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.
