*BECKHOFFE THERCAT?？镋L3356
数据传输过程中的位错误可以通过评估每个设备上的 CRC 校验码进行检测。除断点检测和定位外，通过 EtherCAT 系统协议，传输物理层和拓扑结构使得高品质监控每个独立的传输段成为可能。通过自动分析相关错误计数器，可以精确定位关键网段?？杉觳獠⒍ㄎ?EMC 干扰、有缺陷的连接器或损坏的电缆等不断变化的错误来源，即使它们尚未对网络的自愈能力产生过度影响。
开放性
EtherCAT 技术不仅与以太网*兼容，而且还有特别的设计开放性特点： 该协议可与其它基于以太网的服务和协议并存于同一物理介质中 － 通常只会对整个网络性能有很小程度的影响。任何以太网设备均可通过交换机端子?？榱又烈桓?EtherCAT 总线网段内部，不会影响周期时间。带现场总线接口的设备可通过 EtherCAT 现场总线主站端子?？榧傻酵缰?。UDP 协议变体允许设备整合于任何插槽接口中。EtherCAT 是一个*开放式协议， 它已被认定为一个正式 IEC 规范（IEC/PAS62407）。
