摘要
面向对象的程序设计方法已经成功运用于计算机软件的开发、代码重用的有效实现大大简化了软件的开发和维护 在STEP 7软件开发中 ,通过借鉴面向对象的设计方法 ,使PLC的程序设计更加简单 ,设计的系统更加可靠 ,后续开发更加方便 。
Object oriented methodology has been successfully used to develop many kinds of software and make it sample to develop and maintain a software especially a big project.This article discuss in STEP 7 by using the Object oriented methodology,a PLC program can be safely designed,easily developed,and conveniently maintained,which could make the software design method of the PLC access the industrial standard.
