▶ DELAY TIME 是在【10.7 繼電器設定畫麵】被設置的時間。

▶ LSP = LOW SP，MSP = MIDDLE，HSP = HIGH SP，NPV = NOW PV，NSP = NOW SP。

▶ LD = LOW DIFFERENCE，HD = HIGH DIFFERENCE，T = ON/OFF SIGNAL。

▶ 根據PV值來判斷ON/OFF SIGNAL 動作
設定	ON/OFF SIGNAL 動作
① NPV < LSP ▶ ALWAYS : OFF
② LSP <= NPV < MSP ▶ NPV >= NSP–LD : ON ▶ NPV < NSP–LD : OFF
③ MSP < NPV <= HSP ▶ NPV >= NSP + HD : ON ▶ NPV < NSP + HD : OFF
④ NPV >HSP ▶ ALWAYS : OFF

10.5 IS設置畫麵

[圖麵10-8] IS設定畫麵

1. TARGET：選擇要使用的IS 對象。

2. TYPE：選擇要使用的IS 種類。

3. BAND：選擇內部信號的動作方向。

4. IS RANGE & DELAY：

1. 範圍低：設定內部信號的下限值。

2. 範圍高：設定內部信號的上限值。

3. 延時：設定內部信號的延遲時間。

☞ 在定值運行中，如果設置了變化率(SLOPE)，“TSP”的動作就是與程序控製的“TSP”一樣，如果不設置變化率(SLOPE)，“TSP”作為“SP”來動作。

在BAND=INB的條件下	在BAND=OUTB的條件下

☞ 如果TYPE選擇PV，就會存在回差（不能變更）的滯後現象

▶ 根據設定值來判斷INNER SIGNAL 動作
