Post by milosfejgl on Codesys Licenses - How to reload them after updating the Raspberry Pi OS ^{CODESYS Forge talk (Post)}
We use several control units running on Raspberry Pi, programmed using Codesys software, with multiple licenses stored as soft containers. We are planning to update the SD card image of the Raspberry Pi to a newer OS version. However, we are concerned that this process might result in the loss of our soft container licenses. Is there a way to temporarily deactivate the license so that it can be reactivated on the updated system? Alternatively, what would be the best method to preserve the licenses during the update? Thank you in advance for any responses!

Post by agentcousto on [Bug report] Issue with Importing XML Files Containing "POINTER TO" Variables in Codesys Platform Plugins Versions 2.7 and 2.8 ^{CODESYS Forge talk (Post)}
Hello, I have developed a Python script that I run to import XML files into my project. For this, I use the Python function import_xml(). Everything was working fine when I was using Codesys platform plugins version 2.6.1.2320, but since I upgraded to versions 2.7 and even 2.8, some files are no longer imported correctly. After some research, I identified that all the files containing variables of the type "POINTER TO" are affected. I have attached a screenshot of the error I am encountering. Do you know about this bug? Do you plan to fix it?

Post by elsmart on How to create custom visualisation components (widgets)? ^{CODESYS Forge talk (Post)}
Hello I'm currently working on a project where I need to implement visualisation in Codesys on Raspberry Pi via web browser. I'm uing Codesys IDE V. 3.5 and I was able to successfully run my program and visualisation using generic elements provided by Codesys on Raspberry Pi Compute Module 4. However I am dissatisifed by the limiations and looks of generic elements. I would like to create my own components for this specific task (like cyclic buffer with messege boxes or matrix of data structures). How do people develop their own visualisation components in Codesys and how to implement them in a project?
