對于物聯(lián)網(wǎng)產(chǎn)業(yè)MCU和EtherCAT齒輪

　　數(shù)以百萬計的世界各地的工廠和加工廠的控制和處理節(jié)點、工業(yè)控制自動化是物聯(lián)網(wǎng)（IoT）的下一個前沿和32位的MCUs將發(fā)揮重要作用。

　　以太網(wǎng)是連接制造節(jié)點創(chuàng)建一個工業(yè)物聯(lián)網(wǎng)的顯而易見的選擇（IIoT）。通過采用以太網(wǎng)技術(shù)，工廠的地板可以無縫集成到企業(yè)，這將允許更快的制造響應(yīng)不斷變化的業(yè)務(wù)條件，集中維護和診斷，以及卓越的工廠自動化一般。

　　However， standard Ethernet falls short of the critical factory-automation requirements for two basic reasons：

　　Its MAC layer does not support real-time， low-latency data transfers. Standard Ethernet works for IT because it lets individual nodes take control of the network and transmit relatively large packets of data. Control networks common in industry need deterministic transfer of relatively small amounts of control or status data.

　　Its star， switch-based topology is very dissimilar from networks found in manufacturing and processing plants.

　　To solve these problems， over 2，600 companies have endorsed EtherCAT （Ethernet for Control Automation Technology）， which adds real-time and other capabilities to classic Ethernet and enforces configurations that make it a very efficient automation network technology while fully conforming to Ethernet specifications. The EtherCAT Technology Group maintains the standard， which is part of the International Electrotechnical Commission （IEC） body of standards.
