What is an Industrial Ethernet Switch? Ethernet switch is a common network device, and industrial Ethernet switch is an Ethernet switch with industrial-grade characteristics, which plays a vital role in rail transit, intelligent manufacturing, and industrial automation control systems. With the continuous improvement of industrial automation, the requirements for industrial Ethernet switches are also increasing. This article will introduce industrial Ethernet switches in detail from the principles, advantages, characteristics, applications, and future development trends of industrial switches.
How an Industrial Ethernet switch works
Industrial Ethernet switches connect with a variety of industrial devices such as sensors, PLCs, human-machine interfaces, and more through physical interfaces. When communication between industrial devices is required, they send the packets to the industrial Ethernet switch, which identifies the destination of the packet based on the MAC address and forwards the packet to the appropriate port.
When transmitting data, industrial Ethernet switches can realize the fast transmission of data packets through various technologies such as store-and-forward, pass-through forwarding, and fragment-free forwarding. In the forwarding process, the industrial switch adopts technologies such as flow control, congestion control, and mispacket retransmission to ensure the stability and reliability of data transmission. And by supporting various redundancy technologies and industrial protocols, the reliability, stability and compatibility of the network are improved, so as to adapt to the data communication needs of various industrial sites.

What are the advantages of Industrial Ethernet switches over standard Ethernet switches?
Compared to standard Ethernet switches, industrial Ethernet switches offer several advantages:
- Strong resistance to high and low temperatures: The most basic feature of the industrial switch is its industrial-grade characteristics, such as its wide temperature design, which can generally work normally in the temperature range of -40°C to 75°C, coupled with the rugged IP40 protection design, which can make it adapt to the harsh working environment.
- Stronger anti-interference ability: Industrial field environments often have strong electromagnetic interference, and industrial Ethernet switches use anti-interference technology to effectively resist these interferences, thus ensuring reliable data transmission.
- Higher reliability and stability: Industrial Ethernet switches use a variety of redundancy technologies, such as ring network redundancy, link redundancy, equipment redundancy, power supply redundancy, etc., which can achieve fast automatic switching in the event of network failure or equipment failure, thereby improving the reliability and stability of the network.
- Support a wider range of industrial protocols: Industrial Ethernet switches not only support standard Ethernet protocols, but also support various industrial protocols, such as Modbus, PROFINET, EtherNet/IP, etc., which can meet various data communication needs in industrial sites.
- Higher security: Industrial Ethernet switches adopt various security measures, such as VLAN isolation, MAC address filtering, IP address filtering, data encryption, etc., which can effectively protect the security of industrial field networks and prevent unauthorized access and data leakage.
In short, compared with standard Ethernet switches, industrial Ethernet switches have higher reliability, stability, security, and compatibility in the fields of intelligent transportation and industrial automation, and can better meet various data communication needs in industrial sites.
