7.12.6 Flow transducer selection
The pressure actual values are read and scaled via the transducer interfaces. The parameter
<ActiveTransducerInterfaceAreaA> (0x230D[N]) keeps the number of the interface for the pressure in cylinder
A-side. If the pressure on A-side is rising, the cylinder has to move in positive direction.
The actual pressure on A-side is necessary for the flow control. The pressure in cylinder B-side is optional as
well as the system pressure and the tank pressure (corresponding interface numbers:
<ActiveTransducerInterfaceAreaB> (0x230F[N]), <ActiveTransducerInterfaceSystem> (0x2330) and
<ActiveTransducerInterfaceTank> (0x5217). All actual pressure values are filtered with a low pass filter.
