The CC instruction controls a single process variable by manipulating as many as
three different control variables. As an option, any of the three outputs can be
used as an input to create feed forward action in the controller. The CC calculates
the control variables (CV1, CV2, and CV3) in the auto mode based on the PV -
SP deviation, internal models, and tuning.
