Web-based Management 2:
System → Update

Valid from firmware release 2025.0 - for earlier firmware see Administration - Firmware update

On the Update WBM 2 page you can implement an update for the firmware or for an automation project on your device.

Note: Access to the specific pages in the WBM 2 depends on user roles and their rights - see WBM 2: Accessibility for details.

Firmware update

Note:

• Everything that is written here goes for updating to a newer firmware release or for downgrading to a former firmware release.
• When installing a pre-2025.0 firmware, the former Web‑based Management will be installed with it. For proceeding on that user interface, see WBM access and first steps.

Getting a firmware file

• Download the firmware file from the regarding product page on the Phoenix Contact website. In its Firmware section you find all firmware versions and hotfixes that are available for your PLCnext Control device.

Hint: In the right-side panel of this WBM 2 page you'll find a link which leads you directly to the product page for your device; if that panel has been collapsed, re-open it by means of the icon in the lower-right corner.

Firmware section links for the PLCnext Control devices

• AXC F 1252

Preparing for a firmware update

Security note 
To make sure that software or firmware files downloaded via Internet have not been corrupted or tampered, perform an integrity check of the downloaded files. You can find further information in Integrity check of downloaded files.

 To prepare for a firmware update, proceed as follows:

• Unzip the *.zip file to provide access to the *.raucb update file from the Web‑based Management.
• Only in case of installing a legacy firmware that contains Windows® executables: 
  Run the *.exe setup file and follow the instructions in the installation wizard; the *.raucb update file and files with device-specific information will be copied to the selected destination directory.

Executing a firmware update

• Enter the Web‑based Management 2 (see WBM2 introduction) and navigate to the System → Update page.
• In order to check for the firmware update to be successful later, note the currently installed firmware version which is displayed in the Version column of the Update list.

  

• In the table row showing the current firmware, click the Update button. 
  ↪ The Update Firmware dialog shows; the Status shows Idle, and the current and the fallback version of the firmware are mentioned.

  

   

• Make sure that the device can be stopped; to proceed, click the Prepare and Stop button in the lower-right corner.
  ↪ The device is prepared for an update and a running application stops; the Status changes to PreparedForUpdate (for details to that state machine see Updating).
  ↪ If you need to cancel the update process from here and get back to the idle state, click the Resume button at the bottom of the dialog.

  

• Click the Select file button, then navigate to the *.raucb file you prepared in the previous step.
  ↪ The selected firmware file name is displayed.
• Decide whether the Resume automatically after installation toogle switch should stay activated:
  • If activated, the device's operation will be resumed and installed applications will be started.
  • If deactivated, you can do other steps after the firmware installation and resume manually. 
• Click the Start Update button in the lower-right corner.
  ↪ The firmware is installed, displaying steps with a progress bar:
  • The software package is first transferred to the device and the proper transfer is evaluated; if successful, the pending version is displayed.
  • The signature is verified.
  • The fallback firmware image is copied to the rootfs file system.
  • The device is rebooting from the updated firmware.

    

• When the Startup dialog shows in the browser, wait for the device to restart.
• As soon as the "Lost connection to the device" warning is disappears, log in and navigate to the System → Update page. 
• To check the current and the fallback version of the firmware, proceed as follows:
  • In the table row showing the current firmware, click the Update button. 
    ↪ The Update Firmware dialog shows.
  • Check the current and the fallback version of the firmware.
  • Close the Update Firmware dialog by clicking the X icon in its upper-right corner.
