例如,需時(shí)10小時(shí)或36000秒的慢速過(guò)程達(dá)到63%時(shí)其采樣周期應(yīng)為40秒或稍長(zhǎng)些。如其過(guò)程不是特別快,通常不必要求使用0采樣周期來(lái)處理每次PID掃描的PID運(yùn)算。如果很多PID回路都使用大于掃描時(shí)間的采樣周期的話.則若許多回路可在同時(shí)結(jié)柬處理運(yùn)算時(shí),可以設(shè)置較寬的PLC掃描時(shí)間變化范圍。最簡(jiǎn)單的解決辦法是通過(guò)一一個(gè)設(shè)置為0的位數(shù)組進(jìn)行排列一個(gè)或多個(gè)位，使電流傳至各單個(gè)PID模塊。
