德国倍福beckhoff 总线耦合器 BK模块
EtherCAT（Ethernet Control Automation Technology，用于控制和自动化技术的以太网）是用于工业自动化的以太网解决方案，其特点是性能X越、操作简便。Ether¬CAT 可以用简单的线形拓扑结构来代替以太网星型结构，也可以采用“传统”方式，即采用交换机对 EtherCAT 进行布线，以便集成其它以太网设备。主站无需X插卡，只需使用一个非常简单的接口即可实现与任何一台现有以太网控制器的连接。因此 EtherCAT 也非常适用于小型和中型控制应用场合，从而也为分布式 I/O 开辟了新的应用X域。
对于 EtherCAT，符合 IP20 防护等X的分布式 I/O 系统亦可以 EtherCAT 端子模块的形式提供。与总线端子模块不同的是，现场总线的协议数据是在总线耦合器内部实现转换，然后传递给X立于现场总线的内部端子总线（指K-Bus），而EtherCAT 协议则在完全保持不变的状态下直达各个 EtherCAT 端子模块。ELxxxx EtherCAT 端子模块可通过相关的 EKxxxx 型号的 EtherCAT 耦合器接入（请参阅 EtherCAT 部分）。
