7.5.7 Object 0x2418: Controller output
This parameter holds the controller output of the pressure controller.
7.5.8 Active parameter set number
The pressure controller contains objects to influence the control behavior.
To adapt the control behavior to different control conditions within the machine cycle, 16 parameter sets are
provided. Within these sets most of the controller parameter can be configured.
Only one of the 16 parameter sets is used at the same time. The parameter set to be used is selected by
<ActiveParameterSetNumber> (0x2350). This parameter defines the parameter set number of the objects
which is used for the pressure controller. The following table shows all pressure controller objects that are part
of one parameter set.

Table 81: Pressure controller objects contained in a parameter set
The objects which are part of the parameter set are signed with a sub-index N (1…16) in brackets
after the index number. E.g. (0x2304[N]).
