摘要
SFC是PLC的一种编程语言,与传统的梯形图编程方法相比,使用SFC流程图语言来设计PLC控制程序,编程者不用考虑各工序步之间的逻辑关系,而只需要对各个工序步骤进行简单的处理设计就能保证机械正确动作,具有结构直观、编程简单、逻辑性不强、稳定性高等特点而得到广泛应用。以四层智能多功能教学电梯控制过程为例,介绍基于SFC的电梯PLC编程方法。
SFC is a programming language of PLC,compared with the traditional method of ladder diagram programming,using SFC language to design the flow chart of PLC control program,the programming of each process step useless consider the logical relationship between,but only for each process step of processing design can be simple to ensure correct operation of mechanical structure,with intuitive programming simple logic is not strong,high stability and widely used.Taking the four layer intelligent multi-function teaching elevator control process as an example,this paper introduces the PLC programming method of elevator based on SFC.
