Anyone who has worked in the industrial field will know that industrial switches are called industrial Ethernet switches. Industrial Ethernet switches are what we often call industrial switches. Industrial switches are designed to meet the needs of flexible industrial applications. Equipment, it provides a cost-effective industrial Ethernet communication solution. Therefore, industrial switches are very popular in the industry. Among them, the loop has the difference between single loop and multiple loops. At the same time, there are also private loop protocols designed by various industrial switch manufacturers based on STP and RSTP. So what are the core technical advantages of industrial switches? Next, let's follow the editor of Feichang Technology to learn more about it!
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 occur during the switching period, which cannot be tolerated at the control command layer. And zero self-healing undoubtedly achieved a breakthrough in existing technologies, ensuring high reliability and integrity of data.
Industrial switches use 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. Bus-type network, which 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, making these devices mutually exclusive Intercommunication and information sharing ensure the linkage of control.
Industrial switches support multiple 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. In turn, 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 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 belong to independent research and development products and have product intellectual property rights. Its core software/hardware, products, and services are all independently and controllable, which basically guarantees that there is no malicious backdoor and can continue to improve or repair vulnerabilities.
