6.3.14.5 Example 4: Adjust transducer interface with scaling
1. Select the transducer interface which is intended to be adjusted.
Therefore set the <InterfaceNumber> (0x6201).
2. Define the input signal for the transducer interface with the input parameter address.
Get the index, sub-index and parameter length in bits from the object dictionary or from the parameter
description.
For example, the analog input 2 <ActualValue2> (0x6211) should be used as input:
Build the address value in the following manner:
Write the result 0x00030010 in the parameter <TransducerPort> (0x4032).
3. Check transducer interfaces <Sign> (0x6203) and change value (1 or –1) if needed.
4. Set transducer interface <Type> (0x6202) to 2 (pressure transducer).
5. Set the <PressureOffset> (0x6223) to 0.
6. Define the scaling of the linear function by using two points with their coordinates
(x

, y

). The y values correspond to the output (normally the pressure) and the x values corre-
spond to the mapped input signal.
