intelligence level of industrial automation systems by promoting collaborative work among devices.

Specifically, the functions and roles of industrial gateways include:

Communication protocol conversion: There are multiple communication protocols and standards in industrial automation systems, and devices usually use specific protocols. Industrial gateways can realize conversion between different protocols, allowing different devices to understand and exchange information with each other.

Data bridging: Industrial gateways can bridge data from different devices to realize data transmission and sharing. This helps consolidate information from individual devices to form a comprehensive view of the data.

Data processing: Industrial gateways can perform data processing and analysis, including data filtering, aggregation and format conversion. This helps extract useful information, enabling real-time monitoring and remote management.

Equipment management and monitoring: Industrial gateways enable equipment to be managed and monitored over the network. This includes capabilities such as remote diagnostics, configuring device parameters and performing firmware updates.

Security: Industrial gateways often have security features that protect industrial systems from potential cyber threats. This includes security measures such as data encryption, authentication and access control.

Appearance characteristics of industrial gateways

The appearance design of the industrial gateway focuses on durability, stability and adaptability to the special needs of industrial scenarios. This allows them to operate reliably in industrial automation systems and connect a variety of equipment. The appearance of industrial gateways can vary depending on the manufacturer and model, but generally share some common characteristics to meet the needs of industrial environments. The following are possible appearance characteristics of a typical industrial gateway:


Rugged Enclosure: Industrial gateways typically feature rugged metal enclosures to withstand the physical challenges of industrial environments, such as vibration, impact, and friction. The casing is usually designed to be dustproof, waterproof or corrosion-proof to ensure long-term stable operation of the equipment.


Heat dissipation structure: Since industrial environments may produce higher temperatures, industrial gateways are usually designed with effective heat dissipation structures, such as heat sinks or fans, to ensure that the equipment can operate effectively under high temperature conditions.


Multiple connection ports: Industrial gateways are usually equipped with multiple connection ports, including various communication interfaces, serial ports, Ethernet ports, and USB interfaces. These interfaces are used to connect different types of devices and support multiple communication protocols.


Indicator lights and displays: Industrial gateways are often equipped with indicator lights to show the status of the device, such as power status, network connection status, and data transmission status. Some industrial gateways may also feature a simple display for local configuration and monitoring.


Wall mounting or DIN rail installation: Industrial gateways are usually designed to be flexibly installed and can be installed on industrial cabinets or equipment through wall mounting or DIN rail mounting.


Comply with industrial standards: To ensure the reliability and safety of equipment in industrial environments, industrial gateways often comply with specific industry standards and certification requirements.

IIoT and Automation Gateways

Industrial Internet of Things (IIoT) and automation gateways play an important role in the industrial sector.

Industrial Internet of Things (IIoT):

The Industrial Internet of Things refers to connecting industrial equipment and systems to the Internet to achieve data exchange and real-time monitoring, thereby improving production efficiency and effectiveness. It enables industrial equipment to collect and share data through sensors, equipment and network connections, supporting remote monitoring and intelligent decision-making. The goal of IIoT is to interconnect equipment, optimize production processes, and provide insights through data analysis to improve operations and maintenance.

Automation gateway:

Automation gateway is a key component that connects different devices and systems, and it plays a bridge role in the automation system. Automation gateways can connect devices with different communication protocols to achieve data integration and exchange. It allows communication between various automation equipment, sensors and control systems, thereby enabling the entire system to work together. Automation gateways may also involve data processing, security features and remote monitoring to meet the needs of the automation system.


IIoT focuses on the interconnection and data utilization of industrial equipment, and the automation gateway is a key component to achieve this interconnection. It supports the realization of industrial automation by connecting and coordinating different equipment and systems. The two jointly promote digital transformation and intelligent development in the industrial field.

Network types of industrial gateways

Industrial gateways are often able to support multiple network types to meet the connectivity needs between different devices and systems. The following are some common industrial gateway network types:


Ethernet: Industrial gateways usually support Ethernet connections, including standard Ethernet and industrial Ethernet (such as Ethernet/IP, Profinet, etc.). Ethernet is commonly used for high-speed data transmission and connecting devices to local area networks (LANs).


Serial port: Serial ports are often used for communication in industrial equipment, so industrial gateways are usually equipped with serial ports, such as RS-232, RS-485, etc., to support connection with serial devices.


Wi-Fi: Some industrial gateways support Wi-Fi connectivity, allowing devices to connect to industrial automation systems over wireless networks.


Bluetooth: Bluetooth connection is suitable for some low-power devices and short-distance communication, and some industrial gateways may support Bluetooth connection.


Mobile Cellular Gateway: A mobile cellular gateway is a device that is primarily used to connect mobile devices to the cellular network. It plays an important role in mobile communications, acting as a bridge between mobile devices and cellular base stations. The mobile cellular gateway is responsible for processing requests from mobile devices and forwarding them to the cellular network, and is also responsible for delivering data returned from the cellular network to the mobile device.
