Navigation: CPA > Tools > Configuration Tool > # Compare |

The Compare tool enables users to identify differences in configurable parameters. It supports the following comparison modes:

•Diagnostic File vs. Diagnostic File:

oCompare two saved diagnostic files to identify configuration changes or discrepancies.

oAt least one of the Diagnostic Files needs to be created with a CPA version 4.3.0 or above to ensure configuration data is available.

•Connected Device vs. Connected Device:

oEvaluate the settings of two connected controllers to ensure uniformity across devices.

•Connected Device vs. Diagnostic File:

oCross-check a controller’s current configuration against a reference diagnostic file to verify compliance or detect modifications.

oThe diagnostic file can also be created with older versions, as configuration data is retrieved directly from the connected device.

## How to use:

•Source selection:

ouse the source drop-down menus to select the inputs for comparison.

▪to select a diagnostic file, it must first be loaded using the Load button.

•Start comparison:

oclick the Compare button to initiate the analysis.

## Output:

The tool generate a list of configurable parameters that differ between the selected sources, helping users to quickly identify and resolve configuration mismatches.

For parameters of the type <Array>, double-click the entry to view the differences at the individual index level.

Indicating a "--" in one of the sources indicates that this parameter is not existing (or inactive) within that source.
