基于Codesys平台的非标自动化设备轴控框架程序设计

Design of Axis Control Framework Program for Non-Standard Automated Equipment Based on the Codesys Platform

摘要: 本文提出了一种基于Codesys平台与EtherCAT总线的非标自动化设备轴控框架设计方案。针对非标设备开发中复用率低、兼容性差和维护困难的痛点，作者设计了包含“硬件层–功能块层–交互层”的三层架构。硬件层利用EtherCAT实现高速同步；功能块层使用ST语言封装了标准化的轴控功能(如使能、回原点、定位)；交互层设计了通用的触摸屏界面。文章通过在电子元件装配设备上的实际应用和对比测试，验证了该框架在缩短开发周期(40%)和降低维护成本(35%)方面的有效性，并测试了跨品牌硬件的兼容性。

Abstract: This paper proposes a design scheme of the axis control framework for non-standard automation equipment based on the Codesys platform and EtherCAT bus. Aiming at the pain points of low reusability, poor compatibility and difficult maintenance in the development of non-standard equipment, the authors have designed a three-layer architecture consisting of the hardware layer, function block layer and interaction layer. The hardware layer adopts EtherCAT to achieve high-speed synchronization; the function block layer uses Structured Text (ST) to encapsulate standardized axis control functions (such as enabling, homing and positioning); the interaction layer is equipped with a universal touchscreen interface. Through practical application and comparative tests on an electronic component assembly equipment, the paper verifies the effectiveness of the framework in shortening the development cycle by 40% and reducing the maintenance cost by 35%, and also tests its compatibility with cross-brand hardware.
