    Industrial Ethernet

    KHES500 series of industrial switches is a new generation of two layer industrial switches with high performance, multi function, high reliability and security.
    In the field of industrial automation, the connection of each industrial equipment plays a very important role in the whole industrial system. Unlike the general office application, when the Ethernet network equipment the connection failed, only that PC can not transfer information in a few minutes; but in industrial applications, online outage may cause significant economic losses. Therefore, in order to ensure the smooth operation of the whole industrial system, the following points should be paid attention to when choosing industrial Ethernet equipment to meet the needs of industrial applications:
    1 equipment must have high reliability in industrial applications.
    2 the need for fast recovery and security, to ensure the continuous operation of the device.
    3 accident alarm function, that the state of industrial equipment, to prevent damage to the system
    4 efficient management allows you to easily grasp the industrial Ethernet
    First, the equipment must have high reliability in industrial applications
    In fact, it has become a new developing trend to apply Ethernet products to the high standard industrial environment. In order to achieve the reliability of industrial applications, the design of industrial switches in the era of the sea and the sea is strictly in compliance with industrial standards:
    - product selection of industrial grade components in the design
    L product can adapt to the harsh environment of industrial site
    L power redundancy, wide voltage design
    No fan of the product - Thermal Design
    Design - alloy shell of high strength products
    - product protection structure of IP40 IP grade and above
    - redundant network link failure recovery time is less than 30ms
    L abundant network function, the software function module of traditional inheritance system
    Two, the need for rapid recovery of the online interrupt function and security, to ensure the continuous operation of the device
    The characteristics listed above, can only meet the basic needs of industrial applications; when considering the industrial data transmission problems, reliability refers not only to have solid shell and good temperature resistance, also includes on-line recovery function after interruption. In the office environment, 3 minutes of online failure may only cause some minor inconvenience; but in the industrial environment, the same 3 minutes of online failure, will likely cause huge economic losses. Therefore, a self recovery network will be available to provide continuous online:
    L self recovery network system (KHring < 20ms), in order to avoid any interruption online.
    L advanced network management software (SNMPv1/v2C), which can realize the network topology, when a link failure, can quickly solve the problem.
    Three, dynamic state alarm function, to know the state of industrial equipment, to prevent damage to the system
    Industrial Ethernet networking equipment has the responsibility to provide real-time warning messages for system maintenance. Even when the control engineer leaves the control room, they also need to be informed of the status of the device in time. In addition, the warning message must be transmitted according to the event's trigger. Based on these requirements, the Hong Hai era industrial switches have the following requirements:
    - the accident immediately send alerts (e.g. via SMS or E-mail).
    L provide electric remote hardware fail alarm equipment (such as: digital output, relay output) to remind the engineering staff.
    L advanced network management software (SNMPv1/v2C), which can generate a log, call for engineers.
    Four, efficient management allows you to easily grasp the industrial Ethernet
    L to confirm the integrity of the network through the transfer section of the "Ping" command
    From the remote site network analysis facility
    - automatic distribution device is connected to the IP address
    L set mirror port, to provide online monitoring data better
    - Simple Network Management Protocol (SNMPv1/v2C) easily support network analysis
    In short, Kanghai era of industrial Ethernet equipment requires not only durable design, so that it can operate in harsh industrial environments, but also have many useful management and monitoring functions, such as: self recovery system, isolation of unauthorized persons from entering the system, automatic alarm trigger event E-mail. Additional features include: the transfer of the "Ping" command to view the network section of the problem, can be connected to set the IP address of the device, the implementation of port mirroring to monitor the operation of the real port, etc..
