7.5.10.5 Object 0x585E: Cylinder rod diameter B
The rod diameter is necessary to calculate the force of the cylinder.
The units used must be consistent with the parameter units of the parameters <CylinderPistonDiameter>
(0x585F) and <CylinderRodDiameterA> (0x585D).
7.5.11 Actual value filter
The parameters <ActualPressureFilterCutoffFrequency> (0x23F2) and <ActualPressureFilterOrder>
(0x23F3) are used to set the behavior of the Butterworth filter. <ActualPressureFilterCutoffFrequency>
(0x23F2) specifies the cutoff frequency of the filter in Hz. The order of the filter is set with the parameter
<ActualPressureFilterOrder> (0x23F3) (possible values: 1…3).

7.5.11.1 Object 0x23F2: Actual pressure filter cutoff frequency
This parameter specifies the cutoff frequency of the Butterworth filter in Hz.
The value 0.0 disables the filter.
7.5.11.2 Object 0x23F3: Actual pressure filter order
This parameter sets the order of the Butterworth filter.
