▶ DELAY TIME 是在【10.7 继电器设定画面】被设置的时间。

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

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

▶ 根据PV值来判断ON/OFF SIGNAL 动作
设定	ON/OFF SIGNAL 动作
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设置画面

[图面10-8] IS设定画面

1. TARGET：选择要使用的IS 对象。

2. TYPE：选择要使用的IS 种类。

3. BAND：选择内部信号的动作方向。

4. IS RANGE & DELAY：

1. 范围低：设定内部信号的下限值。

2. 范围高：设定内部信号的上限值。

3. 延时：设定内部信号的延迟时间。

☞ 在定值运行中，如果设置了变化率(SLOPE)，“TSP”的动作就是与程序控制的“TSP”一样，如果不设置变化率(SLOPE)，“TSP”作为“SP”来动作。

在BAND=INB的条件下	在BAND=OUTB的条件下

☞ 如果TYPE选择PV，就会存在回差（不能变更）的滞后现象
