Datalogger (G4224530)

The datalogger playback displays the filename of the recording being played on the screen’s header, alongside the Vehicle Identification Number (VIN) and the TOPIx cloud connection status.

The feature will avoid confusion when diagnostics involves reviewing multiple datalogger recordings. It allows you to keep track of which recording is being reviewed.

How to Use Datalogger Playback

1. Launch the Diagnostic Device Agent (DDA) and select Login when prompted.
2. Select one of the following:
   • a) If reviewing datalogger recordings and no vehicle is connected, select the DDA icon from the windows tool tray and select Start Datalogger
   • b) If a vehicle is connected, wait for the connection process to complete from the Option Selection Screen select Browse All
3. Select the Diagnostics tab at the top of the page.
4. In the Diagnostics tab, from the Vehicle Data Screen select the Datalogger icon.
5. From the right of the datalogger screen, select Replay.
6. From the file browser popup select your required recording. All datalogger recording files will have a json.gz file type.
7. The recording is now on the screen with playback options.

Close Datalogger Icon

An icon is available on the datalogger main page, visible in the top right corner of the screen. When the icon is selected, datalogger will close and TOPIx Cloud Diagnostics will automatically reconnect to the vehicle.

This will make switching between the TOPIx Cloud Diagnostics and datalogger much easier and more efficient.

Assign a Custom Name to Datalogger Recordings

You can assign a customized filename to a recording captured with datalogger.

This provides a popup on screen when a datalogger recording has been taken, allowing you to enter your filename, making it easier for you to distinguish between multiple recordings.

Datalogger global search function

The Global Search function allows you to search for a Parameter ID or Parameter Description from all modules listed.

With a VIN in session, enter the value to be searched in the new search bar at the top of the datalogger module list screen.

The search function also accepts partial search terms. For example, if Pressure is searched, then all parameters that contain the word Pressure from all modules will be presented on screen for selection.

Nominal values display

The nominal values for a parameter are published and pushed to all connected machines instantly.

Where a nominal value has been published for a parameter, there will be a shaded area on the graph view for that parameter, making it easy to identify a signal that is outside of the nominal value.

How to override the set nominal value

1. Select a parameter from the list of available parameters on the module list screen.
2. From the right-hand pane named Action, select Signal Settings.
3. The published nominal values for the parameter will be displayed in the Nominal Value Start text box and the Nominal Value End text box. If required, you can amend the nominal values in the text boxes.
4. When the datalogger is started, the new values that you have entered will be used.

Diagnostic Trouble Codes (DTC) to have related datalogger signals mapped to them

This feature allows JLR engineering to map Parameter Identifiers (PIDs) to DTCs, allowing Datalogger to be launched directly from a DTC, with the mapped PIDs pre-selected for logging.

This feature is only available from within a workflow, at Step 2 – Test plan. To use this functionality:

1. Start a Fault and Breakdown workflow.
2. Enter the symptoms associated with customer concern in step 1.
3. At step 2 of the workflow, navigate down to the Test Plan table and select ‘Investigate a DTC’.
4. A list of DTC's present on the vehicle will now be displayed. Select the DTC relevant to the vehicle concern.
5. This DTC will now be added to a new table below the Test Plan table. The DTC can be selected from this new table to view the DTC snapshot data and DTC help text.
6. The last column in the Data Logger table will show either a ‘Run’ button if the selected DTC has PIDs mapped against it. If no PIDs have been mapped then there will be text stating ‘No signals have been assigned to this DTC.
7. To learn how to clear and read DTCs, refer to this video: Clear and Read DTCs Per Module (from workflow)
8. To learn how to investigate DTCs and launch datalogger, refer to this video: Investigate DTC and launch Datalogger (from workflow)

PROVIDE AN ABILITY TO DELETE AND RENAME SAVED DATALOGGER TESTS IN DATALOGGER

This feature will allow you to delete and rename datalogger tests that have saved to your TOPIx cloud profile. Prior to this feature, when a datalogger test had been saved it was not possible to change the title or remove it.

1. You must be a registered user, logged into TOPIx.
2. Select  TOPIx Home Page  to open the vehicle search page.
3. Enter a VIN  from the Vehicle Search Page.
4. In the OPTION SELECTION menu select Fault and Breakdown.
5. Select  Diagnose a Fault.
6. Enter Symptoms (For example Body, Lighting, Exterior lighting, Headlamp Concern) then continue.
7. From the Test Plan Table, select Launch Datalogger.
8. When Datalogger has launched, from the right hand of the screen select Manage Tests.
9. A pop-up will appear showing all tests saved to your user profile.
   • a) To edit a datalogger test name, select the edit icon next to the test that needs to be edited
   • b) To delete a datalogger test, select the delete icon next to the test that needs to be deleted
