摘　　要：针对软PLC开发系统专业要求高、无法在线修改程序、不利于终端用户使用等问题,开发独立于软PLC运行系统的上位机控制平台,以图形化方式实现程序编辑,以XML文档作为控制平台与软PLC运行系统间的中间代码,通过在软PLC运行系统内开发解释层,实现XML文档到底层控制程序的转换,从而实现用户的控制逻辑。Because the soft PLC development system needs high specialized requirement,it is hard to modify online control program.It is not suitable to the end users.To solve the problem,this paper develops a control platform which is used on PC device to help users editing program.This platform provides a graphic programming interface and XML file is chosen as inter code file between PC device and soft PLC.The developed interpretive layer in soft PLC is used to transform the XML document to the underlying control program,thus finally realizing the logic control of the users.

关 键 词：软PLC XML语言 控制平台 中间解释层
