這是我個(gè)人的心得,請大家指教,指出是否哪裡有錯誤,
或者觀(guān)念上可以改進(jìn)或補充的地方
希望大家能多多討論,謝謝


PLC程式思路步驟


1.先確認動(dòng)作流程,規劃出
  初始階梯圖(判斷:何時(shí)跳到主流程,過(guò)載流程,警報流程),
  主流程(步進(jìn)階梯圖STL),
  過(guò)載警報流程(步進(jìn)階梯圖STL),
  其他警報流程(步進(jìn)階梯圖STL),
  EMS流程(步進(jìn)階梯圖STL)


2.規劃出I/O元件,暫存器,計時(shí)計數器,數量與配置


3.盡量將觸發(fā)條件重複性高之輸出(如:指示燈)統一寫(xiě)在初始階梯圖上


4.程式完成後注意流程之間,輸入輸出之間的互鎖與互相保護
