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.

Post by snhatton on OpC UA server on Raspberry Pi 64 SL runtime ^{CODESYS Forge talk (Post)}
Good afternoon, After changing the security settings to: CommunicationPolicy: POLICY_BASICSHA256SHA256 CommunicationMode: ALL Activation: Activated UserAuthentication: ENABLED Then generate a new certificate on the device for the OPC-UA server from Security Agent->Device->OPC UA Server. Restart the runtime using tools->Update Raspberry Pi->Stop->Start for the changes to take effect. It may take a minute for the runtime to start. Initiate the connection from the UA server side. You should see a pop-up asking you to trust the certificate. Click on the button 'Trust Server Certificate'. Next, you should see a certificate in the quarantined folder of the security agent in CODESYS. Click and drag this from quarantined to trusted and then try connecting from UA expert to the device. These steps worked for me and my setup and I hope they can help you!

Post by sean-barton on Function block method default arguments ^{CODESYS Forge talk (Post)}
I have default arguments specified for function block methods but when calling a method, an error is produced requiring me to supply all the arguments despite there being default values. According to the online documentation, under section "Calling a Method" and subsection "argument passing" of the following link: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_obj_method.html "Passing an argument for an input ... can be omitted ... for which a default or initial value was specified in the declaration..." I have found this to be the case for all Codesys IDEs I've used, 3.5.11, 3.5.16, 3.5.17, 3.5.19. Am I missing something?

Post by royw on Profinet library for C# ^{CODESYS Forge talk (Post)}
Hi, I don't know if I'm in the right place or if it's even possible... I'm looking for a way to address a Profinet device with Record Read and Write from my own PC. I actually only need very few commands to configure our device. This means setting the MAC address and a serial number. We would like to do this from a C# program. Now we are looking for a library or something similar. Since you can do it from Codesys, I thought there might be a DLL or something similar that you could use for this. As I said, we don't want real-time queries of the cyclic data but only record read/write. Does anyone have any helpful hint? Thanks in advance
