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.
Sensor
0
1
2
3
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.
6.5.2

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%.
Output
0 Output 0 Value
1 Output 1 Value
2 Output 2 Value
3 Output 3 Value
6.5.3

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.
Output
0 Output 0 Name
1 Output 1 Name
2 Output 2 Name
3 Output 3 Name
The Output names are retained until a factory reset occurs.
It is strongly recommended that:
1. Spaces within the name should be replaced with the '_' character.
2. 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.
