摘要：Abstract This paper proposed an innovative method of introducing CAD technology to ePLC. Which allow us design the motion control path and generate the language-specific track file (HPGL instruction file in this paper) using CAD software, and then ePLC parses and executes the track file to complete the motion control. Application of this method will greatly enhance the flexibility of PLC-based motion control system and extend its application range. The feasibility of the design has been verified in the control of Cartesian robot. It can be widely applied to motion control system designed with CAD software.
