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)
T/|---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

---||---(常开触点)指定的<address〉是位值存储在关闭时等于“1”。
当触点闭合时,阶梯铁路电源流经的联系和逻辑操作(RLO)=“1”的结果。
否则,如果信号在指定<address啲状态是“0”,联系人是开放的。
当接触是开放的,功率不流经的联系和逻辑操作(RLO)=“0”的结果
