4-8 Configuring the Module

Data Format (configuration bits 4 to 6)

Use this bit field to select one of the following formats:

1746-NO4 compatible format (the format used by the 1746-NO4)

engineering units (mV or nA)

scaled for PID (works with the SLC PID instruction)

proportional counts (two’s complement binary)

user-defined scale

These data formats and ranges are defined in the following table:
