摘要
针对EtherCAT现场总线中临时从站关机插拔带来的低效问题,基于TwinCAT软件提出一种支持实时检测和反馈的可靠解决方案。在分析EtherCAT报文的基础上,采用设置同步单元和分配工作状态字的方法,以不影响其他设备EtherCAT通讯为前提,最大化地降低关机插拔对生产过程的影响,缩减EtherCAT的整体诊断时间,提高生产效率,在现场生产中具有较好的推广应用价值。
Interim stations need to turn them off and plug on EtherCAT fieldbus, leading to poor efficlency. A reliable solution based on TwinCAT software that supports real - time detection and feedback is proposed. The frames of the EtherCAT are analyzed. The impact of shutdown and plug on the process of production is reduced by setting a synchronization unit and assigning working counter without affecting the communication of other EtherCAT equipment, thus faster EtherCAT diagnosis and higher efficiency of production.
