Abstract

The embodiment of the invention provides an Ethercat master-slave synchronization method and device and a master-slave station system. The method comprises the steps that synchronization configuration stages between Ethercat slave stations are configured in an Ethercat master station, and a fixed configuration period serves as the configuration period of the configuration stages; synchronization configuration stages of the Ethercat master station and the Ethercat slave stations are configured in the Ethercat master station, and synchronization of the Ethercat master station configuration period and the Ethercat slave station synchronization signal period is dynamically determined in the configuration stages. The effect of the configured Ethercat master station is better.

Description

technical field [0001] The invention relates to the technical field of automation control, and more specifically, relates to an Ethercat master-slave synchronization method and device and a master-slave station system. Background technique [0002] Ethercat (Ethernet for Control Automation Technology, Ethernet control automation technology) is an open real-time Ethernet communication protocol. It is an Ethernet-based field bus system. constitute. The Ethercat bus has the characteristics of high speed and high data efficiency, and supports a variety of device connection topologies; therefore, applying Ethercat technology to motion control systems and other control systems that require high real-time data processing will make the response of the control system The speed and control precision have been greatly improved. [0003] The Ethercat master station is a device in the Ethercat master-slave station system; when constructing the Ethercat master station, it is necessary t...
