Adaptation of the pressure controller parameters (kp, Tn)

Depending on control differences the pressure controller parameters can be dynamically
changed during the operating time.
Figure 11:
Enter the control differences for which there should be a change in the pressure control
parameters. 
The control differences must be entered in ascending order. If entered incorrectly, all pa-
rameters are set to 1111..4444 and have to be re-entered.
The other parameters assigned to the control differences such as kp or Tn can be en-
tered.
It is possible to activate an interpolation between the values in order to provide a contin-
uous adaptive function between all entered values. 
Enable this function with bit 5 = 1 in ZP177.3–.
The filter order pressure controller adaption can be set to smooth the control deviation via
ZP177.205–.
