1. The role of industrial switches

Industrial Ethernet switches are mainly used to transmit Ethernet data in real time in complex industrial environments. During the design of Ethernet, due to its use of carrier sense multiplexing conflict detection, it is applied in complex industrial environments, and the reliability is greatly reduced, resulting in Ethernet can not be used. The switching method of industrial Ethernet switch storage conversion can greatly improve the speed of Ethernet communication, and the built-in intelligent alarm design monitors the network operation status to ensure the stable operation of Ethernet in harsh environments to the greatest extent.

2. The difference between industrial switches and ordinary switches

The difference between industrial Ethernet and ordinary switches is mainly reflected in function and performance.

Functional difference: Industrial Ethernet switches are functionally closer to industrial network communication, such as interconnection with various field buses;

The difference in performance: mainly reflected in the adaptation to the different external environmental parameters. In addition to particularly harsh environments such as coal mines and ships, industrial environments also have requirements for electromagnetic compatibility, temperature, and humidity. Among them, temperature has the most extensive influence on industrial equipment.

Whether it is in terms of components, mechanical environment, climatic environment or electromagnetic environment, working voltage, power supply design, installation method, and heat dissipation method, the performance of industrial Ethernet is better than that of ordinary switches.

3. The difference between industrial Ethernet switches and ordinary switches

Generally speaking, switches refer to Ethernet switches. Ethernet switches are generally divided into commercial switches, industrial switches, and home switches.

Commercial switches are generally used in corporate offices and other occasions. They are generally rack-mounted and installed in corporate computer rooms. They usually require high reliability, 24h uninterrupted operation, large bandwidth, and many interfaces. Industrial Ethernet switches are generally used in industrial production occasions. According to the requirements of the occasion, there will be different appearances and various installation forms, requiring waterproof, dustproof, shock resistance, anti-electromagnetic interference and other requirements, and also requires 24h uninterrupted long-term operation.
