User Notes
Combined
Constraint #
Read-Only No Access
Number of the combined constraint in the optimizer.
Linear Obj Coef
Target ENG
Linear objective coefficient. An optimization parameter.
Quad Obj Coef
Target ENG
Quadratic objective coefficient. An optimization parameter.
Desired CC
Value
Target ENG
Desired resting value for the combined constraint during
quadratic optimization.
CC LO Error
Weight
Target ENG
Establishes control priorities at low limits when it is physically
impossible to keep all combined constraints at setpoint or within
a range.
Used in conjunction with the scaling
factor. Increasing the weight
increases the priority. Combined
constraint errors with higher error
weights get corrected first.
CC HI Error
Weight
Target ENG
Establishes control priorities at high limits when it is physically
impossible to keep all combined constraints at setpoint or within
a range.
Used in conjunction with the scaling
factor. Increasing the weight
increases the priority. Combined
constraint errors with higher error
weights get corrected first.
Opt Error Tol
Target ENG
The allowable deviation past the low or high limit before
optimization halts and constraint handling begins.
Application Notes
The following information can help you use the Profit Optimizer Comb
Constraint Detail display:
• See Application Notes for the CV or MV Summary displays in Section 4 to see
how Profit Optimizer defines near limits for predicted values.
• For a descriptive message about a parameter and its CDS location, touch the
parameter name (the field, not the target). Select
CLR
to clear the message.
