1. Environmental requirements: The reason why the industrial computer is different from the ordinary civil computer is that it can be used in harsh environments, such as ultra-high or ultra-low temperature, high dust, high vibration and other occasions, so when choosing an industrial computer, it is necessary to carefully check whether its parameters can meet the requirements of your application environment.

Commonly used types of industrial computers are: Standard 4U IPC Fanless embedded IPC Customize the BOX host Industrial Servers Industrial Tablet PCs Multi-network port network security equipment ...

On November 6, the 2022 Industrial Upgrading and Global Supply Chain Summit Forum with the theme of "Joint Innovation and Breakthrough" and the signing ceremony between Eternal Asia and global brands were held in Shanghai. The forum was guided by the Shenzhen Municipal Bureau of Commerce and the People's Government of Bao'an District, Shenzhen.

1.4U IPC chassis characteristics are generally used in dust, smoke, high and low temperature, humidity, vibration, corrosion and other harsh environments, in this way, the requirements for 4U IPC chassis are very strict, 4U IPC chassis must be able to withstand so many harsh conditions, in order to protect...

Everyone in the industrial Internet circle knows that the concept of digital twin has been very popular in recent years, and it is a powerful assistant for the digital transformation of factories. However, in the face of its own weak technical strength and complex equipment use scenarios, is there a solution that can be used out of the box, or through simple configuration...

1、Telnet The Telnet protocol is a remote access protocol through which you can log in to the switch for configuration. Assuming that the IP address of the switch is 192.168.0.1, you only need to perform two steps to configure the switch through Telnet: Step 1, click Start, Run, Type ...

1. The position in the OSI model is different. Switches are devices that have evolved from bridges and are at the second layer in the OSI model, which is the data link layer. Routers are the third layer of the OSI model and belong to the network layer devices. 2. Different addressing methods. The switch is based on the MAC address ...

(1) The transmission rate is different The transmission rate of the common optical port can reach more than 100G, and the maximum rate of the commonly used electrical port is only 10G. (2) The transmission distance is different The maximum transmission distance of the optical module inserted into the optical port can be more than 100KM, and the maximum transmission distance of the electrical port connection network cable is 10 km.

Industrial Ethernet switches are specifically designed to meet the needs of flexible industrial applications, providing a cost-effective Industrial Ethernet communication solution. The networking method focuses more on loop design. There is a distinction between single-loop and multi-loop loops, and there are also differences between STP and RSTP foundations.

1. Backplane bandwidth: determines the maximum connection bandwidth between each interface template and the switching engine. Backplane bandwidth is the maximum amount of data that can be handled between a switch's interface processor or interface card and the data bus. The backplane bandwidth indicates the total data exchange capability of the switch, in units ...

Learning function: The Ethernet switch learns the MAC address of the device connected to each port, maps the address with the corresponding port, and stores it in the MAC address table in the switch cache. Forwarding Filtering: When the destination address of a data frame is mapped in the MAC address table, it is ...

1) Select credible technical indicators, such as switching speed, switching capacity (Gbps), backplane bandwidth (Gbps), processing capacity (Mpps), and throughput (Mpps). 2) Design the correct test plan, and prepare enough test ports to accurately evaluate the ...

1. VLANs based on port division 2. Divide VLANs based on MAC addresses 3. Divide VLANs based on network layer protocols 4. Divide VLANs based on IP multicast 5. Divide VLANs by policy 6. Divide VLANs based on user-defined and non-user-authorized VLANs ...

(1) Zero self-healing ring network technology to achieve high reliability and integrity of data transmission Prior to this, the fastest fault self-healing time of the world's industrial switches was 20 milliseconds. However, no matter how short the self-healing time of the ring network fault is, the loss of data packets will inevitably be caused during the switchover period.

1. Climate and environment: The industrial switch can better adapt to the poor climate environment, including temperature, humidity, etc., and can be used normally in the ambient temperature of -40-+85°C, and the lightning protection of the product port is 3600V and above. 2. Working voltage: Industrial Switches ...

On December 2, 2022, Advantech and Shanghai Shunyuan Computer Technology Co., Ltd. (hereinafter referred to as "Shunyuan Technology") held a strategic cooperation signing ceremony in Shanghai. The two parties will give full play to the advantages of independent core technology and resource integration, and develop a strong role in the business segment of domestic chips (Haiguang and Zhaoxin) and information security.

(1) Zero self-healing ring network technology to achieve high reliability and integrity of data transmission Prior to this, the fastest fault self-healing time of the world's industrial switches was 20 milliseconds. However, no matter how short the self-healing time of the ring network fault is, the loss of data packets will inevitably be caused during the switchover period.

1. Cybersecurity In advanced industrial applications, cybersecurity has become an issue to be solved. Many domestic manufacturers (such as Dongtu, Mosa, Mabwell, etc.) have produced a series of Web managed industrial switches to provide a variety of functions for network security problems in the LAN.

(1) Large cache technology The data center switch has changed the outbound port cache mode of the traditional switch, and adopts a distributed cache architecture, which is much larger than that of ordinary switches, and the cache capacity can reach more than 1G, while the general switch can only reach 2-4M. Full line rate for each port in 10 megabits ...

Troubleshooting method: (1) Exclusion method: When we are confronted with the fault phenomenon and analyze the problem, we have inadvertently learned to use the elimination method to determine the direction of the failure.
