1位逻辑指令

1.1位逻辑指令概述

1.1.1描述

位逻辑指令使用两个数字，1和0。

这两个数字，形成一个数字系统的基础，被称为二进制系统。

1和0两个数字被称为二进制数字或位。

在触点和线圈的世界，1表示激活或通电，0表示没有激活或不通电。

解释1和0位逻辑指令信号状态，并结合他们根据布尔逻辑。

这些组合会产生一个0或1的结果，被称为“逻辑运算的结果”（RLO）。

位逻辑指令触发的逻辑操作可执行多种功能。

有位逻辑指令，履行下列职能：

---||---常开触点（地址）

---|/|---常闭触点（地址）

---（SAVE）将RLO保存到BR存储器

XOR异或

---（）输出线圈

---（＃）---中间输出

---|NOT|---反向功率流

下面的指令作出反应的RLO1：

---（S）设置线圈

---（R）复位线圈

SR设置复位触发器

RS复位设置触发器

其他指令的反应积极或消极的边缘过渡到履行下列职能:

---（N）---RLO负跳沿检测

---（P）---RLO正跳沿检测

NEG地址负边缘检测

POS地址正边缘检测
