The difference between industrial Ethernet switches and general switches

The difference between industrial Ethernet switches and general switches:

In the network developed today, the switch is used by many friends who need to use the network, can achieve a network of more than one computer common.But what is the industrial Ethernet switch, very inertial thinking is the industrial switch, so what is the difference between industrial Ethernet switch and general switch?

Industrial Ethernet switch:

Industrial Ethernet switch, which is used in the field of industrial control Ethernet switch equipment, due to the use of open network standards, its wide application;Can adapt to low temperature and high temperature, strong electromagnetic interference resistance, salt fog resistance, strong earthquake resistance.

Ethernet switches use a transparent and unified TCP/IP protocol, and Ethernet has become the main communication standard in the field of industrial control.

It is mainly used in industrial control automation, road traffic control automation, building automatic control system, mine automatic control system, oil field control automation, hydropower station control automation, power system control automation, computer room monitoring system.

Product features

  1. High performance Ethernet switch technology to ensure Ethernet communication speed
  2. IEEE802.3/802.3 d / 802.3 u / 802.3 x, storage transformation exchange way
  3. It has the function of suppressing broadcast storm, warning information of port link and relay output function of power fault information
  4. Use 12~48VDC double redundant power supply
  5. Operating temperature: -10~+60℃ (normal temperature), -40~+85℃ (wide temperature)
  6. The use of metal shell, generally aluminum shell.Protection level IP40.
  7. 10base-t / 100base-tx adaptive Ethernet interface, MDI/ mdi-x, full duplex/half duplex adaptive

Industrial switch Ethernet advantage:

Industrial Ethernet switches are closer to industrial network communication in terms of functions, such as interconnectivity with various fieldbuses, equipment redundancy and real-time equipment, etc.The difference in performance is mainly reflected in the different parameters of the external environment.In addition to a lot of particularly harsh environments such as coal mines and ships, the industrial environment also has special requirements in terms of EMI (electromagnetic compatibility), temperature, humidity and dust control.The influence of temperature on industrial network equipment is the most extensive.

(Ethernet) general switch:

Ethernet switch is a data transfer switch based on Ethernet, which USES local area network (LAN) sharing bus transmission media.Ethernet switches are structured so that each port is directly connected to the host and typically works in full duplex mode.A switch can connect many pairs of ports at once, allowing each pair of communicating hosts to transmit data without conflict as if it were an exclusive communication medium.

Ethernet switches are the most widely used, inexpensive and complete class.Therefore, the application field is very wide, in large and small LAN can see their traces.Ethernet switches typically have several to dozens of ports, essentially a multi-port bridge.In addition, it can have different port rates and work modes, such as 10M and 100M bandwidth, half duplex, full duplex and adaptive working mode.

Characteristics 

  1. Each port of an Ethernet switch is directly connected to the host and generally operates in full duplex mode.
  2. The switch can connect many pairs of ports at the same time, so that each pair of hosts communicating with each other can transfer data without conflicts like exclusive communication media.
  3. Shared transmission media bandwidth. For common 10 Mb/s Shared Ethernet, if there are N users, the average bandwidth occupied by each user is only one of the N of the total bandwidth (10 Mb/s).
