动态数据交换方式实现应用程序与SE300数控系统PLC的数据交换

Data Exchanging Between SE300 and Application by DDE Technology

介绍了动态数据交换(DDE)技术的基本原理,实现了用户应用程序与SE300数控系统PLC的通讯,并在大型数控落地镗铣床和立车中进行了应用,实现了自动对刀偏置以及在线修改机床参数功能。

This article introduces the principle about DDE,the realization of the application program which was made by the user to communicate with the PLC of SE300 CNC.And it's application on the floor type boring and milling machine and vertical turning machine to realize tool-setting offset and modify the machine parameter online.
