描述

1.連續(xù)執(zhí)行與脈沖執(zhí)行

功能指令有連續(xù)執(zhí)行和脈沖執(zhí)行兩種類型。如圖1所示，指令助記符MOV后面有“P”表示脈沖執(zhí)行，即該指令僅在X1接通（由OFF到ON）時執(zhí)行（將D10中的數(shù)據(jù)送到D12中）一次；如果沒有“P”則表示連續(xù)執(zhí)行，即該在X1接通（ON）的每一個掃描周期指令都要被執(zhí)行。

圖1功能指令的執(zhí)行方式與數(shù)據(jù)長度的表示

2．數(shù)據(jù)長度

功能指令可處理16位數(shù)據(jù)或32位數(shù)據(jù)。處理32位數(shù)據(jù)的指令是在助記符前加“D”標志，無此標志即為處理16位數(shù)據(jù)的指令。注意32位計數(shù)器（C200～C255）的一個軟元件為32位，不可作為處理16位數(shù)據(jù)指令的操作數(shù)使用。如圖3-27所示，若MOV指令前面帶“D”，則當X1接通時，執(zhí)行D11D10→D13D12（32位）。在使用32位數(shù)據(jù)時建議使用首編號為偶數(shù)的操作數(shù)，不容易出錯。
