Hello,
i have a very old AXL F 2152, HW2 FW 1.0.0.250. The webpage does not provide any options to update the firmware. What tools or instructions does PxC provide to be able to update the unit firmware.
Hi Gmathisz,
In early firmware’s like that, updates must be done via the command line. You can use protocols like FTP to move the .raucb update file to the controller and SSH to remote into the command line.
People often use WinSCP for FTP and Putty for SSH, but my favorite tool is MobaXterm which can do both.
Once you FTP the update file onto the controller you must create a root user then issue the update command with:
‚sudo update-axcf2152‘
Here is some information about connecting to the controller via SSH and using FTP:Connecting to the controller
With the above instructions i managed to update to the controller to 2024.0.8 LTS. A couple of notes in case it might help somebody in the same situation:
1. After establishing connection to the controller i copied with WinSCP the image to /opt/plcnext/ folder
2. Trough SSH from command line i ran the sudo command shown by gshields.
3. In order to get to the latest LTS (2024.0.8 LTS) i had to update in the following order:
* 2021.0.5 LTS - 2021.0.5.35585
* 2022.0.8 LTS - 2022.0.8.161
* 2024.0.8 LTS - 2024.0.8.183 (currently last LTS version)
That’s good to know. Anyone that needs to do something similar can also refer to the process described in the PLCnext Technology Info Center, which is similar to what you have described:
Operating system The PLCnext Technology control platform is based on a Linux® operating system with the OSADL real-time patch. Linux® is a highly reliable, open source operating system suitable for applications that require a high stability. A wide range of open source software is available for the Linux® operating system, which is supported by a large community of users and developers.
