Abstract
In order to achieve the coordination of the system,the equipments must be used fully,so the system integration attracted more attention.Object Link and Embed technology were applied to industry process control by the technology of OPC,which created conditions for integration of industry control system.OPC was mainly developed based on COM/DCOM technology.Firstly,a composite industry control system that was based on OPC was set up by occupational OPC criterion and COM.The landscape and portrait integration were realized,and the question of veracity in net transmission was resolved.The real-time,openness and expansibility of the system were improved by adopting Switched Ethernet.
