Industrial Ethernet is an Ethernet technology used in the field of industrial control. It is technically compatible with commercial Ethernet (ie IEEE 802.3 standard), but the actual products and applications are completely different. This mainly represents the design of ordinary commercial Ethernet products, in the selection of materials, product strength, applicability and real-time, interoperability, reliability, anti-interference, intrinsic safety and other aspects can not meet the needs of industrial sites . Therefore, industrial field control applications are different from commercial Ethernet. But what are the advantages of industrial Ethernet?
(1) Wide application
Ethernet is the most widely used computer network technology. Almost all programming languages ​​such as Visual C++, Java, Visual Basic, etc. support Ethernet application development.
(2) High communication rate
At present, 10,100 Mb/s Fast Ethernet has been widely used, and 1Gb/s Ethernet technology has gradually matured, while the traditional fieldbus has a maximum rate of only 12Mb/s (such as Siemens Profibus-DP). Obviously, the speed of Ethernet is much faster than that of traditional fieldbuses, and it can fully meet the ever-increasing bandwidth requirements of industrial control networks.
(3) Strong resource sharing ability
With the development of Internet/Intranet, Ethernet has penetrated into every corner. Users on the network have removed the geographical position of resources, and can browse the data of industrial control site on any computer connected to the Internet. "Control integration", which is unmatched by any other kind of fieldbus.
(4) Great potential for sustainable development
The introduction of Ethernet will provide possibilities for the subsequent development of the control system. Users do not need to research and invest in their own technology upgrades. For this, any existing fieldbus technology is unmatched. At the same time, the development of robotics and intelligent technologies requires communication networks with higher bandwidth and performance, and communication protocols have higher flexibility, which requires Ethernet to be well satisfied.
Plastic Package Diode.Among the electronic components, a device having two electrodes allows only the current to flow in a single direction, and many uses apply its rectification function. The Varicap Diode is used as an electronic adjustable capacitor. Most of the diodes have a current directionality that we often call the "Rectifying" function. The most common function of a diode is to allow only current to pass in a single direction (referred to as forward bias) and block in the reverse direction (referred to as reverse bias). Therefore, the diode can be thought of as an electronic version of the check valve.
