1.12 PID control
With PLC function, PID set point/PID deviation value, PID process value can be set by
setting Pr. 128.
Performing the PID operation using the value of D9248 and D9249 as PID set point/
PID deviation value, PID process value, manipulated variable is stored to D9250.
When performing PID control with PLC function, "1" is set on D9255 instead of X14
signal.
