Module Data, Status, and Channel Configuration
4-9
Raw/Proportional Data Format
The raw/proportional data format provides the greatest resolution of all
the data formats. For this format, the value presented to the controller is
proportional to the selected input. It is also scaled to the maximum data
range allowed by the bit resolution of the A/D converter and selected
filter frequency.
If you select the raw/proportional data format for a channel, the data
word will be a linearized number between -32768 and +32767. The value
-32768 corresponds to the lowest temperature value for an RTD or the
lowest resistance value for a resistance device.
