Classification of Industrial Ethernet Switches

Industrial Switch is industrial Ethernet switch, that is, Ethernet switch equipment applied in industrial control field. Due to the network standard adopted, it has good openness and wide application; It can adapt to low temperature and high temperature, with strong anti electromagnetic interference, anti salt fog and strong seismic resistance. According to different standards, industrial switches can be roughly divided into six categories. Industrial switches have carrier grade performance characteristics and can withstand harsh working environment. Rich product series and flexible port configuration can meet the needs of various industrial fields.

1. Take the consistency of port rate of industrial switch as the standard (mainly for fixed port industrial switch)

(1) Symmetric industrial switch (all ports have the same rate). (2) Asymmetric industrial switches (ports with different rates).

2. Take the structure of industrial switch as the standard

(1) Fixed port industrial switch (fixed port is cheap, but the number of ports provided by itself is limited).

(2) Modular industrial switches (with greater flexibility and scalability, the latter is often used in core industrial switches or converged industrial switches).

3. Based on transmission rate

(1) 100M Ethernet industrial switch (all ports are 100m, with 2-4 1000m ports or slots, and its interface types include 100base TX twisted pair port and 100base FX optical fiber port).

(2) Gigabit Ethernet industrial switch (the interface type of Gigabit Ethernet industrial switch includes: 1000BASE-T twisted pair port 1000base SX optical fiber port 1000base_lx optical fiber port 1000 Mbps Photoshop GBIC slot 1000Mbps SFP slot).

(3) 10 Gigabit Ethernet industrial switch (10 Gigabit Ethernet industrial switch is mainly provided in the form of 10Gbps module and slot).

4. based on Job protocol layer

(1) 2 Layer industrial switch (mainly used to realize fast information exchange between hosts in LAN).

(2) 3 layer industrial switch (mainly used for line speed forwarding between VLANs).

(3) 4 layer industrial switch (provides optimized configuration of network application resources, and realizes quality of service, load balancing and security control).

5. Whether the industrial switch can be managed as a standard (see whether the industrial switch has a console port)

(1) Intelligent industrial switch, also known as network managed industrial switch. (2) Fool industrial switch, also known as non network unmanaged industrial switch.

6. The network location of industrial switch is not standard 

(1) Industrial switch is also called industrial Ethernet switch, that is, Ethernet switch used in industrial control field. Ethernet has become the main communication standard in the field of industrial control due to its good openness, wide application, low price, and the use of transparent and unified tcp/ip protocol. Access layer industrial switch (within 100 information points). Fixed deployment industrial switch, 16-48 100M Ethernet interfaces, used for network access of ordinary computers, 2-4 1000m ports or slots, used for Gigabit connection with the upper switching surface.

(2) Convergence layer industrial switch (supporting 300 information points and below). All industrial switches in the access layer are 1000m network interfaces with network management functions. At the same time, they have up to 10 10g ports or slots, which are used to realize Gigabit connection with the upper switching surface.

(3) Core industrial switch (supporting 500 information points and above).

In addition, industrial switches can be classified into many other categories, such as rail type, rack type, embedded type, etc. different environments and industries can choose appropriate industrial switches to maximize work efficiency.
