運算速度高速化也是日本PLC系統(tǒng)追求的一個重要目標。由于目前PLC的CPU模塊競相采用32位RISC芯片,運算速度大為提高。一般基本指令的執(zhí)行速度均達到數(shù)十個納秒(ns),如三菱電機的Q02HCPU其輸入指令的執(zhí)行時間為34ns,富士電機MICREX-SX系列SPH300達20ns,橫河電機的FA-M3系列的F3SP59-7S其輸入指令的執(zhí)行時間為17.5ns。僅看一種指令的執(zhí)行時間并不能完整地說明問題。日本電機工業(yè)會(日本電機工業(yè)的行業(yè)協(xié)會)JEMA一直倡導(dǎo)用PCmix值(即PLC的處理時間性能表示指標,用1微秒執(zhí)行的基本指令和數(shù)據(jù)處理指令的平均次數(shù)來表示)來衡量PLC的運算速度。所謂1微秒執(zhí)行的基本指令和數(shù)據(jù)處理指令的平均次數(shù),是按PLC應(yīng)用程序所使用的指令的頻繁程度的統(tǒng)計平均值計算的。
