Description
CONTOL ABORT,
SEE MSGS
Optimization error encountered. Select [STATUS MESG] on the Menu Bar to read the error.
CL ERROR
Control Language error on the Profit Optimizer point.
COORDINATING
The optimizer is indicating that it has encountered competing objectives and that bringing all
variables within constraints cannot be managed at the current execution, or cannot be managed
within the prescribed horizon.
CAUTION
Competing constraints are usually temporary conditions, provided that operating conditions have not
changed since last tuned.
It remains your responsibility, however, to know what is going on with your process and when manual
intervention is required.

Optimizer point is shut OFF. Profit Optimizer is not tracking the CVs, is not executing calculations,
and is not controlling the MVs.
INITIALIZING
Optimizer is aligning itself with current process conditions and running integrity checks on points.
OFF
Optimizer is receiving input from the process and making prediction calculations, but there is no
controller output.
ON
Optimizer is running (without optimization).
OPTIMIZING
Optimizer is running, and the control objectives at the current execution have been met. Profit
Optimizer is now attempting to optimize the process based upon the economic objectives.
