【Abstract】 The principle and technique of the real-time dynamic data exchange for industrial control system is introduced; and an example of a plant computer net monitor system of dynamic data is given. Combining with realization, how to use DDE and ASP to complete the net monitor system is explained; and the data exchanging between Web and iFIX is effectively implemented. The system that designed by this mode has been put into operation. It is proved that the systemis effective and reliable in application and can satisfy the request that the net monitoring system need, make the data application processing easier and more direct.更多还原
