一种EtherCAT与CAN通信的网关及其通信方法
摘要：
本发明公开了一种EtherCAT网关及其通信方法，所述的网关包括EtherCAT协议控制器、EtherCAT收发器、ARM中央控制器、CAN总线控制器、CAN总线收发器。ARM中央控制器分别与EtherCAT协议控制器和CAN总线控制器双向连接；所述的EtherCAT协议控制器通过EtherCAT协议收发器与EtherCAT工业以太网双向连接；所述的CAN总线控制器通过CAN总线收发器与CAN总线双向连接。本发明通过ARM中央控制器实现了EtherCAT协议控制器与CAN总线控制器的数据交换，解决了EtherCAT实时工业以太网与CAN总线通信的互联问题。
摘要（英）：

The invention discloses a gateway of communication between Ethernet for control and automation technology (EtherCAT) and CAN, and a communication method thereof. The gateway comprises an EtherCAT protocol controller, an EtherCAT PHY, an ARM central controller, a CAN bus controller and a CAN bus transceiver. The ARM central controller is respectively bi-directionally connected with the EtherCAT protocol controller and the CAN bus controller. The EtherCAT protocol controller is bi-directionally connected with EtherCAT industrial Ethernet through the EtherCAT PHY. The CAN bus controller is bi-directionally connected with CAN bus through the CAN bus transceiver. In the invention, data exchange between the EtherCAT protocol controller and the CAN bus controller can be realized through the ARM central controller; an interconnection problem of the communication between the EtherCAT real-time industrial Ethernet and the CAN bus.
