提示
- High Limit 應(yīng)該 >= Low Limit；
- SETRANGE LOW≤SETRANGE HIGH
- SETPOINT LOW ≤ SETPOINT HIGH
- SETRANGE LOW≥SETPOINT LOW
- SETRANGE HIGH ≤ SETPOINT HIGH
如果SET VALUE TYPE（設(shè)定值類型）是SET PNT，則只有“SET RANGE HIGH”可編輯，且“SET RANGE HIGH”的值自動復制到“SET RANGE LOW”。
從R3.06起，CV設(shè)定范圍有四種類型，Set Range – Zone Control（設(shè)定范圍-區(qū)域控制），Set Point – Setpoint Control（設(shè)定點-設(shè)定點控制），Low Limit Zone Control（低限區(qū)域控制），在CV上只有下限（無上限）和High Limit Zone control（高限區(qū)域控制）只有高限（無低限）。在DEF文件中為每個CV定義了SETVALUETYPE。
即使為每個限制分配了位號名，也會執(zhí)行上述錯誤檢查。檢測到錯誤時，數(shù)據(jù)變?yōu)锽ad。（R4.02）
**為了將Online Tuning Weight（在線整定權(quán)重）反映到控制器，應(yīng)從控制面板觸發(fā)在線整定。然后在下一個執(zhí)行周期得到修改。
B12經(jīng)濟函數(shù)視圖
Economic Function (EF)（經(jīng)濟函數(shù)）參數(shù)顯示在Economic Function（經(jīng)濟函數(shù)）面板上。可以在PCTP離線定義多個經(jīng)濟函數(shù)。在此面板上，操作員可以選擇經(jīng)濟函數(shù)并輸入控制器的EF參數(shù)。
經(jīng)濟函數(shù)面板有“ENG”和“OPE”兩種操作模式。以下是ENG模式的窗口。

TIPS
- High Limit should be >= Low Limit
- SETRANGE LOW≤SETRANGE HIGH
- SETPOINT LOW ≤ SETPOINT HIGH
- SETRANGE LOW≥SETPOINT LOW
- SETRANGE HIGH ≤ SETPOINT HIGH
If the “SET VALUE TYPE is SET PNT then only “SET RANGE HIGH” is editable and value of “SET RANGE HIGH” is copied to “SET RANGE LOW” automatically.
From R3.06, there are 4 type of CV set range, Set Range – Zone Control, Set Point – Setpoint Control, Low Limit Zone Control with only low limit (no high limit) on CV, and High Limit Zone control with only high limit (no low limit) on CV. SETVALUETYPE is defined in the DEF file for each CV.
The above error check is also done even when the tag name is assigned to each limit. The data becomes Bad when the error is detected. (R4.02)
** In order to reflect Online Tuning Weight to the controller, Online tuning should be triggered from the control panel. Then the modification is reflected at the next execution period.
B12. Economic Function View
Parameters of Economic Function (EF) are displayed on the Economic Function Panel. Multiple Economic functions can be defined on PCTP offline. On this panel, operators can select the economic function and enters the EF parameters for the controller.
Economic Function Panel has two modes of operation, “ENG” and “OPE”. Following are the windows for the ENG modes.
