Scaling Minimum / Maximum Values
When Input Mapping is used the user may specify the input signal range through the Input Minimum and
Input Maximum parameters. There is one pair of registers for each of the 4 possible outputs.

When either the Low Scale or High Scale value changes, an internal calculation is performed to calculate
the linear transformation to be applied to the sensor reading.
Output Values
Outputs use
float
values which represent the percentage of full scale. If the output is not mapped, the value
written (0
–
100%) is identical to the value that is read back. If the output is mapped, the scaling values are
used to transform the minimum input value to 0% and the maximum input value to 100%. (see Sensor
Scaling).

Output Names
Each output has a name. The default names for the outputs are
Output_0
through
Output_3
. The default
names may be overwritten, such as ‘Stack_Lite’ or ‘Control_Valve’. Names
are restricted to 16 characters.

The Output names are retained until a factory reset occurs. It is strongly recommended that:
3)
Spaces within the name should be replaced with the ‘_’ character.
4) All output names on a particular device are unique
–
if duplicate functions are supported
append a ‘_x’ string, where x represents the instance. For example,
Stack_Lite_1
and
Stack_Lite_2
could be used if 2 stack lights are being connected.
