摘　　要：PLC编程语言主要采用梯形图、指令表和状态转移图,目前PLC普遍采用梯形图编程语言,以其直观、形象、简单等特点为广大用户所熟悉和接受。但是,随着PLC功能的不断增强,梯形图一统天下的局面将被打破,多种语言并存互补不足将是今后PLC编程语言的发展趋势。对于PLC初学者的学习应该多种编程方法相结合,分别采用梯形图和状态转移图对电动机进行正反转控制,通过对比分析两种不同编程方法的优缺点。PLC programming language mainly uses ladder diagram,instruction list and state transition diagram.At present,PLC generally adopts ladder diagram programming language.It is familiar and accepted by users for its characteristics of intuition,image and simplicity.However,with the continuous enhancement of PLC function,the situation that the ladder diagram unified the whole situation will be broken,and the coexistence and complementarity of many languages will be the development trend of PLC programming language in the future.PLC for beginners learning should be combined with a variety of programming methods,this paper adopts ladder diagram and state diagram for positive control of the motor,the advantages and disadvantages of two different programming methods through comparative analysis.
