摘要
介绍了软PLC系统的结构,并针对PLC编程标准,给出了一种软PLC语言编辑系统的实现方法。将PLC梯形图逻辑表示为XML数据,配以相应的语言转换程序,可将XML结构数据转换成PLC设备的编程语言,具有开放标准的XML数据文件使软PLC具有极大的灵活性和扩展性。
The article introduces the architecture of SoftPLC and presents a method for realizing the language editing system of SoftPLC according to programming standard of PLC. The methods turning ladder diagram logical into XML data are discussed collocating language transform program corresponding. It may automatic ally changeally XML structure data into the program language of PLC. It is of huge flexibility and expansibility of system that XML data files have open criterion.
