I have a doubt about the behavior of the "realistic" instruction in the device simulator.
The syntax is:
realistic(setPoint, proportion, integral, derivative, repeat)
I understand the setPoint and repeat parameters, but, since I am not a PLC / Control guy I don't understand the Proportion, Integral and Derivative parameters.
I know there is a big therory behind those concepts, but I'd like to know if there are some general rules, or pointers, something like:
- X controls the variability or amplitude,
- Y controls the frecuency,
- Don't use a value greater than A for parameter B
Thank you
