(4)時間繼電器的處理時間繼電器除了有延時動作的觸點外,還有在線圈通電瞬間接通的瞬動觸點。在梯形圖中,可以在定時器的線圈兩端并聯存儲器位的線圈,它的觸點相當于定時器的瞬動觸點。
(5)設置中間單元,在梯形圖中,若多個線圈都受某一觸點串并聯電路的控制。為了簡化電路,在梯形圖中可以設置中間單元,即用該電路來控制某存儲位,在各線圈的控制電路中使用其常開觸點。
(6)設立外部互鎖電路,由于軟件動作時間原因,即使在梯形圖已經完成互鎖,為確保不同時動作,還要在plc外部設置硬件聯鎖電路。
(7)外部負載的額定電壓,plc雙向晶閘管輸出模塊一般只能驅動額定電壓ac220v的負載,系統交流接觸器應換成220v電壓的線圈。
2.3 電機星角啟動轉換案例
以三相異步電動機星三角起動為例,示范具體轉換過程以及典型問題的處理。星三角起動繼電器控制電路原理圖如圖1(a)圖所示。plc系統i/o分配方案如下:輸入sb1對應x1,sb2對應x2,輸出km1、km2、km3分別對應y1、y2、y3。根據上述提供的方法以及注意事項得到plc梯形圖如圖1(b)圖所示。
由圖中可以看出,采用梯形圖可以適當設置中間環節(輔助繼電器m1),以使程序更加簡潔;元器件使用沒有數量限制,通斷狀態也不構成硬件成本,所以梯形圖設計中定時器t0一直保持通電狀態;對于km1(y1)與km2(y2)除了進行梯形圖互鎖之外還要進行硬件聯鎖,以確保其不同時導通。
