摘要
ctiveX控件是Windows下进行应用程序开发的崭新技术 ,使用MSComm控件可简化Windows环境下串行通信程序的设计 .可编程控制器在分布式控制中作为前端下位机得到越来越广泛的应用 ,实现可编程控制器通信是进行Windows程序设计的关键技术之一 .阐述了一种用C2 0 0H系列可编程控制器构成的分布式控制系统 。
It's a brand-new technology for ActiveX to develo p application program under Windows.The designing of serial communication program can be simplified by making use of MSComm. PLC in distributed control system as front end computer is used more and more extensively. To achieve PLC communication is one of the key techno logy in Windows programming. This paper also presents a distributed control syst em with C200H PLC. Especially, it discusses the communication protocol and desig n method of communication program.
