西門子PLC基本指令功能介紹
一、標(biāo)準(zhǔn)觸點(diǎn) LD、A、O、LDN、AN、ON、
LD，取指令。表示一個(gè)與輸入母線相連的常開接點(diǎn)指令，即常開接點(diǎn)邏輯運(yùn)算起始。
LDN，取反指令。表示一個(gè)與輸入母線相連的常閉接點(diǎn)指令，即常閉接點(diǎn)邏輯運(yùn)算起始。
A，與指令。用于單個(gè)常開接點(diǎn)的串聯(lián)。
AN，與非指令。用于單個(gè)常閉接點(diǎn)的串聯(lián)。
O，或指令。用于單個(gè)常開接點(diǎn)的并聯(lián)。
ON，或非指令。用于單個(gè)常閉接點(diǎn)的并聯(lián)。
二、正、負(fù)跳變 ED、EU
ED，在檢測(cè)到一個(gè)正跳變（從OFF到ON）之后，讓能流接通一個(gè)掃描周期。
EU，在檢測(cè)到一個(gè)負(fù)跳變（從ON到OFF）之后，讓能流接通一個(gè)掃描周期。
三、輸出 =
=，在執(zhí)行輸出指令時(shí)，映像寄存器中的指定參數(shù)位被接通。
四、置位與復(fù)位指令S、R
S，執(zhí)行置位(置1)指令時(shí)，從bit或OUT指定的地址參數(shù)開始的N個(gè)點(diǎn)都被置位。
R，執(zhí)行復(fù)位(置0)指令時(shí)，從bit或OUT指定的地址參數(shù)開始的N個(gè)點(diǎn)都被復(fù)位。
置位與復(fù)位的點(diǎn)數(shù)可以是1-255，當(dāng)用復(fù)位指令時(shí)，如果bit或OUT指定的是T或C時(shí)，那么定時(shí)器或計(jì)數(shù)器被復(fù)位，同時(shí)當(dāng)前值將被清零。
五、空操作指令NOP
NOP指令不影響程序的執(zhí)行，執(zhí)行數(shù)N（1-255）。
