Industrial switch is also known as industrial Ethernet switch, that is, Ethernet switch equipment used in the field of industrial control, due to the use of network standards, its openness, wide application and low price, the use of transparent and unified TCP/IP protocol, Ethernet has become the main communication standard in the field of industrial control.
Industrial switches have carrier-grade performance characteristics and can withstand harsh operating environments. The product series is rich and the port configuration is flexible, which can meet the needs of various industrial fields. The product adopts a wide temperature design, the protection level is not less than IP30, and supports standard and private ring network redundancy protocols. There is no essential difference between itself and the commercial network in the data link layer, network layer, protocol layer, etc., but for the real-time needs of industrial control, industrial Ethernet switch solves technical problems such as real-time communication, network security, intrinsic safety and safety explosion-proof technology, and adopts some measures suitable for the industrial environment, such as waterproof, anti-vibration, anti-vibration, etc. Its core is still not fundamentally different from commercial Ethernet, which is the same as the difference between PC and industrial computer.
Industrial Ethernet switches are designed to meet the needs of flexible industrial applications and provide a cost-effective industrial Ethernet communication solution. The networking mode is more focused on loop design. There are single-ring and multi-ring loops, and private loop protocols designed by various manufacturers based on STP and RSTP, such as RingOn, RingOpen, FRP ring, turbo ring, and so on.
The development of hubs gave rise to a device called an unmanaged switch. It can realize the routing function of messages from one port to another port, which is more intelligent than the hub. The unmanaged switch automatically detects the network speed of each network device. In addition, it has a function called the MAC Address Table, which recognizes and remembers devices in the network. In other words, if port 2 receives a message with a specific identifier, then the switch will send all messages with that specific identifier to port 2. This intelligence avoids message conflicts and improves transmission performance, which is a huge improvement over the hub. However, unmanaged switches cannot implement any form of communication detection and redundant configuration functions.
The next generation of Ethernet connected devices is the managed switch. Compared to hubs and unmanaged switches, managed switches have more and more complex features, and the price is much higher – usually 3 to 4 times that of an unmanaged switch.
Managed switches offer more functionality and can usually be fully configured through a network-based interface. It can automatically interact with network devices, and users can manually configure network speed and traffic control for each port. Some older devices may not be able to use automatic interaction, so manual configuration capabilities are essential.
Most managed switches usually also provide some advanced features, such as SNMP(Simple Network Management Protocol) for remote monitoring and configuration, port mapping for diagnostics, VLAN(Virtual local Area Network) for grouping network devices, priority ordering for ensuring priority messages pass through, and so on. With managed switches, redundant networks can be built. Using a ring topology,managed switches can form a ring network.
Each managed switch can automatically determine the optimal transmission path and alternate path, and automatically block the alternate path when the preferred path is interrupted.
