Reset the Controller to Factory Settings

• 
  
• Performing a factory reset of the controller should be considered very carefully.
  The reset erases everything: User data files, the application, the controller IP address, any retain variables, passwords, shared directory settings, and all log files.

The reset is performed using these methods:

• From the File System tab of the Web server while the drive is running.
  • This method is recommended due to its ease of use.
• Selecting the function from the B3 Menu Button.
  • This can be done during the boot sequence or while the drive is running.

After two seconds (or longer if pressed during power-up), the 7-segment display on the controller is changed to an animation pattern indicating the factory reset has started.

After the factory reset is complete, the controller is powered down and restarted automatically.

Factory Reset Changes

The changes which occur during a reset are:

Erased Items

• User data files.
• Any application previously downloaded.
• Retained variables.
• Shared directory settings.
• Log files.

Defaults Restored

• Password for both the web page and SSH login.
  • See SSH Login to a Controller and User Authentication.
• Controller network configuration.
  • Examples: IP address, Subnet, and Gateway settings.
• Auto-Start option.

PCMM2G Only

• The SSH keys are regenerated.
  • SSH clients logged on during the factory reset are forced to log in again.
  • All Date and Time settings are reset to default (NTP enabled).

Notes

• The factory reset cannot be performed while an application is running.
• Do not turn off the controller during the reset procedure.
• If the AKD PDMM or PCMM has just been powered up, the B3 button must be held down much longer than 2 seconds.
  • In this case, hold down the button until the 7-segment display shows the B3 menu.
  • See B3 Menu Button.
• Estimated time for factory reset:
       AKD PDMM and PCMM: 4-5 minutes.
       PCMM2G: About a minute.
  • The 7-segment display on the controller is animated during this process.
• After the factory reset is complete, the controller is powered down and restarted automatically.
• After the controller is restarted, the controller IP address may change based on the controls rotary switch.
  • If the rotary switch is at position 0 (zero), the same IP address as before should be assigned to the controller.
  • If the rotary switch is set to 1-9, a pre-configured IP address is defined.
    • This IP address must be taken into account when trying to reconnect to the webpage using a web browser.
