Hi,

You are not using the original Wago runtime, but the CODESYS Control for PFC 200 SL runtime from Codesys. This runtime has a different authentication system. With the first login after installing the runtime you had to enter login data.

Check here how to reset the login data.

Ok, I did not test it. It seems this option is only available when your are logged in :slight_smile:

This is now tested:

  1. Connect via ssh to the controller with the root user.
  2. stop runtime: sudo /etc/init.d/codesyscontrol stop
  3. cd /var/opt/codesys/
  4. rm .UserDatabase.csv
  5. rm .UserDatabase.csv\_
  6. rm .GroupDatabase.csv
  7. rm .GroupDatabase.csv\_
  8. rm .UserMgmtRightsDB.csv
  9. start runtime: sudo /etc/init.d/codesyscontrol start

With next connect to the controller you will asked to enter new credentials.

Hi,

You were still in the root user home directory.

cd /var/codesys/ vs cd /var/opt/codesys/

that’s why you get No such file or directory

you can check after cd command if the files are in the directory with either ls -la or ll

Im still new to this, so thank you for the help so far. So from what i can understand i need to go into putty connect to the pfc200 but the next step i dont understand how to change directory

cd means change directory

you need only to enter what is marked like this

rm means remove

You can also use WinSCP instead of ssh (Putty) to delete the files. But there you have set it to show hidden files with shortcut CTRL+ALT+h
