【摘要】 介绍了用VC++和VB联合开发针对I/O测控卡的软构件(Active X)的制作方法,从而实现了工控机对I/O模块进行读写、定时采样和异常事件实时触发等功能,为对新I/O模块接入原系统,提供了一种开发I/O驱动软件的方法.更多还原

【Abstract】 The paper introduced the fabrication method of the soft component (ActiveX) for I/O measurement and control modules by using VC + + and VB in combination. Thus the functions of read-rate access, timing sampling and realtime trigger on abnormal events for I/O modules are implemented by IPC. A method of developing I/O driving software is provided to connect the new I/O modules into the existing svstem.更多还原
