Scaling

Parameters for scaling are added to each signal defined in the DBC file. These are

Factor
Offset
Minimum / Maximum.

In this context the DBC format refers to raw and physical values. The raw values are always transmitted on the CAN bus. The Prepared DBC Signals module shows the physical values, while the CAN Layer2 nodes show the raw values

Physical values and raw values are converted to each other in the following context:

Equations for the scaling

Scaling 1:

Scaling 2:

The physical values are limited to the specified range (Minimum/Maximum) after the calculation.
