Input Range (configuration bits 1–3)
Use this bit field to configure the channel for the type of input device you want to
connect to your module.
Data Format (configuration bits 4–6)
Use this bit field to select one of the following formats:
Engineering units (mV or nA).
•
Scaled for PID (works with the SLC PID instruction).
•
Proportional counts (two's complement binary).
•
1746-NI4 compatible format (the format used by the 1746-NI4).
•
User-defined scale A.
•
User-defined scale B.
•
These data formats are defined in the following table.
