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:
