Displayable Signal Troubleshooting
==================================

The data dictionary outlines the type, accuracy, minimum, and maximum values
for a signal. If these parameters don't align with how the signal is actually
used in the application, the calibration tool might display the signal
incorrectly.

In ATI Vision
-------------

In ATI Vision, arrows appear to show that the value differs from the default.

In OpenECU Calibrator
---------------------

In OpenECU Calibrator, the color of the signal changes to indicate it's
different from the default value.

Resolution
----------

Typically, updating the accuracy, minimum, or maximum value in the data
dictionary resolves the issue. If not, consider setting the signal type in
the model explicitly using a Simulink data type conversion block.
