Using kernel messages for diagnosis

You can turn on kernel messages for your own diagnostic purposes or for Beckhoff Support. The kernel messages are displayed when booting from TwinCAT/BSD and stop at the error location. As a result, you or Beckhoff Support can locate errors.

Requirements:

Restart required. The kernel messages can only ever be turned on during the bootup.

Proceed as follows:

1. Start the Industrial PC.

2. Press the [Spacebar] during the boot process.
The boot process is paused.

3. Press button [6] to select option 6. Boot Options.
The Boot Options menu appears.

4. Press button [5] to activate option 5. Verbose: on.

5. Press [Enter] to conclude the procedure.

TwinCAT/BSD continues to boot up and the kernel messages are displayed. These settings are not saved. Repeat the work steps shown if you require the kernel messages again at the next start.
