| Abstract: | This paper introduces DDE protocol in Windows, and give a method to get data from Modbus Plus network use DDE protocol in Visual C＋＋ 2005. Then these datum were exchanged with Ethernet through Socket protocol. In this paper the core source code was provided. This solution is simple and useful, it is worthwhile for other similar communication system. And it＇s successfully used in a skin pass mill system. |
