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 atone on Set DeviceID of an IO-Link Sensor at Runtime ^{CODESYS Forge talk (Post)}
Answering to myself: is not possible according to the IFM support, this possibility has not been taken into account, although the interfaces and FBs in Codesys would apparently support it. So I ended up having to deactivate the sensor validation and the backup & restore functionality in the master and implement it in the PLC myself.

We just had this problem today when our IT updated a group policy. You need to go to Local Group Policy Editor > Local Computer Policy > Computer Configuration > Windows Settings> Security Settings > Local Policies > Security Options. Set "System Cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing" to DISABLED

Hallo Community Bei mir dauert das erzeugen das Codes bzw. das Einloggen extrem lange teilweise mehrere Minuten. Zuvor alles Bereinigen bringt auch nichts. Auch wenn ich keine Änderung am Programm vornehme und mich nur aus und wieder einlogge. Hat jemand eine Idee woran das liegen könnte?

Post by andrewb on Codesys Visu Update Frame Parameters No Dialog Appears to update ^{CODESYS Forge talk (Post)}
I'm also seeing this issue, my instances of the frame will date but not for new parameters that I add to it. Has anyone seen a fix or a way to force the parameter update other than recreating all the frame instances?

Post by davidking on Error, visualisation property handling, VISU_USEPROPERTYINFO ^{CODESYS Forge talk (Post)}
Solution: Disable VISU_USEPROPERTYINFO define Go to Project → Options (or Project → Properties, depending on your CODESYS version). Find the section called Compiler Defines. Look for the define: nginx Copy Edit VISU_USEPROPERTYINFO Delete it from the list, or uncheck it if it’s a checkbox. Save your changes and try compiling the project again. → This is the right approach if you don’t need property handling for visualization elements.

Post by ganassa on Custom colors in Ladder diagrams? ^{CODESYS Forge talk (Post)}
How can I change the default color - blue - for active lanes, contacts and coils? I'd like a lighter color. After having failed in finding a related option in the IDE, I've looked at the "Default.editortheme" file in CODESYS' directory, but couldn't see any related option. Thank you

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.

Hi everybody, I want to execute more than once cam fb simultaneously so blending cam and thus blending velocity without stop motion. But as far I know codesys dont support directly cam blending. But I beleeive there is a some solving. I request your support. But there is important thing is I want to change cam table cam on the fly. For example FlyingSaw application change cutting lenght.

Hello everyone, does anyone know what this error means: Internal Error in code generation for http://opcfoundation.org/UA/DI/: Dimensions must be empty. I use the standard information models from Codesys and haven't even called the Information Model, but my program can't compile. the only thing I did was to insert the Communication Manage.

Post by ulvis on Where to find the OPC-UA Information Model Repository ^{CODESYS Forge talk (Post)}
Now, for CODESYS v3.5 SP21 I can no longer find the "OPC UA Information Model Repository" entry to add as a command. In the "Tools" menu it is listed but greyed out, reporting "Plug-in is not available". So how do I add the Plug-in?

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 eschwellinger on TargetVisu option missing in IDE ^{CODESYS Forge talk (Post)}
It is not needed to add Targetvisu connector - for using the TargetVisu for Linux. The reason is - TargetVisu for Linux is basically a remote TargetVisu which could connect to any CODESYS plc not only the loacal one - therefore only a Webvisu connector is needed to have it work. & it seems a bug with this anoying update proposal.

Post by wagokurt on CODESYS Visualization M License Fails to activate on Linux SL <sup>CODESYS Forge talk (Post)</sup>
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 antonz on CoDeSys v3.5: creating libraries for both 32-bit and 64-bit controllers <sup>CODESYS Forge talk (Post)</sup>
Thanks Tim. I would think it somehow is relevant when creating a compiled library, but that may very well not be the case. If I understand you correctly, then the same compiled library created from my source code would work for both 32 bit as well as 64 bit controllers.

For reference, it was just me being unfamiliar with EtherCAT in CoDeSys. Anyone with knowledge who would have opened the ScanResult screenshot would have identified that the preceding EK1100 was the device missing in the library. Bottom line - Do something else for a while and then get back at it with fresh eyes!

Hi ustad41, cams can be buffered using the BufferMode input of MC_CamIn. If the end- and start-velocity of two buffered cams are not zero, there will be no stop. Not sure this answers your question. Cams can be changes on the fly by aborting the active cam. Please see [0] for details on switching cams.

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.

Hi liai, is it possible, that SM3_Basic is missing in the library manager? (It should be inserted automatically when adding a Cam table, along with the other motion libs.) You can add it manually and see if that solves the compile errors. Best regards, Georg

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!
