Abstract:
1. An Ethernet-based data transmission method for use in a control system, wherein the control system comprises a plurality of nodes and a switch, the plurality of nodes comprise at least one servo driver, and, the data transmission method-comprises: buffering, by a first node in the plurality of nodes, data to be sent; and if a current communication macro cycle includes a time period for the first node to send data, sending, by the first node, the buffered data in the time period for the first node to send data within the current communication macro cycle, and if the current communication macro cycle does not include the time period for the first node to send data, not sending, by the first node, the buffered data within the current communication macro cycle, wherein other nodes do not send data in the time period for the first node to send data within the current communication macro cycle, each communication macro cycle has a same duration, and each communication macro cycle consists of a plurality of fixed duration time periods.
