INFI-90DCS控制系统故障诊断软件的设计与应用

Design and Application of INFI-90 DCS Control System Fault Diagnostic Software

采用了ABBINFI-90DCS控制系统提供的semAPI协议及IC103模件通讯接口组件，独立开发出通用的、开放的分布式DCS系统诊断程序，以阐述DCS接口软件技术在工厂的实际应用。

A common-used, opened and distributed DCS system fault diagnostic software was developed base on the semAPl protocol and ICI03 module communication interface components supplied by ABB INFI-90 DCS control system and used in ABB INFI-90 DCS system,expounded to illustrate the actual usage of the DCS communication interface in the power plant. Development of the distributed DCS interface software run on WindowsNT/2000 operating system,the server/client system structure.The server was connected in the local area network or independent network,take the responsibility of data collection,saving and transmission,and the client computer run fault diagnostic program read the real time process value from the server through the network,and also the client computer completed the user diagnostic software defined diagnosis and alarm function.
