Applying object-oriented method to CSIE system

摘要

CSIE (Distributed Control System Configuration Software integrated Environment) system is a platform for developing control schemes in distributed control system (DCS). With CSIE system, Engineers of DCS can configure the control schemes in kindsof configuration languages and define reusable scheme components in any scheme of the same project. CSIE system implements the five configuration languages defined in the IEC 1131-3 standard This paper describes one of these five configuration languages,SFC, and its editing compiling and debugging strategies in detail.The development of CSIE system bases on object-oriented technology fully and successfully This embodies in two aspects: construct object models in the architecture of CSIE system; organize the key algorithms in object-oriented method. Benefiting fromobject-oriented technology, CSIE system has the features of extensibility, adaptability, and reusability.
