What is the difference between ModSoft PID function and Concept PID function.

PB - Gain = 100 / PB

I - Integral Coefficient Expressed as Repeats/Minute. The higher the value, the greater the integral contribution

D – Derivative Coefficient. Expressed in Minutes. The higher the value, the greater the derivative contribution

GAIN - Enter GAIN value as a REAL. Can be Positive or Negative. Positive Gain = Direct acting loop. Negative Gain = Reverse acting loop

TI - Integral Time. Expressed as TIME. The smaller the unit of time, the more significant the integration

TD - Derivative Time. Expressed as TIME. The greater the unit of time, the greater the derivative contribution.
