3-10 Module Data, Status, and Channel Configuration
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.
