The role of industrial switches The difference between industrial switches
First, let's introduce the definition of an industrial switch. Industrial switch is an industrial Ethernet switch, which is used in the field of industrial control. Because the network standard is open, widely used, can adapt to low temperature and high temperature, strong electromagnetic interference resistance, salt spray resistance, strong shock resistance. So, what is the purpose of an industrial switch? What is the difference with ordinary commercial exchange? Next, Xiaobian will take you to have a look!
1. The role of industrial switch:
Industrial Ethernet switches are mainly used for real-time Ethernet data transmission in complex industrial environments. In the design of Ethernet, carrier sense multichannel collision detection (C ** A/CD mechanism) is adopted, which greatly reduces its reliability in complex industrial environment, resulting in the Ethernet cannot be used. Industrial Ethernet switches adopt storage conversion switching to improve Ethernet communication speed. Built-in intelligent alarm design monitors network operation to ensure reliable and stable operation of Ethernet in harsh and dangerous industrial environment.
2. Differences between industrial switches and ordinary switches:
Industrial Ethernet switches differ from ordinary switches mainly in functions and performance.
Functional difference mainly refers to the industrial Ethernet switch is closer to industrial network communication, such as interconnection with various fieldbuses, equipment redundancy, equipment real-time, etc.
The performance difference is mainly reflected in the difference of adapting to the external environment parameters. In addition to coal mines, ships and other harsh environment, industrial environment also many EMI(electromagnetic compatibility, dust protection and other environment has special requirements. Among them, the temperature has the most extensive influence on industrial network equipment.
