可编程控制器与一般的计算机相类似,在软件方面有系统软件和应用软件之分,只是可编程控制器的系统软件由可编程控制器生产厂家固化在 ROM 中,一般的用户只能在应用软件上进行操作,即通过编程软件来编制用户程序。编程软件是由可编程控制器生产厂家提供的编程语言,至今为止还没有一种能适合各种可编程控制器的通用的编程语言,但是各个可编程控制器发展过程有类似之处,可编程控制器的编程语言即编程工具都大体差不多,一般有如下五种表达方式。
( 一 ) 梯形图( Ladder Diagram )
梯形图是一种以图形符号及图形符号在图中的相互关系表示控制关系的编程语言,它是从继电器控制电路图演变过来的。梯形图将继电器控制电路图进行简化,同时加进了许多功能强大、使用灵活的指令,将微机的特点结合进去,使编程更加容易,而实现的功能却大大超过传统继电器控制电路图,是目前*普通的一种可编程控制器编程语言。
梯形图及符号的画法应按一定规则,各厂家的符号和规则虽不尽相同,但基本上大同小异,如图 1 所示。
图 1 三种不同的梯形图
a) 欧姆龙 b) 松下 c) 三菱
对于梯形图的规则,总结有以下具有共性的几点,如表 1 所示,以便读者加深对可编程控制器变成的认识和学习。
