ETHERCAT controller

The invention discloses EtherCAT (Ethernet Control Automation Technology) equipment. The EtherCAT equipment comprises a communication circuit and a wake-up circuit, the wake-up circuit is configured to determine a condition for sending data to the EtherCAT master node. Based on this condition, the wake-up circuit is configured to generate a wake-up packet. The communication circuitry may be configured to receive an EtherCAT frame originating from an EtherCAT master node. The communication circuitry may be configured to populate the EtherCAT frame with data to be sent to the EtherCAT master node. The communication circuitry may be configured to transmit the EtherCAT frame to an EtherCAT master device. 本发明公开了一种EtherCAT设备，其包括通信电路和唤醒电路。唤醒电路被配置为确定将数据发送到EtherCAT主节点的条件。基于这种条件，唤醒电路被配置为生成唤醒包。通信电路可以被配置为接收源自EtherCAT主节点的EtherCAT帧。通信电路可以被配置为利用待发送到EtherCAT主节点的数据填充EtherCAT帧。通信电路可以被配置为将EtherCAT帧发送到EtherCAT主设备。
