What Is an Industrial Gateway?

A gateway that is specifically tailored and created for industrial settings and IoT applications is known as an industrial gateway. Industrial gateways connect local network resources with remote assets situated on another network or in the cloud, just like any gateway operating at the network’s edge.

With the aim of absorbing data created on the factory floor and transmitting it upstream for additional processing, it is often implemented on devices on the factory floor, production equipment, and sensors close to the edge. Industrial gateways can connect systems using a variety of network protocols, just as these edge gateways, and frequently include on-board processing to protect, filter, and manage complicated data flows.

Industrial IoT gateway devices differ from other gateways in that they are built for harsh and isolated situations and require little in the way of physical maintenance and engagement. Environments that call for industrial-grade gateways include shop and factory floors, cars and transportation, and exterior places like transmission towers and rail yards.

Fanless cooling and ventless chassis designs reduce wear brought on by contact with dust and other contaminants while getting rid of the moving elements that are most likely to break down.

Industrial Gateways Network Type

The categories of IIoT gateways by network type include:

Ethernet Networks

Industrial gateways often handle Ethernet networks, including regular Ethernet (10/100/1000 Mbps, for example) and industrial Ethernet protocols like EtherNet/IP, PROFINET, Modbus TCP, and others. In industrial contexts, Ethernet networks provide quick and dependable device and system connectivity. The Dusun DSGW-080 Industrial Ethernet Gateway offers these physical interfaces to facilitate various connectivity options and enable integration with industrial devices and systems. It includes:

  • Ethernet Ports: It has two 10/100 Mbps Ethernet ports, allowing for wired network connectivity.
  • Serial Ports: The gateway features two serial ports, including one RS-485 port and one RS-232 port. These ports enable communication with legacy devices that utilize serial protocols.
  • USB Ports: There are two USB 2.0 ports available for connecting peripheral devices or for additional expansion.

Fieldbus Networks

Systems for industrial automation and control often employ fieldbus networks. Different fieldbus protocols, including DeviceNet, CANopen, PROFIBUS, FOUNDATION Fieldbus, and others, may be supported via industrial gateways. They make it possible for devices that make use of fieldbus communication to be connected and integrated.

Virtual Private Networks (VPNs)

Some commercial ports come with VPNs already built in. VPNs create secure, protected links over public or private networks. This lets industrial devices and systems join and talk to each other securely from afar. VPNs add an extra layer of security to make sure that data sent through the route is safe.

Features of Industrial Gateways

There are a number of features exclusive to industrial gateways that make them ideal for use in factories.

Industrial Protocols Support

Industrial gateways offer support for a wide range of industrial protocols such as Modbus, Profibus, EtherNet/IP, PROFINET, CANopen, and more. This capability allows for seamless integration with various industrial devices, smart sensors, and control systems, regardless of the communication protocols they use. It promotes interoperability and facilitates the exchange of data between disparate systems.

Robust Design

Industrial gateways are designed to withstand the challenging conditions found in industrial environments. They are typically built with rugged enclosures, high-quality components, and have high ingress protection (IP) ratings. These features enable them to withstand dust, moisture, temperature extremes, vibrations, and other environmental factors commonly encountered in industrial settings. The robust design ensures reliable performance and longevity even in demanding operating conditions.

Industrial-grade Security

In industrial settings, security is crucial for protecting sensitive data and vital infrastructure. Industrial gateways have strong security features including firewall capability, data encryption, and safe authentication procedures. The confidentiality, integrity, and availability of data communicated over the gateway are ensured by these security measures, which guard against unauthorized access, data breaches, and cyber threats.

Adaptability and Expansion

The expanding requirements of industrial networks are catered for by industrial gateways. By allowing several connections to run simultaneously and having the capacity to manage an increasing number of connected devices, they provide scalability. Additionally, a lot of gateways provide options for expandability via modular design or extra ports, making it simple for enterprises to scale up their infrastructure as their needs change.

Coordinated Management

Industrial gateways sometimes include web-based administration interfaces or centralized management software, which enables administrators to setup, watch over, and administer several gates from a single interface. This unified administration speeds configuration changes, makes it easier to monitor device condition and performance, and gives a thorough picture of the industrial infrastructure. It also makes network management jobs simpler. It improves operational effectiveness and enables administrators to act quickly in response to any problems or abnormalities.
