梯形图以指令的形式储存在PLC的用户程序存储器中,图l-6中的梯形图与下面的5条指令相对应,“;”之后是该指令的注释。
LD X0 :接在左侧母线上的X0的常开触点
OR Y0 ;与X0的常开触点并联的Y0的常开触点
ANI X1 ;与并联电路串联的X1的常闭触点
ANI X2 ;串联的X2的常闭触点
OUT Y0 ;Y0的线圈
图1-6中的梯形图完成的逻辑运算为
Y0=(X0+Y0)·X1·X2
在输入处理阶段,CPU将SBl,SB2和FR的常开触点的状态读入相应的输入映像寄存器,外部触点接通时存入寄存器的是二进制数l,反之存入0。
执行第l条指令时,从X0对应的输入映像寄存器中取出二进制数并保存起来。执行第2条指令时,取出Y0对应的输出映像寄存器中的二进制数,与X0对应的二进制数相“或”(电路的并联对应“或”运算)。
执行第3条或第4条指令时,分别取出xl或X2对应的输入映像寄存器中的二进制数,因为是常闭触点,取反后与前面的运算结果相“与”(电路的串联对应“与”运算),然后存入运算结果寄存器。
