The design and implementation of configuration software for industrial controlis a complex engineering. This paper describes the whole frame and implementationof supervisory and control configuration software, and also provides part source codebased on VC++6.0. A prototype of such kind of software is realized. The whole system can be divided into following components: graphic interface,real-time database system, running system, communication system. The paper mainlydiscusses the design of graphic interface and real-time database system. Several characteristics are put forward in my own software on the base ofreference to some famous domestics and overseas products. Firstly, taking advantageof sharing memory file to exchange system data, which is simple and reliable, alsoeasy to implement, Secondly, Object-Oriented model for real-time database isdesigned, the mapping between relation database and Real-time database is perfectlyrealized, some functions are replaced by relation database. Thirdly we have designedgraphic interface configuration module making use of Object-Oriented technology,meanwhile basic graphic unit is defined, the method how to encapsulate graphicsedition during drawing course is discussed, a set of tool classes are designed toencapsulate various kinds of drawing course. Also combining with computer graphics,we discussed how to imitate supervised objects with dynamical displayingcharacteristics of graphics. Finally, The expansion of configuration software isstrengthened as result of integration of VBA and itself. The scheme offered in the paper is proved to be correct and practicable byexperiment, and it has strong operability.
