上位监控软件在线扩展功能的开发

Development of on-line function expending to monitor program

本文介绍了一种通过基于动态链接库的插件技术实现监控程序的在线功能扩展的方法。通过西门子的PRODAVE软件和VC++实现了对S7-300PLC的监控,从而检验了方案的可行性。

This paper introduces a method to extend functions of a monitor program on-line through plug-ins basing on dynamic link libraries. A program created by PRODAVE of siemens and VC＋＋ has monitored a S7-300PLC successfully, which proves this scheme to be feasible.
