Post by voffi on projects.open not working for file based storage project ^{CODESYS Forge talk (Post)}
Hello! Opening a project from a python script given at the CODESYS command line does not work for me with a file based storage project. Example: Running projects.open("test.project", primary = True) works but converting the project to a file based storage project and then give the folder name as an argument to project.open Running projects.open("test.fbsproj", primary = True) does not work. We decided to work with file based storage for the project. Is there a scripting API for file-based storage to e.g. convert it while running the script back or how to open file based storage project with projects.open? Thank you! voffi

Post by pernockham on Control for linux SL, 4.14.0.0 -> 4.15.0.0 breaks web page access. URL requires authentication ^{CODESYS Forge talk (Post)}
I have a problem which I have identified with a device-update from 4.14.0.0 to (4.15.0.0-4.17.0.0) where the newer versions will stop any local access to the internal web page with the browser responding "The requested URL requires authentication". Setting the device back to 4.14.0.0. the web page will respond. Access to web page through Automation server is possible also for the newer version, but not "local" access. Runtime (Codesys control for linux SL) is on 4.17.0.0. I have tried to manipulate settings for 'Access-Control-Allow-Origin' '*' always; through nginx (normally a proxy_pass to localhost:8080). Also tested bypassing nginx by accessing 8080 directly with the same result.

Post by arjunk on How to correctly create a device descriptor (.devdesc.xml) for a custom Linux ARM64 PLC in CODESYS 3.5.21.20? ^{CODESYS Forge talk (Post)}
I’m trying to integrate a custom PLC into CODESYS so that it appears under the Device section. From what I understand, this requires a .devdesc.xml device descriptor file. I attempted to create the XML manually, but whenever I try to install it in order to generate a .package file, CODESYS crashes. CODESYS version: 3.5.21.20 Target PLC: Linux ARM64–based My questions are: Is there an official or easier way to generate a valid .devdesc.xml file for a custom PLC? Are there tools, templates, or examples that can help ensure the XML is structured correctly and won’t cause crashes? For Linux ARM64 targets specifically, is there a recommended starting point (e.g., modifying an existing device descriptor)? Any guidance or best practices for creating and packaging custom device descriptors would be greatly appreciated.
