Design and Application of Servo Performance Analysis Tool Based on EtherCAT Protocol
With the continuous improvement of real-time and precision requirements in the field of industrial control,EtherCAT bus technology has been widely applied in servo control systems,and the performance of servo systems is of great significance for achieving precise motion control.Therefore,a servo performance analysis method based on EtherCAT message data is proposed.Firstly,use Wireshark network packet software to intercept EtherCAT communication data and export it in pcapng file format.Then,according to the message specifications of the EtherCAT protocol,use VC++ to parse it to obtain process data objects.Finally,use these data objects to analyze the positioning error,position tracking error,position stability time,and positioning time of the server system.The design of EtherCAT message parsing tool provides a new approach and tool support for servo performance analysis.
