I. What is an industrial switch?
Industrial switches, also known as industrial Ethernet switches, are Ethernet switching devices used in the industrial control field. Due to the network standards they adopt, they are highly open, widely used, and inexpensive. They also use the transparent and unified TCP/IP protocol, making Ethernet the main communication standard in the industrial control field.
Industrial switches feature carrier-grade performance characteristics and can withstand harsh operating environments. A comprehensive product range and flexible port configurations cater to the needs of various industrial sectors. The products employ a wide-temperature design, offer a protection rating of at least IP30, and support standard and proprietary ring network redundancy protocols.
While there is no fundamental difference between industrial Ethernet and commercial networks in terms of data link layer, network layer, and protocol layer, industrial Ethernet addresses technical issues such as real-time communication, network security, intrinsic safety, and explosion-proof technology to meet the real-time requirements of industrial control. It also adopts measures suitable for industrial environments, such as waterproofing and vibration resistance. At its core, however, there is no fundamental difference between industrial Ethernet and commercial Ethernet, just like the difference between a PC and an industrial control computer.
Industrial Ethernet switches are specifically designed to meet the flexible and diverse needs of industrial applications, providing a cost-effective industrial Ethernet communication solution. Their networking methods focus primarily on loop design. Loops can be single-ring or multi-ring, and there are also proprietary loop protocols designed by various manufacturers based on STP and RSTP, such as RingOn, RingOpen, FRP rings, and turbo rings.
II. Differences between Industrial Control Switches and Industrial Switches
Through the above introduction, you should now have a clear understanding of the concept of industrial switches. In this section, we will mainly discuss the differences between industrial control switches and industrial switches.
Ethernet switches are generally classified into: commercial (Ethernet) switches, industrial (Ethernet) switches, and home (Ethernet) switches.
Commercial switches are generally used in enterprise office networks and other similar applications. They are typically rack-mounted and installed in enterprise server rooms. They usually require high reliability, the ability to operate continuously 24 hours a day, and feature large bandwidth and a large number of interfaces.
Industrial switches are generally used in industrial production environments. They typically come in various appearances and installation methods. Depending on the application, requirements may include waterproofing, dustproofing, shock resistance, and electromagnetic interference resistance, as well as high reliability, requiring continuous 24/7 operation. Some automatic control applications require low forwarding latency, while others require redundant power supplies, such as DC 24V power supplies.
Some automatic control applications require low forwarding latency, while others require redundant power supplies, such as DC 24V power. You've probably heard of what's called an industrial switch—an industrial control switch. So, what's the difference between an industrial switch and an industrial control switch?
"Industrial control switch" isn't actually a standard name; it's more of a colloquial term. Switches used in the industrial control sector are often called industrial switches.
In standard terms, there are three things: industrial PCs, program-controlled exchanges, and telephone exchanges. An industrial PC is an industrial-grade PC, or a variant of a PC, primarily used to run specific programs. A program-controlled exchange is simply a telephone exchange; companies need this if they want to install a main switchboard and extensions.
A switch is obviously for PCs. Ethernet is a standard network protocol, and all networks we use now are based on Ethernet. All switches and Ethernet switches are essentially the same thing; we don't usually call them that. As for industrial switches, they are distinguished from managed switches used in homes. Actually, there isn't such a clear definition for these products. Currently, managed switches are only around 200-300 RMB, which is perfectly adequate for home use.
Another point is working hours. Industrial appliances generally support 24/7 operation, but nowadays home appliances are often powered on continuously, so there's no need to distinguish them so clearly.
