As we all know, industrial switches are industrial equipment designed to meet the needs of flexible and variable industrial applications. It provides a cost-effective industrial Ethernet communication solution. The networking method is more focused on the loop design, so the use of ring network industrial switches is very popular. Among them, the ring has the difference between single ring and multi-ring. At the same time, there are private loop protocols designed by various industrial switch manufacturers based on STP and RSTP, such as FRP ring and turbo ring. The following industrial PoE manufacturer will introduce the core technical advantages used by industrial switches.
Ring network industrial switch products
Industrial switches have the following advantages:
(1) Zero self-healing ring network technology to achieve high reliability and integrity of data transmission
Prior to this, the fastest self-healing time for global industrial switches was 20 milliseconds. However, no matter how short the self-healing time of the ring network fault is, the data packets will be lost during the switchover, which cannot be tolerated at the control command layer. Zero self-healing has undoubtedly achieved breakthroughs in existing technologies, ensuring high reliability and integrity of data.
Industrial switches use two-way data flow to ensure that when a network fails, there is always one direction to reach the destination, ensuring uninterrupted control data.
(2) Bus-type network, realize the integration of network and wire
The bus-type network allows users to customize the controlled device. By treating the same virtual Mac terminal as the same device, the switch treats the controlled device as the same device, enabling these devices to communicate with each other and share information, ensuring the linkage of control.

PoE switch supports multiple bus protocols and I / O interfaces to network the bus data. Instead of the non-traditional point-to-point mode, the network and bus resource utilization is maximized. In addition, flexible network configuration can be realized, and field devices such as meters and industrial cameras can be directly connected, allowing PLCs to be connected to further I / O devices, greatly reducing the number of PLCs in the entire system and significantly reducing the cost of system integration. . In addition, industrial switches can be integrated into network monitoring software to monitor node status in real time through Web and SNMP OPC Server, and are equipped with a fault alarm function to facilitate remote maintenance and management.
(3) Fast and real-time
Industrial switches have data priority features, allowing users to customize certain devices as fast data devices. When fast data appears in the ring network, ordinary data will make way for fast data. It avoids the situation that the traditional switch cannot be applied to the control command layer because the data delay is too large.
(4) Independent controllable design
Outdoor industrial PoE injector belongs to the self-developed products and has the intellectual property rights of the products. Its core software / hardware, products, and services are all independently controllable, which basically guarantees that there are no malicious backdoors and that they can be continuously improved or patched.
