摘　　要：本文指出了在PLC程序设计中习惯采用的由类似于继电器线圈及其接点等符号组成的梯形图程序的缺点,在程序设计中提出了用编码实现状态识别的控制算法。设计的程序结构性强,易于阅读、修改及调试,当生产条件发生变化后,很容易实现功能的扩充,体现了PLC较强的适应性。The weaknesses of habitually adopted ladder diagram program composed of symbols similar to relay coils and their contacts in the Programmable Logic Controller ( PLC) program design are pointed out. The control algorithm which uses codes to identify the state is raised. The designed program has fairly good structure. It is easy to read, modify, debug and enlarge its function when the production condition changes, which embodies the PLC' s well adaptability.
