First of all you need to enable "Use unicodestrings" in the Visualization Manager. This function returns a pointer to a WSTRING (not STRING). To get this wstring value, do something like this: VAR myWstringVariable : WSTRING(255); END_VAR myWstringVariable := myResult^; // this is dereferencing the pointer to the WSTRING.

Post by paulpotat on Can't open license manager with raspberry CM4 ^{CODESYS Forge talk (Post)}
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 paulpotat on Can't open license manager with raspberry CM4 ^{CODESYS Forge talk (Post)}
Update : The solution I mentionned in a previous post does not always work. Some Raspberry Pi CM4 still won't create the license container. I will open a support ticket.

Also. Every third (or so) attempt to login/compile is unsuccessful with the error prompt "one or more errors occurred", however there is no information available on what this error might be. If I remove the PersistenceManager-module, these problems are not present.

..strange just switching of this device without graceful Linux OS shutdown? Reset orgin on the device tree and a new download of the application will bring it up and running again but sure then the persistent data are for sure lost.

Post by gerdkoch on Dynamic I/Os Mapping ^{CODESYS Forge talk (Post)}
Hi, I assume that you have a Pfc200 G2 or something and work with the original WAGO runtime. Then I would recommend the WagoSysDynamicIoMapping. Here in the example projects there is a PDF file for the library: https://downloadcenter.wago.com/learning-material/details/ll0w3pmdunzvem83g1 There is a global functional component in a GVL of the library. I think it's called DynKbusIoManager or something. The active terminals are registered there. Then there are filter Fb's for e.g. the first clamp with a specific article number. Everything is in the PDF.

Post by john-martin on Control SL Extension Package doubts ^{CODESYS Forge talk (Post)}
Hello everybody, I'm trying to understand the SL control extension package, more specifically, the external IODriver example, because C integration is very easy and I just made my first C component successfully. Ther External IODriver has no documentation and it's not clear how to proceed. Furthermore, there is no information on how to modify the device descriptor, which is necessary to import the device into the Codesys repository. Any advice ? Thank you in advance and best regards.

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 jeroenaero on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
Finnaly i get it working. There was a line in the file that set the ADS1015 chip in /boot/firmware/config.txt which i removed and after that the ADS1115 has a green turning circle and i got values. i created a new component so it fits our ADS1015. see screenshot. It works also with Codesys Control for Raspberry Pi 64 SL after adding the ULINT_TO_UDINT conversion in the library. i think the chip was all the time in use by the Raspberry pi itself. Thanks for your help!

Post by ewi04 on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
Hallo, I have a strange problem with the recipe manager. ISSUE: When using RecipeManCommands not all values are loaded correctly. Saving a recipe with CreateRecipe(), ReadAndSaveRecipe() or ReadAndSaveRecipeAs() works without any problems. BUT: LoadRecipe(), WriteRecipe() or LoadFromAndWriteRecipe() do not load the data correctly. It is Interesting that we have a different error pattern with LoadRecipe() than with WriteRecipe() or LoadFromAndWriteRecipe(). LoadRecipe() does not load all data and WriteRecipe() or LoadFromAndWriteRecipe() overwrites some data or assigns it incorrectly. And it is also strange that LoadRecipe() writes the values to the PLC. Normally it doesn’t do it. It makes no difference whether the memory type is textual or binary. I have an object consisting of STRUCTs which is inserted in the recipe definition. Environment: Codesys V3.5 SP19 Patch 4 (64Bit), Recipe Management 4.2.0.0 *Add a project (reduced to the problem)

Post by fdmartello on Unable to compare projects containing alarm manager 4.5.0.0 ^{CODESYS Forge talk (Post)}
Hello. In Codesys version 3.5.19.50 when comparing two projects that have an "Alarm Configuration" obj from the Alarm Manager library vers. 4.5.0.0 the attached error pops up. This originally happened with two projects that I converted from vers. 3.5.17.30 so, thinking it was some conversion issue, I created two clean projects directly in 3.5.19.50 using the Standard Project template and only added the Alarm Configuration objects in them. The result is the same and the only way I found that allowed me to compare them is by deleting the incriminated object in one of the two projects. Has anyone else encountered this issue? Best regards

Post by rcanfield on Code Coverage and Test Manager ^{CODESYS Forge talk (Post)}
I am exploring the possibility of measuring test coverage using the Test Manager and Profiler tools. It appears there are some significant limitations. Has anyone been successful trying to use these tools? Here are my observed limitations. Am I misunderstanding anything? * Profiler only works for one "run cycle". Even warm resets will clear the coverage calculations. Thus, all tests would have to manually reset values when complete to prevent contamination to other tests. * It is not possible to see which statements were/weren't executed. One would have to use the flow control tool which cannot be used in conjunction with the Profiler, and must be viewed in realtime. * The profiler control cannot be automated and therefore must be executed through a manual procedure. Thank you!

Post by sangeetnenwani on Test Driver Availability in CODESYS 64-bit and Test Manager 5.1.0.0 ^{CODESYS Forge talk (Post)}
I’m operating with CODESYS in a 64-bit configuration and the Test Manager at version 5.1.0.0, where I’m attempting to use project scripts from an earlier version. These scripts call for certain test drivers that are not present in my installation. It’s unclear whether the absence is due to the 64-bit system, an update in the test drivers, or if I need to enable or install additional elements. For instance, the loadproject(Codesys.Base) command is missing, but loadproject(testmanager.project) is available. The FileIO command for CODESYS isn’t accessible, yet the testmanager’s driver for it exists, as does the execuptscript command.

Post by elektron785 on Dongle von Linux-Modul (ARM64) nicht erkannt ^{CODESYS Forge talk (Post)}
Hallo zusammen, ich habe Lizenzen für CoDeSys gekauft und auf einem Dongle installiert, in der Hoffnung, dass ich diese mit einem Verdin-Modul von Toradex verwenden kann. Leider wird mir aber im Lizenz-Manager angezeigt, dass der Dongle nicht gesteckt ist. Ich habe bereits beide USB-Ports versucht, aber die Fehlermeldung bleibt gleich. Ist das überhaupt die richtige Vorgehensweise über den Lizenz-Manager oder gibt es da noch eine andere Möglichkeit? Ich gehe mal davon aus, dass die Lizenz nicht automatisch erkannt und verwendet wird? Wie im angehängten Bild "usb" zu sehen ist, wird der Dongle auch als solcher erkannt.
