一种高速卷烟机EtherCAT从站设计

Design of EtherCAT Slave Station for High Speed Cigarette Machine

文章根据目前在高速、超高速卷烟机组上大量使用的嵌入式PC现状,使用从站芯片和DSP,设计了一个EtherCAT从站,实现了模拟量数据采集和标准的EtherCAT协议通讯。重点介绍了系统的硬件设计和软件设计,其中LAN9252完成从站的EtherCAT协议通讯,而DSP芯片负责从站初始化、模拟量采集、数据收发、状态管理等。

According to the presem situation of embedded PC widely used in high speed cigarette units, the author utilizes the slave station chips and DSP to design an EtherCAT slave station, which implements the analog data acquisition and standard protocol communication. The hardware design and software design of the system are introduced in this paper. The LAN9252 chip is used to implement the EtherCAT protocol communication of slave station. The DSP chips are responsible lbr the initialization of the station, the analog signal acquisition, the data receiving and dispatching, and the state management.
