提示

• High Limit 应该 >= Low Limit；

• SETRANGE LOW≤SETRANGE HIGH
• SETPOINT LOW ≤ SETPOINT HIGH
• SETRANGE LOW≥SETPOINT LOW
• SETRANGE HIGH ≤ SETPOINT HIGH
  如果SET VALUE TYPE（设定值类型）是SET PNT，则只有“SET RANGE HIGH”可编辑，且“SET RANGE HIGH”的值自动复制到“SET RANGE LOW”。
  从R3.06起，CV设定范围有四种类型，Set Range – Zone Control（设定范围-区域控制），Set Point – Setpoint Control（设定点-设定点控制），Low Limit Zone Control（低限区域控制），在CV上只有下限（无上限）和High Limit Zone control（高限区域控制）只有高限（无低限）。在DEF文件中为每个CV定义了SETVALUETYPE。
  即使为每个限制分配了位号名，也会执行上述错误检查。检测到错误时，数据变为Bad。（R4.02）
  **为了将Online Tuning Weight（在线整定权重）反映到控制器，应从控制面板触发在线整定。然后在下一个执行周期得到修改。

B12经济函数视图

Economic Function (EF)（经济函数）参数显示在Economic Function（经济函数）面板上。可以在PCTP离线定义多个经济函数。在此面板上，操作员可以选择经济函数并输入控制器的EF参数。
经济函数面板有“ENG”和“OPE”两种操作模式。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.
