摘要
对自行研究设计的编程控制器硬件(使用MSP430系列微处理器作为核心控制芯片)进行软件平台的开发,实现后主要的应用平台是针对现场测控RTU、PLC等。该软件能够实现梯形图符号的编辑、语法检测、逻辑错误检查等功能。在软件中实现图形到逻辑代码转换时,提出了逆向递归算法、梯形图优化方法;程序调试下载是利用JTAG接口技术来实现。
In view of the independently designed programmable controller and application requirement, the aim is to do research on design of graphical programming software integration conditions. Based on the analysis of traditional programmable controller environment, it uses the international standard and the existing technology, developes the optimized graphical language integrated development environment. This platform is of great versatility, conforms to the present graphical language programming standard, aims at measure and control of RTU and PLC online. It presents the ladder diagram, develops the joint used to load down the program with JTAG
