这是在2003年4月德国汉诺威博览会上第一次展出并很快成为自动化工程师热衷讨论的话题——来自Beckhoff公司的新型、实时以太网网络EtherCAT(Ethernet for control automation technolo-gy)EtherCAT之所以引人注意在于其优越的性能、特别方便的接线和向其它协议的开放性。EtherCAT的特点:1 000数字量I/O的更新时间为30μs;可选用双绞线电缆或光缆以及由于Eth-ernet和Internet技术的优化垂直集成。Ether CAT使你能根据实际情况选用传统的价格昂贵的星形拓扑或是简单的低成本线型结构——不需要高价
This was first exhibited at the Hanover Fair in Germany in April 2003 and soon became a hot topic for automation engineers - EtherCAT, a new, real-time Ethernet network from Beckhoff So the attraction is its superior performance, especially easy wiring and openness to other protocols. EtherCAT features: 1 000 digital I / O update time of 30μs; optional twisted-pair cable or fiber optic cable and due to the vertical integration of Eth-ernet and Internet technology. Ether CAT allows you to choose from the traditional expensive star topology or a simple, low-cost linear structure - without the need for expensive
