Working principle of Industrial Ethernet Switch

Industrial Ethernet Switches are connected to various industrial devices, such as sensors, through physical interfaces PLC、 Human computer interface, etc. When industrial equipment needs to communicate with each other, they send data packets to Industrial Ethernet Switches, which identify the destination of the packets based on their MAC addresses and forward them to the corresponding ports.

Industrial Ethernet Switches can achieve fast packet transmission through various technologies such as store and forward, pass through forwarding, and fragment free forwarding when transmitting data. During the forwarding process, industrial switches adopt flow control, congestion control, error packet retransmission and other technologies to ensure stable and reliable data transmission. By supporting various redundant technologies and industrial protocols, the reliability, stability, and compatibility of the network have been improved to meet the data communication needs of various industrial sites.

In addition, the sturdy IP40 protection design can make them adapt to harsh working environments.

2. Stronger anti-interference ability: Industrial site environments usually have strong electromagnetic interference, and industrial Ethernet switches use anti-interference technology to effectively resist these interferences, thereby ensuring reliable data transmission.

3. Higher reliability and stability: Industrial Ethernet Switches adopt various redundancy technologies, such as ring network redundancy, link redundancy, equipment redundancy, power redundancy, etc., which can achieve fast automatic switching in case of network or equipment failure, thereby improving the reliability and stability of the network.

4. Support for a wider range of industrial protocols: Industrial Ethernet Switches not only support standard Ethernet protocols, but also various industrial protocols such as Modbus, PROFINET, EtherNetIP, etc., which can meet the various data communication needs of industrial sites.

5. 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 site networks and prevent unauthorized access and data leakage.

In summary, compared to standard Ethernet switches, Industrial Ethernet Switches have higher reliability, stability, security, and compatibility in the fields of smart transportation and industrial automation, and can better meet various data communication needs in industrial sites.
