Networking Mode of Switch Industrial POE

Industrial Ethernet switches POE are specifically designed to meet the needs of flexible industrial applications, providing a cost-effective industrial Ethernet communications solution. And its networking mode focuses more on loop design. There are single-ring and multi-ring differences in the loop. There are also private loop protocols designed by various vendors based on STP and RSTP, such as RingOn, RingOpen open loop, FRP ring, and turbo ring.

The development of hubs has resulted in a device called unmanaged switch. It enables routing of messages from one port to another, making them more intelligent than hubs. Unmanaged switches can automatically detect the network speed of each network device. In addition, it has a function called "MAC address table", which can recognize and memorize the devices in the network. In other words, if port 2 receives a message with a specific identification code, then the switch will send all messages with that particular identification code to port 2. This intelligence avoids message collisions and improves transmission performance, which is a great improvement compared with the hubs. However, unmanaged switches cannot implement any form of communication detection and redundancy configuration.

The next generation of Ethernet connected devices is the managed switch. Managed switches have more and more complex functions than hubs and unmanaged switches, and they are much more expensive—typically three to four times as large as an unmanaged switch.

Something about Switch Industrial POE

Switch industrial poe is a small part of automation that was not noticed by a few vendors a decade ago. As automation matures and rises with the massive use of industrial Ethernet and the establishment of large industrial control networks, the rich product line cannot be left behind for automation vendors. Speaking of this, everyone will ask, what are the functions of switch industrial poe?

Industrial Ethernet switches are generally designed to meet: 1. Industrial wide temperature design. 2. Level 4 electromagnetic compatibility design. 3. Redundant AC and DC power input. 4. PCB circuit board to do "three defenses" processing.

The environment of the industrial site is worse than the normal environment, at least in vibration. Its humidity and temperature are also worse than that of ordinary environments. Ordinary switches are not designed to withstand the various situations that occur in industrial environments. Ordinary switches cannot work for long periods of time in such harsh environments. They are often prone to failures, which increases maintenance costs. It is generally not recommended to use commercial switches in industrial environments. In order to enable the switches to be used in such harsh environments, switches that can adapt to these environments are produced. Industrial-grade switch reliability: if there is power failure, the port is interrupted, the relay can output alarm, redundant dual DC power can be input, active circuit protection, over voltage and under voltage automatic circuit breaker protection can be started.
