Post by timvh on Specify Input Configuration "OnDialogClosed" Action to only react to certain Dialogs ^{CODESYS Forge talk (Post)}
What maybe helps is the Visu Dialog ST demo project: https://store.codesys.com/en/visu-dialog-st.html This has an application IECOpenDialog where dialogs are opened using the VU.FbOpenDialogExtended function blocks. The fbOpenConfigurationDialog call has a reference (interface) to the "close listener" FB of which it's method is automatically called when the dialog is closed. This way you can create specific function blocks for each dialog when it is closed and do what you want with the data that might have been changed.

Post by tehthoams on Library Search not working ^{CODESYS Forge talk (Post)}
Hello All! Having a strange issue. When adding a library, I'm unable to search. Each time a window pops up 'creating the search index' and then has 0 results. I have the same behavior when using the library repository and pressing the 'Find' button. I wonder if there is a way to reset or fix this issue? It is making it very difficult to search and find proper libraries to add to my project. Much appreciated.

Hello @eschwellinger, Why not using one of those 2 folders: C:\ProgramData\CODESYS C:\Users\Public\Documents\CODESYS The main reason is depending on the company and the user right, the end user may not have the access to use those folders. Also having a non version dependent folder may help if the end user uninstall a previous version and forgot all its sample project where in this previous version installation. Thanks.

I started a project in codesys for a WAGO 750-8212 PLC and I am working on getting online with the controller. I can log in to the controller and I can see and control all of the fieldbus couplers that I have. I am unable to get the internal bus working. It just says that the bus is not running and when I scan or devices nothing shows up. Am I missing something important in my device tree?

Hi, sorry I can´t help you with your issue, but I hope you can give me a hint on getting GUID for other objects than POUs. Your code states "Guid("6f9dac99-8de1-4efc-8465-68ac443b7d08")". We can I find the GUID / ObjectIds`? I wasn´t able to get details about the GUID of DataTypes (STRUCT/ENUM,..)m, Functions (FUN), GLOBALS and TYPES. I want to create markdown of all available project elements. Thanks for your help

Hi micik, I am not sure I am using well the code, because I checked the directory and there is no retains.ret file. Now I deleted the code from my project and the values are still works as persistant variables after ssh reboot it seems to me they retain as their previous value. So I am a bit confused, maybe 4.12.0.0 Raspberry Pi SL solved the persitent variable problem...

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.

I succeed to change the device to PI_SL but still the same problem of the I2C device switching between running and not running. the only difference with your project is that yo use I2C_master device version 4.7.0 and i 4.7.13, for GPIO i also use the 4.7.13 version and you the 4.7.0. Can you send me the older version of the Raspberry PI pheripals library, because i cannot choose lower version then 4.7.10 for the GPIO and I2C_master device

Hello, I'm using Codesys 3.5.20.0 version and I noticed that even with the most basic standard project create, there are error messages like shown in the acttached picture. The similar questions are already asked here on the CODESYS Forge Talk, but remained unanswered. Exact screenshot is attached, but essentially I would like to know which component in the Codesys has CmpID = 0x00000019 and what this Timeout means?

Post by timvh on Codesys Runtime Devie Password ^{CODESYS Forge talk (Post)}
This has been moved because of security reasons. But it depends on how you start CODESYS where the project files are located (at least for Control Win from SP20). 1) If you start it through the sys tray icon, you start it as a service and the files will be located in: C:\Windows*System32\config\systemprofile\AppData\Roaming\CODESYS... (or C:\Windows*SysWOW64**\config...) 2) If you start it as a user, e.g. with a shortcut to the runtime, you can find it in: C:\Users\<your user="" name="">\AppData\Roaming\CODESYS...</your>

Hello, I have developed a Python script that I run to import XML files into my project. For this, I use the Python function import_xml(). Everything was working fine when I was using Codesys platform plugins version 2.6.1.2320, but since I upgraded to versions 2.7 and even 2.8, some files are no longer imported correctly. After some research, I identified that all the files containing variables of the type "POINTER TO" are affected. I have attached a screenshot of the error I am encountering. Do you know about this bug? Do you plan to fix it?

I want to run the following command by linking it to the A-Axis: G01 A45.0 Which TRAFO should I use to do this? SMC_TRAFO_5Axes and SMC_TRAFO_GantryCutter3 function blocks did not work! For example, when SMC_TRAFO_5Axes is used, parameters B and C can be resolved by the transformer. However, parameter A cannot be resolved. Only SMC_Interpolator displays the value of parameter A in the SMC_Interpolator => piSetPosition.dA output. Should I drive this axis with SoftMotion commands (MC_MoveAbsolute etc.)?
