Industrial switches are specifically designed to meet the needs of flexible and changeable industrial applications and provide a cost-effective industrial Ethernet communication solution.And its networking mode is more focused on loop design. The ring has the difference between single ring and multiple ring. At the same time, there are private ring protocols designed by various manufacturers based on STP and RSTP, such as FRP ring, turbo ring, etc.

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 failure is, the loss of data packets will inevitably result in the switching period, which cannot be tolerated at the control command layer. And zero self-healing undoubtedly achieved a breakthrough in existing technologies to ensure high reliability and integrity of data. The switch uses two-way data flow to ensure that when the network fails, there is always one direction to reach the destination, ensuring uninterrupted control data.

(2) The bus-type network realizes the integration of network and line:

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, sharing information, and ensuring the linkage of control .

The switch supports a variety of bus protocols and I/O interfaces to realize the networking of bus data. Instead of the non-traditional point-to-point mode, maximize the resource utilization of the network and bus. Furthermore, flexible network configuration can be realized, which can be directly connected to field devices such as meters and industrial cameras, allowing PLCs to be connected to I/O devices farther away, 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 through Web and SNMP OPC Server to monitor node status in real time, and are equipped with fault alarm functions 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 traditional switches cannot be applied to the control command layer due to excessive data delay.

(4) Independent and controllable design:

Industrial switches are self-developed products and have product intellectual property rights. Its core software/hardware, products, and services are all independently and controllable, basically ensuring that there is no malicious backdoor and that it can be continuously improved or patched.
