The initial result is entered in the units specified by the input type during configuration (ohms
for resistance input). This is the actual field result floating point value to the instrument when
an input block is in auto. This is a writeable floating point data value when the module block is
in manual or the I/O is locked.
Writeable data is entered as a floating point representation of a count value for VCIM and TIM
modules. The signal equivalents for the floating point values are:

**Active current input module source.
Writeable data is entered as a floating point representation of a count value for RIM and
WRIM modules. The signal equivalents for the floating point values are scaled between 0 and
50,000 using 0.08 ohms per count for RIM and 0.008 ohms per count for WRIM. Some
sample values are:
Floating Pt. Value RIM WRIM
50000.0 4000 400
25000.0 2000 200
6250.0 500 50

This data quality field will go BAD if any of the blocks diagnostic errors becomes active while
the block is in auto.
