The type of control performed by each Controller is selected by setting
the control mode. Setting the control mode sets default values for the
output assignments required for the control.
After setting the control mode, specify direct/reverse operation for each
channel.
Standard Models
The control modes that can be selected depend on the number of
input points.

Description
Control whereby the MV is increased as the present
value increases
(When the present value (PV) is higher than the set
point (SP), the MV is increased in proportion to the
difference between the PV and the SP.)
Control whereby the MV is decreased as the present
value increases
(When the present value (PV) is lower than the set
point (SP), the MV is increased in proportion to the
difference between the PV and the SP.)
