Introduction to the role of industrial switches

With the gradual maturity of automation and the rise with the large-scale use of industrial Ethernet and the establishment of large-scale industrial control networks, industrial switches, namely industrial Ethernet switches, are also widely used in the field of industrial control. Today we will take a look at the role of industrial switches .

The role of industrial switches:

 Industrial Ethernet switches are mainly used for real-time Ethernet data transmission in complex industrial environments. When Ethernet is designed, due to its use of Carrier Sense Multiplexing Collision Detection (CSMA/CD mechanism), its reliability is greatly reduced when it is applied in a complex industrial environment, which makes Ethernet unusable.

The industrial Ethernet switch adopts the storage conversion and exchange method, and at the same time improves the Ethernet communication speed, and the built-in intelligent alarm design monitors the network operation status, so that the reliable and stable operation of the Ethernet can be ensured in the harsh and dangerous industrial environment.

Industrial Ethernet Switch

The environment of the industrial site is worse than the ordinary environment, at least in terms of vibration, humidity, and temperature. The ordinary switch is not designed to withstand the various situations that appear in the industrial environment, and the ordinary switch cannot be long. Working in this harsh environment often leads to failures and increases maintenance costs. It is generally not recommended to use commercial switches in industrial environments. In order to enable switches to be used in such harsh environments, the production can adapt to this The reliability of environmental switches and industrial-grade switches includes power failure, port interruption, relay output alarm, redundant dual DC power input, active circuit protection, automatic circuit breaker protection for overvoltage and undervoltage.

(1) Function: Industrial Ethernet switches are closer to industrial network communication, such as the interconnection of various field buses, the redundancy of equipment, and the real-time requirements of equipment.

(2) Performance: It is mainly reflected in the different parameters applicable to the external environment. In addition to the particularly harsh environment, the industrial environment also requires EMI electromagnetic compatibility, temperature, humidity, dust resistance, etc., especially the impact of temperature on industrial network equipment Is the most extensive.
