Occasionally you may be asked for a hardware log backup from Omron for diagnostic purposes. You can obtain this using a separate tool in the Sysmac Studio install directory.
These files must be read with a special tool by Omron. So unfortunately you cannot inspect these files yourself.
1) Navigate to the ControllerLogUuploadTool folder in your sysmac install directory and open the ControllerLogUploadTool. The default install path is C:\Program Files\OMRON\Sysmac Studio\ControllerLogUploadTool
2) Either type in the IP of your controller or browse for it using the button to the right of the entry field. Select the log types required and click upload
3) Click the path that has just been generated to open the path in explorer
4) Send everything in this folder to your Omron representative
