Post by wagokurt on CODESYS Visualization M License Fails to activate on Linux SL ^{CODESYS Forge talk (Post)}
I have successfully activated a CODESYS Control Performance M on a Linux IPC. When I try to activate the CODESYS Visualization M license it fails with this error. Any ideas? This is a WAGO 752-9401 FW4, running Debian 12.

This is what is on the device, is this correct? I did not see an option to install TargetVisu, is this needed?

In the device selection. Do not filter on Phoenix. Remove this filter and first add an Ethernet Adapter from CODESYS. To this Ethernet adapter add the Profinet Controller. After this you can filter on Phoenix devices in the "add device dialog".

i would be looking at what the case variable is doing then.. sounds like there might be a logic race going on

Hi @andreal, Were you able to adapt a codesys runtime to your linux based device? I am planning on the same lines. we want to develop a small controller of 64IOs for our application. We want to adapt codesys runtime on our Arm processor based embedded linux boards.

Hello, I am trying to save my settings as a recipe on the Raspberry. As target path I use /user/Documents Save: SaveRecipeAS, 'Recipes', 'Recipe' Load: ReadRecipe, 'Recipes', 'Recipe' However, no recipe is created. What could be the reason?

anyone else running into the same issue: perform a repair install on the runtime, that should fix it without affecting license.

Hello all, I cannot find anything connecting IEC-61499 to CODESYS. Considering the quality of the CODESYS IEC-61131-3 implementation and that IEC-61499 expands on it, literally including as integral part, why is there no mention of CODESYS and IEC-61499 anywhere on the internet?

No, you can´t. I have only tried different browsers on my PC and then on my HMI device. Unfortunately the device´s browsers did not support pdf file as I needed so I had to switch to *.txt.

..this is still not released therefore not available in the CODESYS Installer. This will come to 4.13.0.0 release but if needed preliminary might be possible on demand.

use a realtime capable target, not Control Win. Either a realtime patched Linux or Control RTE on Windows.

Wago have documented that v3.5 is supported on their 821x controllers but not their 820x ones. Is it possible to import a device description and get it to run?

Hi thanks once again, Yes it supports because using python scripting I'm able to send data from the rasberry raspberry and receive it on my pc and vice versa (Image attached). But when using the CoDeSyS I just got red flags. Any light on this problem?

Hello. It is interesting that almost everyone has faced this problem. Run the program as shown in the attached photo. Give True to the Enable input and change the status of the drive to on and off with Servo-On

[Update]. My issue's solved, I applied the resistors in Pull-down configuration on each digital input. In thus configuration never happened "floating or delaying" acquisition on SoftPLC/Arduino Board.

Update: it seems that the license is detected by CODESYS on my computer but not detected by the runtime on my device. I'm using Codesys control for raspberry pi in the latest version 4.11.0.0 Is there something to do to correct this ?

Thanks @eschwellinger! So my settings look like this on CODESYSControl_User.cfg: [CmpWebServerHandlerV3] AllowFileTransferServices=1 CallVisuServicesDirectly=0 Sadly, is still asking for user and password as soon webvisu is loaded... Any clue? Many thanks!

Post by mondinmr on Frustration-Fueled Feedback on Project File Management and Git Integration ^{CODESYS Forge talk (Post)}
In reality, other vendors are already moving towards integration with VS Code. B&R, for example, is likely the only one that could truly challenge Codesys in the market: they’ve overhauled their once-archaic environment (previously lacking ST OOP) and are now catching up significantly with Automation Studio Code, offering modern programming capabilities and native support for tools like Git and GitHub Copilot. The other big names in the market, frankly, are still light years behind. For smaller projects, typically handled by “wire strippers” (with all due respect!), a classic environment might be just fine. But once you’re dealing with thousands or even millions of lines of code—possibly organized in an OOP paradigm, spanning large teams, integrating third-party libraries, requiring version control, and performing comprehensive tests—a lightweight, responsive editor supercharged with AI-based features becomes essential. The real strength of something like VS Code lies in its vast ecosystem of extensions and integrations: from advanced Git support to automated build/test pipelines, and even AI-assisted autocompletion that already makes software development much more agile and productive. I understand that a PLC project involves more than just ST code (task setup, fieldbus configuration, libraries, etc.). However, there’s no technical reason not to at least provide ST files in a pure text format, making version control and collaboration far easier. B&R has clearly adopted this approach; I hope Codesys will accelerate its own efforts to offer a native, text-based integration and modern development tooling. Once you go beyond a certain level of complexity—dozens of configurations, OOP hierarchies, and distributed teams—you really do need “engineer-level” software tools, not just solutions targeting “wire strippers.” For large-scale automation projects, a more open and flexible approach is the only way to avoid chronic frustration. Let me emphasize that I truly love Codesys and consider the work done so far to be brilliant—I’d be sorry to see it overshadowed by others moving faster in this direction.
