I updated the Codesys version from “V3.5 SP20” to “V3.5 SP20 Patch1” and that solved the problem.

Post by mondinmr on Frustration-Fueled Feedback on Project File Management and Git Integration ^{CODESYS Forge talk (Post)}
Good day, I’m writing this message out of frustration regarding the current way project files are saved as encrypted XML and single-file format in CODESYS. I find this approach to be quite tedious for several reasons: Limited Access to Structured Text: Not being able to access Structured Text (ST) externally makes it impossible to work with alternative editors like VSCode. Tools like VSCode are incredibly responsive and feature advanced systems such as GitHub Copilot, which would be a real game-changer when working with ST IEC. While CODESYS works well for small code snippets or debugging, when the codebase grows, switching to VSCode to boost productivity becomes essential, and copy-pasting between environments is a cumbersome workaround. Poor Integration with Git: This file format also makes it very difficult to integrate effectively with Git. I have tested the internal demo, but for advanced merges, it is unusable. Without properly formatted plain text, it’s impossible to leverage the vast ecosystem of external tools around Git that allow smooth merges in heterogeneous teams. File Corruption on Network Drives: I often work from multiple locations with shared network drives. When the development environment saves a file and something goes wrong midway (which can occasionally happen when using VPNs and network drives), the entire project becomes irrecoverable. There’s no way to cancel the save process, and the development environment freezes. This has happened to me at least four times over the past two weeks, and one of those incidents cost me an entire day of work. All of this is particularly disappointing because I truly believe that the libraries, runtime, and overall work done by CODESYS are exceptional. I find it fantastic that there is a platform allowing development of PLCs and control systems using OOP, which is a huge advantage in modern control engineering. I apologize for the rant, but this issue has been extremely frustrating. Best regards.

Post by jarnok on How to know if output if function block is used ^{CODESYS Forge talk (Post)}
Hi, Is it possible to know of an output of a function block is used? I've found there is a way to find unused inputs of a fb, through the attribute: is_connected. But I'm wondering if the same can be done for an output. Thanks in advance!

Do someone have any information on this topic ? We tried several different CM4 boards without success, and we cannot install the licenses we bought anymore... Isn't CodeSys supposed to support CM4 Raspberry pi ?

Post by ellocco on Kann mich nicht am Gerät anmelden ^{CODESYS Forge talk (Post)}
Ich benutze das virtuelle Gerät "CODESYS Control Win V3 x64" und schaffe es nicht, mich am Gerät anzumelden, CODESYS v3.41p18 meldet: "Ungültige Benutzerauthentifizierung auf dem Gerät". Gibt es die Möglichkeit vorhandene Benutzer zu löschen? Ich habe das Gerät / die PLC bereits über das externe Programm: "CODESYS Control Win V3 x64" gestartet, beendet und erneut gestartet. Aber es hilft nichts, leider ist die Sicherheitsverwaltung ausgegraut und ich weis nicht, wie ich die freigeschalten kann.

the interpolation block does not start from the absolute value. It returns to zero even when writing to dLastWayPosX , Y , Z.

I'm having trouble getting started with the SysFile library. I tried copying and running the code found here: https://forge.codesys.com/forge/talk/Engineering/thread/f17c3d0e64/ Every time I try to run the file handle pointer returns: 16#FFFFFFFFFFFFFFFF <dereference of="" invalid="" pointer=""></dereference> I can see the file when I look in the Device -> Files window Any idea what I'm doing wrong?

Post by bzzz on Connect WS2812B Light Strip to CodeSys via RasPi ^{CODESYS Forge talk (Post)}
Hey guys, I have a RasPi and can control my WS2812B (addressable light strip) via Python. The lightstrip is this one: https://core-electronics.com.au/1m-rgb-led-strip-ws2812b-144-per-meter-white-strip-weatherproof.html What I would like to do is to control it directly via CodeSys through the plc on my RasPi. I know I can run a python script on CodeSys, but I'd like to avoid doing that. Is it possible, and how do I do it? Is there a library that does this?

@fscardovi You might check the location of your CODESYS.exe.
