Industrial Ethernet Technology Application Analysis

Huge demand will bring a huge market, and industrial automation component suppliers are increasingly using Ethernet protocols as the standard specification for their products. Many manufacturers also directly use Ethernet technology as a network connection method for new products. Driven by these vendors, this will require machine builders and end customers to shift their mindset from old fieldbus technology to Ethernet technology.

Industrial Ethernet bus is gradually gaining popularity at home and abroad because of its many advantages. Now there are a large number of supporting products in use. Such as Industrial Ethernet HUB, Industrial Ethernet Firewall, Industrial Ethernet, Ethernet to RS232/RS485, Ethernet A/D module, Ethernet D/A module, Ethernet AI module, Ethernet AO module, Ethernet DI module, Ethernet DO module and composite function module.

Ethernet is currently only suitable for information layer applications in industrial control network systems. Ethernet is a Byte-level network, which can only partially replace the fieldbus function, and Ethernet is used for the field I/O level. This is one of the hotspots in the field of industrial control.

The basis and application methods of industrial Ethernet technology are mostly based on the development of commercial Ethernet. Based on the data transmission technology of the world-leading cable network, according to the characteristics of the industrial field, the Ethernet communication protocol is adopted as the basic technology development. Born. The industrial Ethernet market is in great demand. Whether it is to build a modern manufacturing line or to retrofit old equipment, industrial Ethernet will be used in large quantities.

In this regard, the industrial Ethernet market growth rate has also remained high. According to relevant statistics, the number of new industrial network interfaces will be doubled each year. The market capacity of control products such as PLC, DCS and PC_Based driven by the extension of industrial Ethernet technology is even more difficult to calculate.

Compared with ordinary Ethernet, Industrial Ethernet needs to solve many problems such as openness, real-time, synchronization, reliability, anti-interference and security. This is also the difference between industrial automation manufacturers and ordinary IT vendors. Users bring more value to the place.
