Accessing Log Files
When troubleshooting problems with the REV Control System log files provide indicators of what the status of the Control Hub or Expansion Hub were during an event. Often the first log that is considered is the Robot Controller log, as they are relatively easy to decipher and can be pulled from the Control Hub or Robot Controller. While working through the troubleshooting process looking through the XML files, Wi-Fi Log, or Updater Logs in addition to the Robot Controller logs help to paint a full picture.
There are a few ways to access the log files depending on if you are looking to troubleshoot or downloading the log files for REV support to help.
Log Viewer - REV Hardware Client
The REV Hardware Client has a Log Viewer that makes it easier to parse overall log files. Through a series of filters, tags, and a search function makes it easy to see what is happening on the Control Hub or Driver Hub during any opmode run.
To access the Log Viewer, head to the Utilities Tab.
From there you can select and open log files for connected devices or for ones downloaded onto the computer.
Downloading Log Files
When sending logs to REV Support use the REV Hardware Client. The Client will zip all relevant log files, collect some additional information from a form, and then send them to REV for diagnosis. When running through the troubleshooting process at an event, physically connecting to a Control Hub (REV-31-1595) and using the file search of the computer allows access to the files. Alternatively connecting to the Robot Controller Console allows downloading the logs through the manage tab.
REV Hardware Client

- 2.Plug the USB-C Cable into the top board of the Control Hub and into a PC with the REV Hardware Client installed.

There is a short form to fill out with additional information to help REV Support troubleshoot the issue.
