The structure of the process data part of the input and output data area depends
on the chosen message telegram. Applicable configurations are described below.
When selecting a message telegram, ascertain what output format of the measured
value (integer/float) is required and whether a parameter channel is needed or not.
The gauge can also be operated in such a way that the master does not transmit
any output data to the slave.
