There is no essential difference between itself and the commercial network in terms of data link layer, network layer, protocol layer, etc., but for the real-time requirements of industrial control, industrial Ethernet solves the real-time communication, network security, intrinsic safety and safety explosion Technical issues such as technology, and adopt some measures that are suitable for industrial environments, such as waterproofing and anti-vibration ... The core is still not fundamentally different from commercial Ethernet, which is the same as the difference between PCs and industrial computers.
Networking method:
Industrial Ethernet switches are specifically designed to meet the needs of flexible and changing industrial applications, and provide a cost-effective industrial Ethernet communication solution. The networking method focuses more on loop design. The ring has the difference between single ring and multi-ring, and there are also private ring protocols designed by various manufacturers based on STP and RSTP, such as RingOn, RingOpen open ring, FRP ring, turbo ring, etc.
Manageable switches can be managed in the following ways: through RS-232 serial port (or parallel port) management, through a web browser management and through network management software management.
1. Management via serial port
The network management switch comes with a serial cable for switch management. First plug one end of the serial cable into the serial port on the back of the switch, and the other end into the serial port of an ordinary computer. Then turn on the switch and the computer. The "Super Terminal" program is provided in both Windows 98 and Windows 2000. Open the "Super Terminal", after setting the connection parameters, you can interact with the switch through the serial cable, as shown in Figure 1. This method does not occupy the bandwidth of the switch, so it is called "Out of Band Management".
In this management mode, the switch provides a menu-driven console interface or command line interface. You can use the "Tab" key or arrow keys to move through the menus and sub-menus, press the Enter key to execute the corresponding command, or use a dedicated switch management command set to manage the switch. The command set of switches of different brands is different, and even the switches of the same brand have different commands. Using menu commands is more convenient in operation.
2. Web management
A managed switch can be managed through the Web (web browser), but an IP address must be assigned to the switch. This IP address has no other purpose except for the management switch. By default, the switch does not have an IP address, and you must specify an IP address through a serial port or other methods to enable this management method.
When using a web browser to manage the switch, the switch is equivalent to a web server, but the webpage is not stored in the hard disk, but in the NVRAM of the switch. The web program in NVRAM can be upgraded through the program. When the administrator enters the IP address of the switch in the browser, the switch transfers the web page to the computer like a server, and it feels like you are visiting a website at this time, as shown in Figure 2. This method occupies the bandwidth of the switch, so it is called "in-band management" (In band).
If you want to manage the switch, just click the corresponding function item on the webpage and change the switch parameters in the text box or drop-down list. Web management can be carried out on the local area network, so remote management can be achieved.
3. Managed by network management software
Manageable switches all follow the SNMP protocol (simple network management protocol). The SNMP protocol is a complete set of network equipment management specifications that comply with international standards. All devices that follow the SNMP protocol can be managed through network management software. You only need to install a set of SNMP network management software on a network management workstation, you can easily manage the switches, routers, servers, etc. on the network through the LAN. The interface of the SNMP network management software is shown in Figure 3, which is also an in-band management method.
The management of NMS switches can be managed by the above three methods. Which method is used? When the switch is initially set up, it often has to be managed out of band; after setting the IP address, you can use the in-band management method. In-band management Because management data is transmitted through a publicly used local area network, remote management can be achieved, but the security is not strong. Out-of-band management is communicated through the serial port, and data is only transferred between the switch and the management machine, so the security is very strong; however, due to the limitation of the length of the serial cable, remote management cannot be achieved. So which way to use depends on your requirements for security and manageability.
Industrial switches are widely used. In terms of industry applications, they are mainly used in: coal mine safety, rail transit, factory automation, water treatment systems, urban security, etc.
