PLC運(yùn)行正常時(shí),掃描周期的長(zhǎng)短與用戶應(yīng)用程序的長(zhǎng)短、CPU的運(yùn)算速度、I/O點(diǎn)的情況等有關(guān)。通常用PLC執(zhí)行1KB指令所需時(shí)間來說明其掃描速度(一般1-10ms/KB)。值得注意的是,不同指令執(zhí)行時(shí)間是不同的,故選用不同指令所用的掃描時(shí)間將會(huì)不同。若用于高速系統(tǒng)要縮短掃描周期時(shí),可從軟硬件上同時(shí)考慮。PLC周期性循環(huán)掃描工作方式的顯著特點(diǎn)是:可靠性高、抗*力強(qiáng),但響應(yīng)滯后、速度慢。
