Features and utility of industrial switches
Industrial switch, also known as industrial production Ethernet switch, that is, Ethernet switch equipment used in industrial control systems, because the use of the Internet specification of its open, good use of common below I interpret it.
I. Characteristics of industrial switches:
1, industrial switches can work normally in the temperature range of -40℃-- 75℃, and commercial commodities only work in the range of 0℃-- 50℃, can not meet the requirements of the work site.
2, the switch can work in the harsh induction coil ring (circular conducting magnetic field) environment, and in the data information port lightning protection, rapid pulse group, tip discharge (is a kind of stationary mode of positive electricity) is a higher level of waterproof, and commercial use of the commodity this point is not available
3, flexible assembly mode industrial switch can be used DIN slide rail, wall, sound card rack and other installation methods, convenient and fast in a variety of system software applications in the geographical environment, and commercial commodities see desktop, rack installation
II.Industrial switch application:
1. In different application scenarios, the frame rate and shake that the system software can bear vary greatly. Data frames in automated Internet technology have a lag time each time they are shared from one device to another. Therefore, when selecting an industrial switch, the port delay of the network switch in the whole process of data frame sharing must be fully considered at the very beginning. In a standard factory automation automatic control system, the response speed that the system software can bear is not more than 10ms. In order to better control the cumulative delay of data frames from the top to the end of the system software, When selecting a network switch, note that the network switch port delay is more than 10 microseconds.
2. Industrial Ethernet switches and other industrial Ethernet components should be able to use the standard TCP/IP protocol for communication. In any case, all incompatibilities should not exist between industrial Ethernet switches and commercial service gigabit Ethernet devices. In line with different industrial production computer interface solutions, industrial Ethernet equipment should have the corresponding professional capabilities rather than being compatible.
