@Jan-Reitinger Thanks for explanation! I promise I will study the documentation in more details next time. However, still I have some remarks here.
Regarding SAT documentation:
"The maximal rate at which the active limits may vary is given by time constants tp (positive slope) and tn (negative slope)."
This statement is ambigous for me.
If we say maximal rate of the signal is affected by some parameter rate_max, then from technical point of view, higher
rate_max means higher allowable rate (1st derivative), thus indicating being close to immediate changes of the signal.
So if rate_max reaches infinity, immediate changes are allowed.
Then we should say the maximal rate at which the active limits may vary is given by INVERSE OF time constants tp,
and rate_max = 1/tp, meaning that the meaning of logic in choice of parameters tp and tn is actually inverse.
This is actually declared in the documentation of RLIM block as the steepest rise per second, and should be also repeated for for documentation of SAT to keep documentation consistent.
I tried series connection of CNR and RLIM, and changing CNR on the fly. If tp=0.1, then maximal slope is 10, and the new value of CNR is
reached in 0.1s, following linear ramp signal. This is OK, and similar functionality works for SAT block.
Also, reading "time constants tp and tn" may indicate presence of some dynamics like first-order system 1/(tp*s+1) or 1/(tn*s+1), because this technical term is ususally used
when talking about dynamic systems. It would be much better to simply use "parameters tp and tn" instead to make things clear.
