Post by snguyen on Atomic and Shared memory? ^{CODESYS Forge talk (Post)}
Hi, I've read that you can perform Atomic instructions like AtomicReadLInt on variables. However, I'd like to know if this uses stdatomic internally. My main question is : Is it possible to share atomic types in shared memory with CodeSys. If so, what types should they be declared as? If not, are the atomic functions lock-free or does it use a mutex?

Post by manuknecht on FileDialog - OnDialogClosed not called anymore ^{CODESYS Forge talk (Post)}
I had similar issues with the OnDialogClosed not being called. I realized that this behaviour is resolved, when the according visualization object on which the input configuration is set is moved to the foreground. Somehow, the object has to be one of the lowest elements in the Element List (i.e. in the foreground) for it to work.

Hi All, I'm using git (1.4.0.0) in CoDeSys (Rexroth ctrlX 3.4 / CoDeSys 3.5.20.30). Every time I click on a modified file in the "Git Status & Staging" view I get the message out of attached file. I do not find any hint: Does anybody have an idea what the cause is? Thanks in advance.

Post by nano on Creating, using an external Function. ^{CODESYS Forge talk (Post)}
the Answer is easy, you don't reapecting the codesys-behaviour and pre-request on a dll/so like you like to create. codesys won't load it about the fact that the dll isn't registered in codesys. check this page for more informations: https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_extension_extension_sdk.html

Post by chanmina on Engineering IDE from linux? ^{CODESYS Forge talk (Post)}
For a long time now, I have used VirtualBox on a Linux Mint host to run the Codesys IDE without any problems. Every day, I put it to good use, and it never fails. Wine is not something to be trifled with. Probably not worth the effort. For Linux PLC developers, Codesys Go might be a game-changer. Very excited to give it a try.

I have on my Pi successfully deployed an application to which with composer AC_Datalog is added. It starts logging automatically. I want a Visualization with a start/stop button controlling the logging. That must be easy. How do I do that?

I'm trying to open the VisuDialogs.Numpad dialog to enter a new temperature setpoint on one of my VISU screens. For some reason, the numpad dialog does not appear as an option in the Open Dialog dropdown in my input configuration. I'm very new to CODESYS, so sorry if this is a simple fix/known item XD.

Post by wagokurt on TargetVisu option missing in IDE ^{CODESYS Forge talk (Post)}
I have installed both the Codesys Control for Linux SL 4.16.0.0 and Target Visu for Linux 4.16.0.0 packages in Codesys 3.5 SP21 Patch2. When I try to add a target visu, it is missing. I have spent hours on this and tried different machines, all behave the same way. Is this a bug?

Post by morecoffee on Control for Raspberry Pi 4.17 ^{CODESYS Forge talk (Post)}
I am currently having the issue that Codesyscontrol only runs for 10 seconds on my Raspberry Pi 4. I believe the problem is because the MAC address range is of the Raspberry is 88:A2:9E:XX:XX:XX. When will Codesys Control For Raspberry Pi 4.17.0.0 be released to fix this issue?

Post by wagokurt on CODESYS Visualization M License Fails to activate on Linux SL ^{CODESYS Forge talk (Post)}
The fix for this is when you install the control SL license, there is a checkbox for the Visu S license option. You must click this option. The Visu M is technically an upgrade to the Visu S, if this is license is not installed them the Visu M will fail as shown above. Thanks JoJo for the solution!

Post by timvh on update data/tim ^{CODESYS Forge talk (Post)}
Change the actual time of your PLC. How to do this sometimes depends on the PLC you use. Please contact the vendor of the PLC to get this information. Or see the following example for using CODESYS date and time functions: https://forge.codesys.com/prj/codesys-example/date-and-time/home/Home/

Post by jcarter on Webvisu Combined Authentication ^{CODESYS Forge talk (Post)}
Is there a way to have both a Public No Login Screens with Screens that do require login and File Transfer? My Idea is to have the default page be View Only with a Login Button in the Corner and then Once Logged In you can change settings and download files depending on your user group.

Yes, you are right. I think the help is pretty clear: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_library_development.html It helps you to find errors in the source code of your library if you want to create a library which is using pointers and you want to use your library on 32 and/or 64 bit platforms.

Enabling Anonymous Login 1. Navigate to 'Device' > 'Communication Settings' > 'Device'. 2. Next, click on 'Change Runtime Security Policy'. 3. In the new window, find and check the box for 'Allow anonymous login'. After completing these steps, you should be able to communicate with the OPC UA server.

Post by mondinmr on What happened to Python? ^{CODESYS Forge talk (Post)}
What happened to Python? I’ve just installed version 3.5.21.3 of the CODESYS development environment. I’m coming from 3.5.19.5. What happened to Python scripting! We rely heavily on it for the automatic generation of thousands of lines of code! It seems absurd to me that such an important feature has been removed!
