功能模块图编程语言的特点:功能模块图程序设计语言的特点是:以功能模块为单位,分析理解控制方案简单容易;功能模块是用图形的形式表达功能,直观性强,对于具有数字逻辑电路基础的设计人员很容易掌握的编程;对规模大、控制逻辑关系复杂的控制系统,由于功能模块图能够清楚表达功能关系,使编程调试时间大大减少。
顺序功能流程图语言(SFC)
顺序功能流程图语言是为了满足顺序逻辑控制而设计的编程语言。编程时将顺序流程动作的过程分成步和转换条件,根据转移条件对控制系统的功能流程顺序进行分配,一步一步的按照顺序动作。每一步代表一个控制功能任务,用方框表示。在方框内含有用于完成相应控制功能任务的梯形图逻辑。这种编程语言使程序结构清晰,易于阅读及维护,大大减轻编程的工作量,缩短编程和调试时间。用于系统的规模校大,程序关系较复杂的场合。图5是一个简单的功能流程编程语言的示意图。
顺序功能流程图编程语言的特点:以功能为主线,按照功能流程的顺序分配,条理清楚,便于对用户程序理解;避免梯形图或其他语言不能顺序动作的缺陷,同时也避免了用梯形图语言对顺序动作编程时,由于机械互锁造成用户程序结构复杂、难以理解的缺陷;用户程序扫描时间也大大缩短。
