2)
For the outputs „0V active" or „24V active" is selectable in the device configuration. This has also effect to the I/O
outputs.
3)
The „Dummy Function" sets the output „Function result" only. This was implemented due to reasons of compatibility.
4)
The output of the measured value is done in dependency of the chosen unit of measure at the fieldbus output and
the type of sensor:
Measuring unit

inch
5)
This function is implemented only in L20-3-XX-S (L20-XX-S in preparation).
Bytes 21 to 23:
Bytes 21 to 23 are reserved for future extensions.
