Low_Input, Low_Value, High_Input, High_Value settings are used by the YUAA firmware to define the linear relationship between mA and customer-defined engineering
units. The I/O Point value will be in Engineering units. Engineering units are specific to the field device being used.

A diagnostic alarm is sent
if the field device ID differs
from this value and the
value is non-zero. This
value can be uploaded
from the YUAA if the field
device is connected.
