OpenBridge Tech Notes

OpenBridge fails to import PLX file


Product: OpenBridge
Version: All
Date Added: 2013-11-15


When using OpenBridge to modify PLX files, the number of waveforms in the imported PLX file must match the number of waveforms in the data block. They may differ if you use the "File" → "Export to New .PLX" option in Offline Sorter, which allows you to exclude waveforms in the exported PLX file. When importing one of these files into the tank, the new sort code will not be created. In v2.18 and prior, OpenBridge may erroneously report that the import completed.


Use the "File" → "Save" or "File" → "Save As" options in Offline Sorter to create PLX files for importing with OpenBridge. Do not use the "File" → "Export to New .PLX" option.

Events read from the tank are missing if there is a gap in the data

In order to save time, the TTank server will stop searching for data that matches the requested criteria if there are no matches in the last 1 million events. If the data is sparse and there is a large gap, the data after the gap might not be extracted.


Note: This solution is only valid in v2.16 and above.

To override the search limiting feature and force the tank to search the entire block for data on each channel, you must manually enter a registry key:

  1. Run the Registry Editor (regedit.exe).



    For 64-bit machines, the registry path is HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\TDT\TTank

  3. Right-click the right pane, point to New and click DWORD (32-bit) Value on the shortcut menu.

  4. Name the new entry SEARCHLIMIT.

  5. Right-click SEARCHLIMIT and click Modify on the shortcut menu.

  6. Enter a Value data of 1.

  7. Click OK.

  8. The TTank server will now search until the end of the block for events instead of performing a quick search.

To restore default behavior:

  1. Use the Registry Editor to browse to the SEARCHLIMIT DWORD (32-bit) Value you created and delete the entry or set to 0.
