hello edwin i have did the same and i could connect the opc-ua server but i dont see anything in the resources tree, in the application i linked my variables to the symbol configuration but i dont see that in the uaexpert. if i use the same application with a non linux system i can get those variables values and see the complete tree structure. What could be the problem ?

Post by mini-developer on Precompilation Error NBS.UDP_Peer ^{CODESYS Forge talk (Post)}
Hello, I use the Library NBS from "caa net base services". After opening the Project i get 19 errors from the message window "Precompilation", most of them because it doesn't recognise a component of the FB "NBS.UD_Peer". (see photo) After compiling the Project at least 2 times, there are no errors. Is there a reason and solution for this behavior? Is there a problem with resolving the library? Thanks for any clue

Post by taqamert on IFM-Sensor ADC READ ^{CODESYS Forge talk (Post)}
I have a pressure sensor that measures 0-600 bar and outputs a 0-5V signal, but my PLC reads analog inputs in the 0-10V range and displays a value of 1024 when 10V is applied. In this case, when the sensor outputs 5V at 600 bar, the PLC shows a value of 512. My working range is 0-350 bar, which means the PLC only uses 298 bits in this range, significantly reducing the resolution. What can I do to achieve better resolution within the 0-350 bar range?

Post by szotyi on Array of Program ^{CODESYS Forge talk (Post)}
Hi! What is the proper and the easiest way to call programs through looping of array of programs, or pointer of program? instead of calling the programs one by one: prog1(inputX: 11); prog2(inputY: 12); prog3(inputZ: 13); similar like: VAR programsToCall : ARRAY [1..3] OF PROGRAM; END_VAR programsToCall[1] := prog1(inputX: 11); programsToCall[2] := prog2(inputY: 12); programsToCall[3] := prog3(inputZ: 13); FOR i := 1 TO 3 DO programsToCall[i] (); END_FOR Thanks.

Post by egau on Mutate Hash table value ^{CODESYS Forge talk (Post)}
Hi, using the ElementCollections Library, why isn't it possible to mutate a value found within a HashTable? From what I understand, the only way to change a value would be to use the RemoveByKey(), followed by AddKeyValuePair(). My goal is to use a Data Structure that works like a Dictionary in Python. The HashTable seems to come close to this, except that the values themselves seem to be immutable... In python, we can mutate a dict easily (see attached picture).

Post by paulpotat on cm4 runtime problem ^{CODESYS Forge talk (Post)}
It looks like it works with 4.13.0.0 indeed. However when installing the runtime, it's not possible to select the multicore option (see attachment). But once the 4.13.0.0 runtime is installed, the logs seems to indicate that the runtime is running in multicore mode. Looking at "htop" output, it seems like it actually is running on multiple CPU. This is very misleading, is it normal or is this a bug ? Thank you for your answer @eschwellinger, BR

Hello, the option to update Rasberry Pi from under the Tools menu is missing in my installation. Currently I have the build 3.15.19.50, along with the Pi package 4.11.0.0. But the same problem is observed even with the latest build and Pi packages. I have tried clean install with both the versions but cannot solve the issue. I never faced this on Windows 10, but now the new PCs are with Windows 11 - this is the only difference. How can I solve this problem?

Post by timvh on Unable to Connect to Modbus RTU Device ^{CODESYS Forge talk (Post)}
If your Control Win is the Modbus "Master" then your configuration should be something like: Modbus_COM (Serial port) - Modbus Master (this is the Control Win SoftPLC actively setting up the communication) - Modbus Slave (this is then your WAGO 750-315) You need to add channels to the Modbus Slave configuration to inform the master which variables to read/write from the Wago module. The way you configured it now, the Control Win is also a slave. PS, don't forget to put the PLC (Control Win) in Run.

Hi mate, With this snippet i was able to see the lastusage variable count, but it would not iterate between clients? i was only able to access the data of the target visu. it threw an error with the array of pointers stating it was not able to convert etc. also when i tried it with the while loop it created an endless loop and crashed the program. any ideas? Thankyou

Post by alex-at-xana on EThercat Dynamic configuration ^{CODESYS Forge talk (Post)}
Ah - forgot another question as it may be related to the PLL problem: I am executing a 4ms cycle. I do not call (from what I know) the Ethercat_MAster periodically in my program. The bus cycle task is set to the Ethercat task. I would assume that the master should send 250 frames per second. Yet, the status of the master says it transmits 500 frames per second which would indicate that the master is called twice. Any ideas there?

Post by dkugler on TargetVisu Freezing ^{CODESYS Forge talk (Post)}
The only weird situation i remeber with particular or complete frozen target visu was after the rtc clock was fallen or set back to the past. It looked like after running a while the alarm history database crashed during writing entries at a date lot of years in the past. After setting the rtc clock to actual date/time and deleting the alarm db every thing worked fine. I don't know, if this is/was a problem of our PLC hardware/firmware? Maybe check date/time at your system?

Post by jinlee on Camera RTSP Feed ^{CODESYS Forge talk (Post)}
Hi, I followed your guidance and used go2rtc. There is a link generated from go2rtc I can copy into the web browser element in the visualisation. It somehow only appear within the software when it is running, but not on the webvisu. I want to display the camera feed onto the webvisu. My camera is reolink 810a which supports IP protocol. My project is pretty simple, just a web browser element with assigned URL.

Post by timvh on Stack overflow with really simple function ^{CODESYS Forge talk (Post)}
You have declared the function block in a function and call the instance also from a function. This is not correct, because a function is initialised with every call. The http client function block should be declared as Global Variable if you want to cal it from a Function, but probably it is better to declare it in a Program and also call the instance of the http function block from the same Program.... The variables of a Program are not initialised with each call.

Post by timvh on Communication between applications on same device/controller/runtime (Win RTE 3.5.20.20) ^{CODESYS Forge talk (Post)}
The RTE will take the RTE license. The HMI will take the HMI license. For the Application Based Licenses, the Runtime will take the smallest which is required. So if you have an application running EtherCAT and no visualization, only the Control with support for EtherCAT is used. If you have another runtime which requires the visualization, it will take the smallest Control license which is required and available + the smallest visualization license which is required.

Post by totorovic on Hard shutdown: no code on device after power on ^{CODESYS Forge talk (Post)}
However, if faulty EtherCAT cables were the issue, why wouldn't the error occur during normal operation? Why would bad cables only cause problems during a hard shutdown? I don't have the answer to this question. One last question: When you encountered this behavior, did you see a similar error in your logs? i.e, an "AccessViolation" exception in the EtherCAT Task Yes. It was the exeption you can see in attached file.

I'd like to know if it is possible to have the "Name" field, in the recipe definition, language dependent. Something like to have the possibility to put there a string ID that will be add to the GlobalTextList. In this way it can be translated and when showed in a Visualization screen its value depend on the current language. Thanks.

wow und wie das Problem gelöst wurde für den Nächsten Anfänger?! Naja egal. Das mit dem Farbwechsel ist bei mir kein Problem, ich frage mich nur, warum beim Farbverlauf immer als Alarmfarbe in der Mitte weiß genutzt wird?! Meine Buttons sind alle dunkel und haben weiße Schrift, die kann man dann natürlich gar nicht mehr lesen. Kann man das noch anpassen? Also, dass beim "Alarmzustand" der Farbwechsel nicht als zentrale Farbe weiß hat? Die Farbe die ich auswählen kann ist immer die außen liegende Farbe -.-

I ended up figuring it out It wasn't in my code. It kept taking me to 2 of my visualizations but it wasn't going to anything specific. Figured out it was some arrows that I had made to buttons for a mouse click to go to the other visualizations. I removed the text in the assign box but didn't remove the action "change shown Visualization from the list. If I deleted the images all together, the error went away. That's how I thought to go look at that.

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.
