摘要
为了实现PLC指令表语句向梯形图自动转换,该文首先提出了指令表语句向梯形图转化需要的限制条件,同时,根据指令表语句本身的意义,以及梯形图绘图的结构,提出了基于块生长的观点的算法,实现这一自动转换。本算法已经成功应用于上海研翔自动化有限公司的PLC编程软件当中。
A transformation algorithm from PLC instruction list to ladder diagram based on blocks was proposed.The conditions with which the instruction list could be transformed to Ladder Diagram were listed firstly.And the algorithm was saw to the mean of instruction and the structure of the ladder diagram.The algorithm was succeed used in the software of Shanghai Yanxiang Ltd.
