西门子PLC基本指令功能介绍

一、标准触点 LD、A、O、LDN、AN、ON、 

LD，取指令。表示一个与输入母线相连的常开接点指令，即常开接点逻辑运算起始。

LDN，取反指令。表示一个与输入母线相连的常闭接点指令，即常闭接点逻辑运算起始。

A，与指令。用于单个常开接点的串联。

AN，与非指令。用于单个常闭接点的串联。

O，或指令。用于单个常开接点的并联。

ON，或非指令。用于单个常闭接点的并联。 

       二、正、负跳变 ED、EU 

ED，在检测到一个正跳变（从OFF到ON）之后，让能流接通一个扫描周期。

EU，在检测到一个负跳变（从ON到OFF）之后，让能流接通一个扫描周期。 

三、输出 = 

=，在执行输出指令时，映像寄存器中的指定参数位被接通。 

四、置位与复位指令S、R 

S，执行置位(置1)指令时，从bit或OUT指定的地址参数开始的N个点都被置位。

R，执行复位(置0)指令时，从bit或OUT指定的地址参数开始的N个点都被复位。

置位与复位的点数可以是1-255，当用复位指令时，如果bit或OUT指定的是T或C时，那么定时器或计数器被复位，同时当前值将被清零。 

五、空操作指令NOP   

NOP指令不影响程序的执行，执行数N（1-255）。
