PID function
Among XC series PLC special modules, digital input module (A/D module) and temperature
control modules both have PID control function. The four parameters (Kp, Ki, Kd and Diff) should
be set.
a.) Parameter P is the proportional parameter, acts on the difference between the actual process
value and the target value.
b.) Parameter I is integral parameter, used to remove the offset.
c.) Parameter D is derivative parameter, used to control signal’s changing trend speed.
