(Example 1)
If the PID ZONE type is SP, Working SP is 40.0 and like figure 3.13.2, T values are set,
because the SP is between T3(0) and T4(50) by the figure, Zone number for PID control is four.
So PID constants in ZONE 4 are operated for PID control.
(Example 2)
If the PID ZONE type is PV, the PV is 150.0 and like figure 3.13.2, T values are set, because
the PV is between T5(100) and T6(250) by the figure, Zone number for PID control is 6. So PID
constants in ZONE 6 are operated for PID control.
2. Segment PID
Segment PID is used for only program control and sets PID group number applied to
PID control in Segment edition screen of program. It is like figure 3.13.3.
