Usage of Industrial Ethernet Switches

Understand the Industrial Ethernet Switch

Industrial Ethernet switches are specially designed to meet the needs of flexible and changeable industrial applications, providing a cost-effective industrial Ethernet communication solution.Industrial Ethernet switches , as our widely used LAN hardware devices, have always been familiar to everyone.Its popularity is actually due to the widespread use of Ethernet.As the mainstream device of Ethernet today, this device exists in almost all LANs.

The industrial Ethernet switch is a switch that transmits data based on Ethernet, and Ethernet adopts a local area network of shared bus transmission media.The structure of the Ethernet switch is that each port is directly connected to the host, and generally works in full-duplex mode.The switch can connect many pairs of ports at the same time, so that each pair of hosts that communicate with each other can transmit data without conflict as if they monopolize the communication medium.Looking at the following topology, you will find that in the case of star topology, there must be a switch in the Ethernet, because all the hosts are connected to the industrial Ethernet switch centrally using cables so that they can be connected to each other .

The Physical Characteristics and Use of Industrial Ethernet Switches

The physical characteristics of an industrial Ethernet switch refer to the appearance characteristics, physical connection characteristics, port configuration, base type, expansion capability, stacking capability and indicator light settings provided by the switch, reflecting the basic situation of the switch.

Switching technology is a switching product with the characteristics of simplification, low price, high performance and high port density.It embodies the complex switching technology of bridging technology in the second layer of the OSI reference model.The difference from the bridge is that the forwarding delay of the switch is very small, which is close to the performance of a single LAN, and far exceeds the forwarding performance between ordinary bridged Internet networks.Switching technology allows shared and dedicated LAN segments to adjust bandwidth to alleviate bottlenecks in information flow between LANs.Now there are switching products of Ethernet, Fast Ethernet, FDDI and ATM technology.

Utilizing a specially designed integrated circuit allows the switch to forward information in parallel at all ports at line rate, providing much higher operational performance than traditional bridges.ASIC technology enables switches to operate at these levels with more ports at a lower cost than traditional bridges.

Industrial Ethernet switches are widely used.In terms of industrial applications, they are mainly used in: coal mine safety, rail transit, factory automation, water treatment systems, urban security, etc.
