Channel Configuration, Data, and Status 5-9
The channel data word contains a 16-bit integer that represents the
value of the analog input channel. The tables below show the channel
data word values for various input types and data formats. The second
table shows the default full-scale values for the proportional counts
data format. The table does not imply the entire data value range is
usable resolution.
